One method suitable for detecting as many pesticide substances as possible is the multi-method DFG S 19, which is one of the methods we use at PhytoLab. This is published internationally under DIN EN 12393 (determination of pesticide residues in low-fat foods), and in Germany in the set of methods in accordance with Section 64 of the German Food and Feed Code (LFGB) L-00.00-34. Using this method, we can test around 250 pesticides at the same time, even in highly complex matrices, such as dried herbs. One important complementary technique to this method is the LC-MS/MS multi-method (with upgrade QUECHERS), with which polar compounds can be detected particularly effectively.
1. Pesticide tests in accordance with DFG S19 (in accordance with L00.00-34, DIN EN 12393):
2. Pesticide tests with LC-MS/MS (upgrade QUECHERS)
In addition, there are a number of mini-multi-methods or individual methods that we apply for certain groups of active ingredients or individual active ingredients:
