Revvity Internal Standard Kit, 14c-O For Organic Samples

Internal liquid scintillation counting (LSC) standards enable determination of counting efficiency. Determination of counting efficiency by internal standardization is the original analytical technique to which other efficiency determination methods are referred. Certified internal LSC standards are calibrated in DPM per unit weight. The advantage of calibrating in DPM per weight is that the calibration remains constant with changes in temperature.
