Direct thermal decomposition laboratory mercury analyzer RA-915 Lab

RA-915 Lab is the new direct fully automated laboratory mercury analyzer with 45 position autosampler. It provides accurate, reliable and cost-effective measurements in the broadest range of applications areas. The instrument analyzes solid, semisolid, and liquid samples with no pretreatment, reagents and almost no wastes. RA-915 Lab can be supplied without autosampler.

principle of operation

Atomic absorption spectrometry at 254 nm with Zeeman correction for background absorption makes interference-free measurements easy and quick and provides the most selective and sensitive analysis.

features and benefits

Direct analysis of solid, semisolid and liquid samples, any kind of sorbent traps
Unique analytical range extended up to 2 000 000 ppb
No sample pretreatment, no reagents, almost no wastes
No compressed gases (oxygen or argon), no pre-concentration on gold traps
Powerful and user-friendly RAPID software with flexible operation modes
No memory effect: a sample with low mercury concentration can be analyzed right after one having high mercury content
PC controlled programmable furnace temperature: optimal decomposition mode for any kind of samples
