Application Data Sheet

A guide to filling out the application data sheet with your customer

application data sheet ads
Application Data Sheet (ADS)
  • For all non-Standard Application Gas Chromatographs, the Application Data Sheet (ADS) is required before the GC Division can quote the GC
  • The ADS is also an excellent tool during the sales process to help prompt the customers for information and an aide to up-sell the GC, and even eliminate the competition
  • You should keep a blank application data sheet at-the-ready to fill out with the customer

Customer Information: this is contact details, and how you want the quote to be delivered.

Option Information

This section is ideal to be used with the customer to discuss the options for the controller, and the Analyzer.

model preference
Model Preference
  • Model Preference:
  • If the customer has a preference (e.g. They have an installed base of a particular model) for a style of GC, this should be entered here. Note that if the application is not suitable for the selected application, we will contact them to confirm the style of GC can be changed.
  • If the customer has no preference, then leave this blank.
  • Some reasons for a particular GC are as follows:
  • 700XA: DC power required. Small footprint. Do not want separate controller. C9+ or Dual Detector application. FID application.
  • Model 500: Installed Base of 500’s. Remote controller required.
  • 1500XA: Difficult application. Instrument air is available. The 1500XA will usually be selected by the application engineering department of the GC group when the application is more advanced.

Model 500



area classification
Area Classification

Area classification:

Area classification refers to the hazardous area rating required. For most applications it will be Class 1-Div 2, or Class 1-Div 1.

Agency Certifications refer to the third party hazardous area certifications required. CSA is the Canadian Standards Association (accepted in the US when certification is required) and ATEX is the European certification. If the end destination is in Europe, Asia or the Middle East, ATEX certification is usually required.

IEC-Ex is also available for the 700XA only.

available utilities
Available Utilities

Available Utilities:

For more complex applications, some external utilities may be required.

Instrument Air:When external “Block and Bleed” solenoids are required, or the 1500XA is being offered, clean dry instrument air with at least 110 PSIG is required.

Steam, Water or Nitrogen:For very specialized applications only.

gc mounting
GC Mounting

Pole Mount

GC Mounting:

The model 500 can be only mounted with a floor mount. The 700XA can also be supplied with a wall mount and a pipe mount.

The pipe mount is for a 3 or 4 inch pipe mount.

Wall Mount

Floor Mount

controller option
Controller Option

2350A Rack-mount with keypad and display

2350A Expl. Proof Integral mount with keypad and display


Integral – The 700XA and 1500XA use an integral controller. The model 500 has an optional “explosion proof housing” for the 2350A controller.

19” Rack-Mount – The standard offering for the Model 500 GC is a remote mounted “safe area” 2350A controller. This requires a 13 core (C6+) or 18 core (C9+) cable between the controller and the Analyzer Oven.

Keypad/Display – The 2350A controllers (remote or integral) has the option of a large keypad and 8 line/41 character display. The 700XA have the option of the full color LCD display with touch sensitive operation. The 1500XA always has the LCD Display.

power options
Power Options


The model 500 and 1500XA are available for 120 VAC or 240 VAC power supplies only.

The 700XA can use 120 VAC, 240 VAC or 24 VDC.

For destinations outside of the US, the power supply voltage needs to be confirmed as often 220/240 VAC is required.

of serial ports and config
# of Serial Ports and Config

This is a critical question which can help eliminate the competition!

Increasing the required serial ports to 3 or more can remove the opposition GC’s from consideration. An example application is communication to a flow computer, local operator access, and third-party access.

# of Serial Ports and Config:

We have up to 8 serial ports available on the Model 500, and 5 serial ports for the 700XA and 1500XA (with expansion cards).

Standard option is 4 for the 500, and three for the 700XA/1500XA.

RS 232 is a 3 wire used for short distance point to point communication for local access and locally mounted flow computers and RTU’s and control systems.

RS 422 is a 4-wire long distance point to point communication which can be multi-dropped.

RS 485 is a 2-wire long distance multi-point communication which is commonly used to RTU’s and flow computers and DCS systems.

data communication
Data Communication

Communication to the SCADA system, RTU or Flow Computer.

Analog. 4-20mA outputs. Rarely used today, but could be used for BTU output, Density or any component or calculated value.

Modbus. The most common serial communication method.

