WebThis method covers the measurement of 231 Pa in water at activity concentrations between 0,1 Bq·l −1 and 100 Bq·l −1. Samples with higher concentrations than 100 Bq·l −1 can be measured if a dilution is performed. The method described in this document is applicable in the event of an emergency situation. Filtration of the test sample is necessary. WebThe method easily concentrated PFAS in 500 mL of water sample more than 40 times without any evaporation step. If needed, the samples can be concentrated more by evaporating the elution. Particular attention must be paid to verify that the laboratory environment does not contaminate samples and lead to false positives. Some simple …
