摘要: A sample preparation method which permits liquid scintillation counting of aqueous suspensions or dry powders is described The addition 4% by weight Cab-O-Sil (finely divided silicon dioxide) to the gel produces a transparent and colorless stable for 1 2 weeks. Counting efficiency 65 14% reported C/sup 14/- H/sup 3/-labeled compounds, respectively, are soluble suspended in milk. (C.J.G.)
