→ control of the global adjustment of the instrument (slope and mean deviation) and internal settings (linearity and intercorrections for MLRs only),
→ "simple" precalibration of the instrument: adjustment of the final equation (y = b.X+a).
→ "complete" precalibration of the instrument: adjustment of the crossed correction factors from the raw signal and the final equation (y = b.X+a) for the MLR prediction models.
Note: An adjustment of the bias of the instrument using milks representative of the milks analysed is absolutely necessary after an adjustment using the precalibration samples
any analyser based on the principles described in ISO 9622|IDF 141
1 inseparable group of 13 raw milk samples with amounts varying from:
- fat: 1.9 to 5.4 %
- protein: 2.1 to 4.1 %
- lactose: 4.5 to 5.8 %
- dry matter: 9.7 to 14.6 %
addition of Bronopol to the samples (final concentration: 0.02 %)
60 ml polyethylene screw-capped vials with airtight seals
monthly and on request (subject to availability), in insulated box with ice packs by express carrier (see regulation for shipping times)
For an order without annual subscription, send your order form before 3 p.m., otherwise packages can be sent the following day (valid from Monday to Wednesday) (except for countries outside UE - Outside EU, time before dispatch may take up 7 days, the time necessary to obtain customs documents)
determined by the results of an expert laboratory and checked by a FTIR analyser, using the following methods:
