Revvity 3H Internal Standard

Revvity Determination of counting efficiency by internal standardization is the original analytical technique to which other efficiency determination methods are referred. Packards certified internal liquid scintillation counting (LSC) standards are calibrated in DPM per unit weight rather than DPM per unit volume. The advantage of calibrating in DPM per gram is that the calibration remains constant with changes in temperature. - REVPFZ (Additional S&H Or Hazmat Fees May Apply)
