Analysis of mercaptans (DMS, DMDS) in air or water - « Purge & Trap » (Range 0.02 to 10 ppb)
Chromatotec analyzes sulphur compounds in gaseous form in the sea water or the air with a device which has a sulfur specific detector.
It allows in particular the measurement of dimethyl sulphide (DMS), volatile sulphur compound of biogenic origin, produced in 90 % in the oceans and which would be involved in the regulation of the greenhouse effect (concentration around 50 ppt).
The analysis of DMS requires a sensitive method. First, the sulphur compound must be concentrated before being analysed by Gas Chromatography. This step of pre-concentration is realised on a cooled trap (sampled volume ≈ 200 ml) after the purge of DMS.
The DMS is then thermo-desorbed, injected into the column and analysed by the specific detector.
