Quantification of Ethyl Glucuronide in Hair: Effect of Milling on Extraction Efficiency

The objective of the study was to provide conclusive evidence for the effect of particle size reduction as by milling on the extractable content of ethyl glucuronide (EtG) of hair samples.

A number of real case hair samples and two pooled hair materials with EtG contents in the range of 10–30 pg/mg were systematically compared with regard to the
