The result of spring proficiency test 2019 was published recently. We are glad to announce that we passed again with excellence!


65 laboratories were participating in the 26th analytical competence test for QS-approved laboratories. The labs were challenged to  determine eight active substances added to an onion test matrix, of which 2 actives could  be determined only by application of single methods. Eight labs failed in this respect.


Analytically onions belong to the most demanding matrices in residue analysis, as they contains high amounts of natural sulphur compounds which can lead to disturbing matrix effects.

Out of the 57 successful labs 31 achieved the maximum score – among them AGROLAB LUFA !


Congratulation to the colleagues in Kiel!
