Ultratrace Portable Total Gaseous Mercury Vapor Analyzer Gardis-7

Mercury Vapor Dosing Device GA-7300

Model GA-7300 Mercury Vapor Dosing Device is used as the calibration source to perform adequate mercury analyzer QA/QC procedures. It is a handy, small and lightweight device which can be operated under wide temperature changes. The calibration device is designed to inject precisely known mercury vapor doses down to as low as a few picograms Hg, which is particularly useful for the mercury analyzer performance checking in the Hg environmental measurements range.

The Model Ga-7300 Dosing Device can be coupled to the Mercury Analyzer Model Gardis-7 as an accessory device and does not require any separate communication channel or feeding source. The dosing device is operated as an integral part of the analyzer and is controlled from the PC together with the Gardis-7 Mercury analyzer. Calibration against zero-air, as well as by the standard addition method is enabled.
