Performance Evaluation (PE) Samples for Phosphate

Performance Evaluation (PE) samples for phosphate are designed to be used as part of an ongoing quality assurance programme. These samples are supplied unknown to analysts who include them with their own samples in a normal analytical run. Phosphate standards are supplied in deionised water. Each sample carries a label quoting its unique sample reference number. After analysis the value obtained by the analyst for each PE sample is forwarded to OSIL where a certificate is issued showing the analyst value together with the true value and the error. OSIL is certified to ISO9000/2001 for the preparation and calibration of marine standards. Pack Size: Bottle of 50 ml

Prices include supply of PE samples and subsequent issue of certificate by OSIL.
