Improved double-vial radiorespirometric technique for mineralization of C-labeled substrates.

M F Coveney1, R G Wetzel.   

Abstract

New procedures which simplify sample preparation and improve counting efficiency were developed for double-vial radiorespirometry. Under certain conditions, efficiency of fluor-NaOH-impregnated wicks was not stable, but was adversely affected by water vapor, NaOH concentration, and CO(2) loading. Glass fiber wick material treated with a methanolic fluor-NaOH solution showed improved C counting efficiency (58%) compared with previous methods.
