Application of a high-temperature tube furnace and liquid scintillation counter for radioactivity determination of 14C and 3H in solid waste samples

Assimilation and transport of organic bound tritium in an irrigated pine forest

“…For 14 C analysis, the Pyrolyser was used to liberate CO2 from the samples via decomposition (see Table S2 for details). 34,35 The liberated CO2 was then trapped in Carbo Sorb E (an organic alkali solution of 3-methoxypropylamine) trapping solvent (PerkinElmer Inc., Packard BioScience B.V., Groningen, The Netherlands) and 14 C was quantified by LSC using the Quantulus in the Carbo Sorb E cocktail after addition of Permafluor E. Estimated net activity rates have been reported in Bq g -1 (of fresh weight material) correcting for matrix effects. A series of blanks were run between sample sets to quantify any carryover, which was determined to be minimal from these studies.…”
