Quartz – Gold – Hyperbolic and Beautiful!

Why quartz?

  • Low coefficient of linear expansion (expansivity; α)
    • dL = α L0dt [t = ºC; dL = change in length (m); L0 = length at 0 ºC]

Why gold?

  • Inert material with excellent electrical properties for high voltage

Why hyperbolic?

  • Ideal electrical field is generated by hyperbolic surfaces (NOT ROUND)

Much more than just a beautiful piece of glass

key features of direct communication between 7890b and 5977a
Key features of “Direct Communication” between 7890B and 5977A

Safety Control

If 5977A MSD pump fail, 7890B will shut off the gas supply

Helium carrier gas : gas waste is eliminated

Hydrogen carrier gas: risk of explosion is reduced

Cool Down MSD Faster (FastVent)

When MSD Vent Cycle started, GC will cool down MSD analyzer at the optimum gas flow to MSD.

 40% faster when cooling down from 280C to 100C (< 25 min)

5977a gc msd idl specification
5977A GC/MSD IDL Specification

These are installation specification, performed on customer site, immediately after installation and carry a lot more value than a reference specs.

*Systems without an Autosampler will have only S/N specification.

IDL is a statistically derived value from the precision (%RSD) of 8 consecutive, splitless injections of 100fg OFN at 99 % confidence level. The more precise instruments (lower %RSD) will generate lower IDLs.

The Agilent 7890B/5977A with an ALS or CTC autosampler has the following specifications:

why idl specification is useful for the 5977 in sim
Why IDL specification is useful for the 5977 in SIM?
  • Influence of Noise in S/N specs
  • In SIM (or MS/MS) when the Noise is too low, such as during acquisition of an OFN standard, S/N results may not give the best characterization
  • If the noise level is insignificant - varies a lot and too low- the derived value from it (S/N) also becomes insignificant
  • Value of IDL
  • IDL is derived from reproducibility/precision results, the same metrics most users utilize every day in their work. The IDL statistical process is the same used for Method Detection Limit calculations, and the %RSD values are tools to monitor analytical performance
  • IDL characterizes the whole system – AS, GC, MS- giving confidence in overall reliability. It is the results of 8 consecutive injections, unlike S/N in a single shut, which can be influenced by many parameters/conditions
the influence of the low noise on s n values same data file rms 5 second noise region
The Influence of the low Noise on S/N valuesSame Data File, RMS, 5 Second Noise Region

A 0.01 min. shift in the noise regionresulted a 6000 higher S/N value.

When the noise is insignificant (low), the derived S/N value is also insignificant!

Noise region: 5.65min - 5.73 min

S/N: 10785

Noise region: 5.66min - 5.74 min

S/N: 3335
