Determinands

WEPAL/QUASIMEME offers different proficiency tests in which various determinands can be determined in different matrices. If your laboratory is looking for a proficiency test of a particular determinand or determinand group, you can choose from the alphabetical list below. It shows per determinand group the range of the different available matrices. By clicking on the programme, you will be forwarded to the detailed information of that specific proficiency test.
