Product Overview

HM-CGQ is a benchtop cold vapor atomic absorption mercury analyzer for gaseous mercury samples. Mercury vapor is carried into an absorption cell and quantified from its absorption of 253.7 nm ultraviolet light against a calibration curve.

For gas measurement, a gold-film trap collects mercury as an amalgam. Thermal desorption at 800 °C releases mercury vapor into the absorption cell.

Key Features

Android 10 operating system with a 7-inch color touchscreen.
Automatic zeroing, one-key measurement, live curves and instrument status prompts.
Shielded low-pressure mercury lamp optical system and a corrosion-resistant enclosed gas path with drying.
30-minute warm-up and an integrated thermal printer for measurement reports.
Wi-Fi software updates, wireless data upload and client-side data management.
Gold-film trap capacity greater than 1000 ng of mercury.

Applications

Gaseous mercury analysis for ambient air, workplace air, industrial emissions and atmospheric mercury research.

Operation and Support

Complete warm-up and calibration before measurement. Collect mercury on the gold-film trap, then insert it into the thermal-desorption port for measurement. Review the live curve and result, then save or print the report.
