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 …

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 …

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 …

A fast, economical, and reproducible method for the preparation of green plant samples for
14 C quantitation by liquid scintillation spectrometry is presented. Uniform weights of green …

A nitric acid digestion method is presented for rapid and inexpensive preparation of 14 C-
labelled macrophyte tissue for liquid scintillation counting. No significant difference was …

A technique for routine liquid scintillation counting of 32P in dry ashed plant tissue by
utilizing Čerenkov radiation was shown to be effective when corrections for color quenching …

Extraction of chlorophyll from leaf material with dimethyl sulphoxide allowed measurement
of the attenuation of photon detection from a sealed miniature 14 C standard to be used for …

LIQUID scintillation counting of roots was investigated in connection with a study of the
uptake of choline sulfate-S35 by barley roots (l). Liquid scintillation counting of solid samples …
