Technology Description:

The Tekran(r) Model 2537A is a continuous Total Gaseous Mercury (TGM) ambient air monitor. It is unique in that it is the only continuous TGM ambient air monitor on the market. Its low detection limit (0.1 ng/m3 = 12 ppq v/v) allows measurement of background levels, emissions from landfills, incinerator plume tracking and industrial source localization.

          Mercury is absorbed onto pure gold absorbent traps and detected by thermal desorption and cold vapor atomic fluorescence spectro-photometry (CVAFS). Cartridge life is indefinite. An internal permeation source allows unattended operation and automatic recalibration. Dual cartridges provide continuous measurement of the air stream. Measurement time is 2.5 minutes.
Performance Status/
Limitations:

Atomic Fluorescence requires an inert gas carrier. A full size (T) cylinder of UHP argon will typically last or 2 to 3 months of continuous operation.

          A few other contaminants, sulfur the most common, can interfere with the analysis if present in sufficiently high concentrations.

          Note: Tests done show no interference from sulfur.
