Trace gas analytics

Besides specifications like moisture- or oil vapor content, clear identification and the level of purity of gas are being defined. The Ph.Eur. especially defines pharmaceutical nitrogen with a purity of at least 99,5 % whereas remaining trace gases have maximum residue limits as well. Among these are carbon monoxide, carbon dioxide Zu diesen gehören Kohlenstoffmonoxid, Kohlenstoffdioxid, argon und oxygen.

Using a mobile gas chromatograph, DPhE can identify nitrogen and determine CO, CO2 and Ar content exactly and according to the requirements of the Ph. Eur. Oxygen content is determined precisely in ppmV (part per million by volume) with an electrochemical measuring cell.