Foundation Fieldbus. The 700XA and 1500XA are the only FF certified GC’s on the market!

Ethernet. Modbus TCP/IP communication over a Ethernet connection. Ethernet allows for Modbus communications and diagnostic access over the same link at the same time.

Ethernet is not an option – it is STANDARD!All of the Emerson Gas Chromatographs now have Ethernet as standard. Even better, the 700XA and 1500XA have TWO Ethernet ports, one with a DHCP server and RJ45 connector for direct access with a laptop computer.

serial protocol
Serial Protocol

MODBUS MapsThe Model 500 uses a fixed SIM_2251 Modbus map but can use a fully configurable map using the Gould Modbus.

The 700XA and 1500XA can use fully configurable Modbus maps for all protocols.

Serial Protocol:

-SIM2251. This is the standard “Daniel” Modbus protocol which simulates the Modbus interface of the old 2251 controller. Sometimes also called ENRON Modbus. Most flow computers or RTU’s use this protocol and require little configuration.

-Gould Modbus. This is the Modbus protocol commonly used by PLC’s and DCS systems.

i o options
I/O Options

Analog Inputs – Available on the single detector model 500 and the all 700XA/1500XA’s. (not available on the C9+ or dual detector model 500). Can be used for other analyzers (e.g. Moisture or H2S) or for pressure transmitters on the Carrier gas and Calibration gas.

Digital Inputs– Can be used for pressure switches, or for switching to “alternative stream sequences” mode. The alternative stream sequence mode is a useful tool which allows for a GC to have two stream sequences. For example, the normal mode could be just analyzing stream 1, and the alternative stream sequence can be stream 1, stream 2, stream 1 etc.

Very useful for redundant systems and for measuring two streams where only one is active at a time.

This is a critical question which can help eliminate the competition!

The I/O capabilities of the Emerson GC’s are a major advantage over opposition GC’s. The 700XA/1500XA can use the ROC expansion cards to provide a large range of additional I/O


Digital Outputs: Can be connected (via a relay) to solenoids, valves or alarm contacts on supervisor systems for alarm activation. One user used the mA input for a H2S signal, and connected the digital out to the slam-shut valve to provide a high H2S shutdown on the pipeline inlet.

Analog Outputs:Std is 4 non-isolated outputs, options are 4 non-isolated/4 isolated outputs (8 total) or 12 non-isolated outputs. Often used for calculation outputs (such as BTU or specific gravity) or component composition values to non-serial communicating devices.

This is a critical question which can help eliminate the competition!

The I/O capabilities of the Emerson GC’s are a major advantage over opposition GC’s. The 700XA/1500XA can use the ROC expansion cards to provide a large range of additional I/O

auto calibration

Auto-calibration Preference:

For gas applications, the GC can be set to auto-calibrate. This is standard for custody transfer applications.

For liquid applications, auto-calibration is typically not used as setting the liquid calibration standard for analysis is a manual procedure.

sample system
Sample System

Sample System Required:

Generally the GC will be supplied with a sample conditioning system (SCS) mounted under the Analyzer Oven.

-None. The customer will supply the sample handling system and will ensure a dry-gas sample will be supplied to the GC.

-Attached. The standard offering with the SHS mounted below or beside the GC.

-Remote. The sample system is built separately to the GC and is mounted remotely from the GC. Typically when the GC is installed in a building the SCS mounted on the outside wall.

auxiliary options
Auxiliary Options

Auxiliary Options:

-Carrier Gas. Includes Carrier gas bottles, pressure regulators and manual switchover manifold.

-Cal. Gas. Includes appropriate calibration gas(es), and pressure regulators.

-Probes. Sample probe(s). Probes will be selected to be appropriate for the application as described on the Stream Composition Sheet (sheet 2).

-Tropicalization. For salt laden or very corrosive environments the GC and Electronics boards can be coated with a clear coat paint.

factory field support
Factory/Field Support

Sell the FAT!

The Factory Acceptance Test allows the end-user to become familiar with the GC before it is shipped. The technician who configured and tested the unit will be able to give unit specific training that will make start-up and operation significantly easier. This training is conducted in the Houston factory.

FAT– Factory Acceptance Test. A representative of the end-user comes to the factory (in Houston) and carries out a checkout test with the lab technicians.

Start-up – A factory trained technician will come to site to start the unit up for the first time.

