Mercury (Hg) vapor analyzer Tekran Instruments Corporation

The Tekran Model 2537 Mercury Vapour Analyzer provides continuous analysis of total gaseous mercury (TGM) in air at sub-ng/m3 (parts per trillion (ppt) and parts per quadrillion (ppq)) levels.

The instrument samples air and traps mercury vapour into a cartridge containing an ultra-pure gold adsorbent. The amalgamated mercury is thermally desorbed and detected using Cold Vapour Atomic Fluorescence Spectrometry (CVAFS). A dual cartridge design allows alternate sampling and desorption, resulting in continuous measurement of the air stream.

Key Features

- Patented dual cartridge design.
- Capable of unattended operation for extended periods.
- High precision mass flow meter provides accurate measure of total sample volume.
- Ultraviolet excitation source is temperature controlled and features closed loop optical intensity control for optimum stability.
- Simple menu based operation allows modifications of all operational parameters to suit any monitoring application.
