You may use any method of analysis you wish.

FAPAS® quality control test materials are real food matrices with one or more properties that have been sufficiently well established from the results of laboratories participating in a proficiency test to be used by laboratories as quality control materials.

The assigned value has been derived as a consensus of a number of laboratories using a variety of methods. The satisfactory range indicates the range between which results would have been awarded a satisfactory z-score in the proficiency test. The satisfactory range is set as a range that is considered fit for purpose and reflects the expected interlaboratory reproducibility.

Full details of the statistical methods used by FAPAS® are given in our protocol (downloadable from our website).
You should fully homogenise the material before taking a representative sample.

† Formal stability testing of this material has not been carried out beyond the scope of the proficiency test. However based on expert advice, published literature and previous experience, FAPAS have established a date until which it is considered that the material will remain stable. This includes a short period after the available until date for testing.
