Measurement Procedure
Put the sample (from 20 to 300 mg) to the sample boat. Switch on integration of the analytical cell and insert the sample boat into PYRO-915+ attachment. Integration will be finished in 60-120 sec when the analytical signal goes back to the baseline.
Principle of Operation
Is based on the atomization of mercury contained in the sample in a thermal decomposition attachment PYRO-915+ and subsequent measuring the absorption of the 254-nm resonance radiation by mercury atoms using Zeeman correction for background absorption.
Areas of Application
RA-915M mercury analyzer with PYRO-915+ attachment can be used in food and oil-refining industries, medicine, for sanitary and environmental control.
Rapid-analysis of complex objects:
- soils, sediments
- rocks, ores, minerals
- crude oil, oil products, naphtha, petrochemicals
- coal, coke, fly ash, gypsum
- USEPA 30B, PS12B and CEN/TS 17286 sorbent traps
- passive air samplers
- waste waters, wastes, sludge
- food, nutritional additives, animal feedstuff
- biosamples: tissues, hair, urine, blood, etc.
- drugs and cosmetics, plastics, fertilizers, raw materials.
Demercurization monitoring:
- monitoring of a demercurization process involving any chemical reagents
- quality assurance of the demercurization.
