Abstract Ground, freeze-dried, 14 C-labelled rape (Brassica napus) leaf tissue was prepared
for liquid scintillation counting by the wet oxidation method of Mahin and Lofberg.(1) Heating …

Determination of 14C in solid residues and intact tissues has traditionally involved
combustion of samples to 14C02 (Fuchs and de Vries, 1972). However, recent meth allow …

Compared with sample preparation techniques which involve wet or dry combustion
(reviewed by Fuchs and de Vries, 1972), measurement of radioactivity in plant material by …

Four methods for the preparation of 14 C-labelled plant tissues for liquid scintillation
counting have been compared for accuracy and precision. The wet oxidation method of …

An apparatus for testing a plurality of liquid radio active samples contained in uniform
sample vials, where in the samples are advanced seriatim by a conveyor to a location where …

A persistent problem in preparing samples of radioactive plant tissue for scintillation
counting is that of reducing the colour quenching to acceptable levels. In a study involving …

This invention relates to liquid scintilation spectrome ters, and more particularly to a
scintillation spectrometer which is particularly adapted for the indentification and evaluation …

A method is described for the liquid scintillation counting of 14C in plant tissues. Samples
are fixed, in the scintillation vial, in a solution of ethanol and acetic acid (3: 1) and …
