Long Title: IUPAC Gold Book - quenching correction
DOI: 10.1351/goldbook.Q05009
Status: current

Definition
Correction for errors due to different quenching for standards and test portions. When using liquid scintillation detectors these corrections can be based e.g. on the standard addition or sample channels ratio method or the use of automated external standardization.
