Summary
Extraction of chlorophyll from leaf material with dimethyl sulphoxide allowed measurement of the attenuation of photon detection from a sealed miniature14C standard to be used for total chlorophyll quantification. Comparison between the use of a spectrophotometer and a liquid scintillation counter showed chlorophyll quantification to be accurate by this latter method over a wide range of concentrations. The method does not separate chlorophyllsa andb, but allows the rapid measurement of total chlorophyll concentration, and is suitable for automation.
