In response to customer requests for an expanded selection of certified environmental reference materials (ERMs), Wellington conducted an interlaboratory study in 2018 and was able to characterize three separate fish materials for select persistent organic pollutants .

Certified analyte concentrations were derived using data received from at least 10 analytical laboratories accredited to ISO/IEC 17025 and data were statistically analyzed using the Q-method/Hampel estimator ( robust method, ISO 13528:2015).

As a result, Wellington Laboratories are pleased to add WMF-02, WMF-03 and WMF-EX to their product line of Environmental Reference Materials
