Remarks For analyses out of raw milk our MULTI-PT covers 19 different parameters and up to 10 different concentration levels for each parameter. For cream we offer 3 different concentration levels and 3 different parameters. Participation in all parameters is not obligatory; you have the possibility to sign up only for the parameter you are interested in. This allows you to optimise your participation costs. Depending on the parameter you are participating in, you will receive a sample set that consists of up to 26 different samples for raw milk analyses and of 3 samples for cream analyses. All methods will be considered, “reference” and “alternative” methods. Each analysis has to be performed under repeatability conditions. Participants will be informed on time how results have to be reported back to QSE (either online or by using a spreadsheet).
