Mercury analyzer RA-915M

monitoringprocesslaboratory

RA-915M with PYRO-915+ attachment is a versatile tool for fast direct analysis of all kinds of solid, liquid, and biological samples from ppb level. Even the complex-matrix samples are analyzed ‘as is’ without pre-treatment. No reagents or compressed gases are required. The routine analysis takes 1–2 min. Programmable PYRO-915+ furnace enables optimal samples decomposition and study of the mercury thermospecies having various binding energy with a sample matrix. Direct thermal decomposition technique meets national and globally accepted standards such as ASTM D6722, D7622, EN/TS 17286, US EPA 7473, 30B, PS12B, SN/T 4429.2-2016, HJ 923-2017, and others. RA-915M analyzer can be used separately for real-time mercury measurement in ambient and indoor air. Other Lumex Instruments attachments are available to extend RA-915M functionality (RP-92 for Cold Vapor technique, RP-91NG for direct analysis of gases). PRINCIPLE OF OPERATION Direct thermal decomposition followed by atomic absorption spectrometry at 254 nm wavelength with Zeeman correction for background absorption makes interference-free measurements easy and quick. The technique ensures the most selective and sensitive analysis without matrix effects. FEATURES AND BENEFITS Direct and fast analysis of solids, liquids, and biosamples Broad measurement range: more than 5 orders of magnitude Low limit of detection and highest selectivity due to Zeeman background correction No need for sample pretreatment and reagents reduces analysis cost Safe and simple operation: no compressed gases (oxygen or argon), air is used as a carrier gas
