Water Analysis at the highest level

Numerous gases are used worldwide, e.g. to keep food low in germs or to prevent insect infestation. Some of them are acutely toxic and their degradation product can be found as a residue in the product after use.

A worldwide problem in recent years has been the discovery of ethylene oxide (ETO) and its degradation product 2-chloroethanol.

You could call it a classic in pesticide analysis: the multimethod using QuEChERS.

QuEChERS stands for quick, effective, cheap, rugged and safe, which perfectly describes the characteristics of the method. It combines liquid chromatography with gas chromatography and thus enables several hundred residues of substances to be detected cost-effectively in one run and in a short time.

It is therefore an ideal basis for safeguarding a wide range of products and should not be missing from any monitoring programme.

The mold species was first described in 1901 in the “Annales de la Société Scientifique de Bruxelles” by Dierckx. To this day, and significantly in the period before the Internet, the species Penicillium citreonigrum has been described under four other species names.
As Penicillium citreonigrum is not described as having an increased water requirement, the species is not one of the recognized indoor humidity indicators.
