Field or laboratory applications
FIELD or LABORATORY APPLICATIONS

MERCURY DETERMINATION

with RA-915+

  • mercury content in ambient air, detecting mercury spills

  • mercury determination in aqueous samples, EPA method 1631

  • direct (no digestion) analysis of soil,complex matrixes, EPA method 7473

  • mercury monitoring for indoor air (‘Instant’ NIOSH 6009 results)

  • mercury determination in natural gas or industrial emmisions monitoring

  • Air – 2 ng/m3 range -- 0.000005 - 0.1mg/m3liquids – 0.5 ng/lsolids – 0.5 µg/kg

  • background correctionZeeman effect with HF polarizationmodulation

  • size and weight460x210x110 mm; 7.5 kg

  • power supply220/110 Vac, 50/60 Hz;10/14 Vdc

with RA-915+

Multifunctional mercury spectrometer

Due to the low power consumption (15 W) and low weight (16 Lb. with built-in batteries) the spectrometer can be used for mercury determination in air and natural gas, samples of soils, rocks, water in laboratory as well as in field conditions.

ANALYTICAL INSTRUMENTATION


Ohiolumex co ra915 mercury 1276917

MERCURY DETERMINATION

with RA-915+

1. Real Time mercury Spectrometer with Zeeman correction for interferences.

2. Lowest Detection Limit, 2ng/M3

3. Real time measurements with MS Windows dataloging.

4. Wide measurement range, 0.000002 - 0.1mg/M3

5. Field performance verification cell

6. Simple to operate

7. Low maintenance with 48 hours repair/replacement policy

ANALYTICAL INSTRUMENTATION

MERCURY DETERMINATION

with RA-915+

No Effect of interfering gases

Gases in (high) concentration have no interfering effect

exceeding 100 ng/m3 or 0.0001mg/m3.

ANALYTICAL INSTRUMENTATION

C, ng/m3

Mercury distribution along the profile crossing the area of an unidentified ore mine and a smelter.

M –mineC – central part of mineS – smelterW – waste dump

Figure shows the results of mercury determination along the profile of a mine, smelter and a waste dump. The RA-915+ analyzer was placed in a car, and ambient air was continuously pumped through the instrument at a rate of 20 l/min. As can be seen, with the speed of the car at about 35mph, two high peaks were detected in the central part near the mine, smelter, and dumps.
