Tekran 2537A Mercury Vapor Analyzer

Tekran 2537A is a fully automated analyzer designed for continuous monitoring of total gaseous mercury (TGM) in ambient air with ultra-trace sensitivity. It operates based on cold vapor atomic fluorescence spectrometry (CVAFS), using dual gold cartridge traps for alternate sampling and desorption, enabling uninterrupted measurements. With a detection limit of <0.10 ng/m³ and a linear range extending up to 10,000 ng/m³, it offers high precision and flexibility for both short- and long-term atmospheric mercury studies. The system minimizes contamination through sealed sample pathways and automatic cartridge cleaning to eliminate memory effects. A built-in microprocessor allows full programmability of the sampling cycle, desorption steps, and flow rates. Calibration can be performed manually or automatically using an integrated mercury vapor permeation source. Analog, digital, and RS-232 outputs facilitate integration with data acquisition systems, and the instrument is compatible with most data processing software. The Tekran 2537A is widely used in global mercury monitoring networks and is ideal for high-resolution temporal studies of mercury in the atmosphere.
