A New Sensitive and Portable Mercury Vapor Analyzer Gardis-1A

  • Chapter
Mercury as a Global Pollutant

Abstract

A possibility to build a mercury (Hg) analyzer based on the cold vapor atomic absorption spectrometry (CVAAS) with a sub-picogram detection limit was investigated. Construction of the gold traps and the optical cell, carrier gas flow rate and gold traps heating power were chosen in order to effectively concentrate sampled Hg vapor and to obtain highest possible response in the optical and electronic system. The newly created analyzer is able to detect 0.5 pg of elemental Hg vapor. Optimization of construction resulted in stable performance and good selectivity for gaseous Hg of the analyzer. The instrument is commercially available.
