Full Description
Tetrahydrofuran (THF) is used as a solvent for a variety of resins, plastics and elastomers. Biological monitoring is based on the analysis of THF in urine samples collected at the end of exposure or end of shift.
There are US and German guidance values to aid interpretation.
As THF is a volatile solvent, please ensure that the sample bottle is filled to the shoulder (but not more) to ensure no losses during transport and storage. As THF itself is measured, please ensure that contamination of the sample is avoided (ask workers to remove overalls, wash hands before providing a sample).
