advice and assessment in quality management
In the field of environmental chemistry we run PT-Schemes since 1999.
We conducted more than 160 PT-Schemes in this period of time
for a wide range of analytical methods
in environmental and industrial chemistry.
So far, more than 600 laboratories from
Austria, Belorussia, Belgium, Chile, France, Finland, Germany, Greece,
Italy, Liechtenstein, Luxembourg, Netherlands, Spain, Sweden, and Switzerland
participated in our schemes on a voluntary basis.
