摘要:

An improved method is described for the extraction of14C from biological samples, based on the wet oxidation techniques of Snyder and Trofymow6. Evolved14CO2is trapped in a 2M NaOH solution, and subsequently mixed in a scintillation cocktail for ß counting. Recovery of14C is consistent between batches, with an average recovery of 97.2% over fifteen standards. The technique described does not involve large capital expenditure and is relatively rapid.
