WASP Stock Samples

WASP stock samples are test samples sets surplus from completed WASP proficiency testing rounds and may be used as PT training samples to assess the performance of new analysts or as corrective action samples for analysts who have difficulties in obtaining good results in the WASP PT scheme.

Test samples are supplied with an assigned value for each analyte and a satisfactory range.The assigned values have been calculated as a trimmed mean from the participant data supplied for the particular PT round in question. The satisfactory range indicates the range between which results would have been awarded an satisfactory score in the WASP PT scheme has such a training sample set been analysed as an unknown WASP PT sample set.

Formal stability testing of these materials have not been carried out. However based upon expert opinion, supported by in-house data and published data on the stability of similar materials, the materials offered can be considered stable over the timescale suggested on the accompanying specification sheet.
