These standards are recommended to establish quench correlation curves for more heavily quenched samples. The improved efficiency correlation contributes to higher accuracy in the measurements of samples which may be difficult to count correctly. This series only differs in composition from the standards above by the concentration of the quenching agent used.
PerkinElmer provides 3H and 14C standard sets for testing PerkinElmer’s scintillation counter performance, as well as internal standard capsules for preparing your own 3H and 14C standard solutions. The unquenched and quenched standard sets are manufactured at PerkinElmer in controlled environments. They are prepared gravimetrically from NIST traceable solutions. After preparation, all standards are QC tested with calibrated counting systems at PerkinElmer.
