Oxygen flask combustion analysis of 14C and 3H: Description of method and apparatus and summary of experience, with emphasis on analysis of low levels of activity

Abstract

Procedures and equipment used for oxygen flask combustion analysis of biological samples containing 14C and 3H are described. The method combines features of earlier, basic methods described by Kelly et al. (1) and by Kalberer and Rutschmann (2) and contains some of the more recent modifications of these basic methods. Emphasis is placed on features of the method which may be of particular interest in situations where capacity for efficient handling of large numbers of samples and reliability at low radioactivity levels are important factors.