Training – Training can be provided in Houston (regularly scheduled throughout the year) or onsite as a part of the start-up visit.

special instructions or notes
Special Instructions or Notes

Special Instructions can save time and confusion

If the customer has any standards or referenced documents, include the details here!

Any special instructions such as shelter requirements, analysis time limits or any other information that will be important to obtaining an accurate quote.

If there is customer specification documents to refer to, they should be listed here.

stream data
Stream Data

Stream Data Sheet

This page is where the individual stream data should be entered. Calibration Gas Stream information does not need to be entered here, as this will be considered automatically by the application engineering team. Note that there are 4 streams available. If more streams are required, just copy this page and include it in the submission.

The Model 500 can have up to 12 streams (including calibration gas) and the 700XA can have up to 8 streams (7 samples and one cal). More streams can be accommodated with discussion with the factory.

Gas and liquid applications can be done on the same GC, however, application engineering will decide if it is appropriate to mix two applications on the one GC.

ads stream data sheet
ADS – Stream Data Sheet

Customer information:

This should be the same as the first page.

ads stream data sheet1
ADS – Stream Data Sheet

Stream Parameters:

Stream Tag #

Stream name – for example “De-Butanizer Bottoms”

Process Control or Monitor – Will the stream composition be used as a part of the process control scheme, or is it for monitoring only. This is used for process applications to decide the tradeoff between component separation and analysis time.

Pressure at Sample Point – Required information to ensure that the sample will be taken in a single phase (gas/liquid).

Temperature at Sample Point – Required information if a sample probe is being offered. This is used in conjunction with the pressure and nominal composition to determine that the sample is single phase (gas or liquid) and therefore can be sampled accurately.

ads stream data sheet2
ADS – Stream Data Sheet

This is important!

The sample must be single phase (gas or liquid only, not both) to get a representative sample. The pressure and temperature is important to determine the phase state of the sample which is used in the design of the sample system.

Phase at Sample Point – used in the determination of the sample probe to be used, and the sample handling system to design.

Tap Distance to Analyzer – Used to determine the location of the Sample Handling System and to size the sample lines.

Return Sample to Process? – Generally the vents from the GC will go to atmosphere. The system can be designed (if required) to return the unused sample back into the process, usually for environmental reasons.

Return Pressure – If the sample is to be returned to the process, the return point pressure is required to calculate the flow rates through the system, or to determine if a sample pump is required.

Contaminants – Any hazardous (to components or humans) or significant contaminants need to be identified.

ads stream data sheet3
ADS – Stream Data Sheet

Stream Components:

The name of the stream components and the units should be entered into these columns.

Note that allthe components of the stream should be entered, not only the components to be measured. If there is a significant component that is not to be measured, it is important to list it so that the application engineers can ensure that it will not affect the measured components. For example, if there issignificant levels of H2S (>10ppm), but only the hydrocarbons are to be reported (they may have a separate H2S analyzer), the H2S value must be included in the component list.

ads stream data sheet4
ADS – Stream Data Sheet


The concentrations of each component normally expected to be seen in the stream should be entered in this column. Note that this does include the components not to be measured, but are to be found in significant quantities in the sample stream.

ads stream data sheet5
ADS – Stream Data Sheet

Choose wisely!

Often all of the components will be listed to be measured, when only two or three components are important. The fewer the components to be measured, the quicker the analysis time. The more components, the longer the analysis time. Discuss this with your customer to determine what they really need: Measure everything ormeasure fast?

Measured Range:

The minimum and maximum measured concentrations should be entered in these columns. Note that this is only for the components to be measured and reported, not the components which are in the stream, but are not to be measured.

ads stream data sheet6
ADS – Stream Data Sheet

Choose wisely!

More streams mean longer update times. Also, a GC will need maintenance as some stage, so if all the streams are in a single GC, all measurements will be lost during this maintenance time. Often it is better to spit multiple measurements across two or more GC’s to speed up update times and provide process measurements when one analyzer is down for maintenance.

Stream 2, 3 and 4:

For multiple stream applications, the information for the other streams are entered here. If more than 4 sample streams are required then a second stream data sheet should be completed

sample probe configuration
Sample Probe Configuration

The sample probe configuration sheet is to be completed if the customer wishes to purchase the probe as a part of the package.
