Ultra trace Portable Gaseous Mercury Analyzer Gardis-7

Ultra Trace Portable Gaseous Mercury Analyzer Gardis-7 is an instrument featuring excellent detection limit of 0.5 pg Hg (mass), or <0.1 ng/m3 Hg (concentration) and not requiring any carrier gas.

With its small dimensions and weight, it is the handiest product in the ultra-trace sensitivity class on the market.

Complies to the standard EN 15852:2010.     

Calibration device model GA-7300

Calibration device model GA-7300 is a miniature instrument intneded for the automated and precision calibration of mercury analyzer. Basic version reproduces doses from a couple picograms to hundreds of picograms Hg, which is ideal for the indoor/outdoor background monitoring. Calibration can be performed against zero-air or with a standard- addition method.

All equipment can be fed from 12 VDC (directly) or from 110 / 220 VAC via a power adapter (included)


  • Indoor / outdoor pollution source tracking by bringing the analyzer by hand or by placing the equipment in a car, in a boat, or any other convenient mobile platform, to screen ambient mercury on your way.
  • Atmospheric air quality studies at EPA stations or using weather-proof enclosures.
  • Detecting traces of mercury with different experimental setups: flux chambers, field traps. Probing interstitial air in the snow, in the soil, etc.
  • Analyzing liquid samples for mercury (oxidized water samples, digested biota and other). Accessories for semi- automated analysis of liquids are available.
