1. Gloveboxes with analytical equipment including densitometer and analytical balances.

2. The error is less than 4%, and the apparatus used is far more simple than the alternative scanning densitometer.

3. ‘The chromatogram produced can then be used to give an Autoradiograph so the compounds that the radioactive material has been incorporated into can be readily identified.’ ‘The Autoradiographs were scanned with a densitometer, and the signals were quantified.’ ‘We assessed band sharing on polyacrylamide gel Autoradiographs.’
