Screening

At Normec, quality is paramount. Systematically screening samples for the presence of residues and pesticides affects the quality of your products. Residues and pesticides refer to the chemicals left on crops after the use of pesticides or other chemicals. Screening is an important part of quality control and food safety measures. It ensures that your products meet applicable standards and are safe for possible consumption.

Quality assurance

The quality of our results is continuously guaranteed by participation in various national and international ring tests in the field of pesticides (such as EURL, Fapas, QS, Bipea and LVU). These are independent controls that monitor the quality of analysis results from participating laboratories. Based on the results of these ring tests, the performance characteristics of the analytical methods are evaluated and adjusted. To date, we score very well within these ring tests.
