Sample Oxidizerの使用経験

Abstract

The Sample Oxidizer automatically prepares samples for liquid scintillation counting containing singlelabel tritium (^3H), single-label carbon-14 (^<14>C) or both nuclides in double-label. Double-label samples of tritium and carbon-14 are chemically separated during preparation. Recovery of tritium was about 90% with 0.2 gram of most materials. Recovery of carbon-14 was about 85%. Memory effect for tritium and carbon-14 was less than 0.6% with most samples. But Sample Oxidizer was not suitable for fatty samples. We adopt the "Sample Oxidizer Method" as to tissues, the "Hyamine 10X Method" as to fatty samples and the "Direct Method" as to serum.
