Field Analysis of Dissolved Gases in Lake Waters by Gas Chromatography

Source

Equipment for the analysis in the field of dissolved gases in lake waters by gas chromatography is described. It is portable and can be battery operated. Water from the required depth is pumped continuously through a small glass stripping device. It is equilibrated with flowing helium and the gases introduced into the gas chromatograph by a sample loop. Problems of oxygen and carbon dioxide invasion and degassing of supersaturated gases are avoided. The method will measure from 2 to 1000 micromoles/liter of carbon dioxide.
