Monte Curcio instruments. Tekran 2537 - Total Gaseous Mercury Analyser

Monte Curcio (MCU) instruments: Tekran 2537 Total Gaseous Mercury (TGM) analyser. The Model 2537A 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.

Statement
A precision mass flow meter (MFM) is used to measure sample flow rate through the cartridge. The microcomputer integrates flow rates over time to provide the total volume of air measured for each sample. The instrument is supplied with volumes referenced to Normal temperature and Pressure (NTP). A programmable mass flow controller (MFC) allows the flow of carrier gas to be altered for optimum performance during the various steps of the desorption cycle. The instrument has provision for two methods of calibration: manual injection and, for analysers so equipped, a mercury vapour permeation source. Permeation source calibrations may be initiated automatically at regular intervals, allowing long term unattended operation. It is also possible, at any time, to manually initiate a recalibration using the source.//Ref. Operation manual Model 2537 (http://www.tekran.com) and GMOS SOPs (http://www.gmos.eu)
