The Tekran Mercury Analyser utilises gold cartridge capture combined with atomic fluorescence. Hgo is collected onto a pure gold collection cartridge, (no memory effect).
Mercury is then thermally desorbed (with zero air as a carrier gas, eliminating any interference) and the sample is passed into the reaction chamber where Hgo levels are detected using atomic fluorescence. An optical feedback loop for constant lamp intensity and optical path Argon purge provide a stable and reliable detector
The Model 2537B is the world standard for low level ambient air mercury monitoring.
