THE DEVELOPMENT OF MEASURING SYSTEMS FOR PRIMARY CALIBRATION OF ORDNANCE CORPS TEST EQUIPMENT

摘要

One of the most important methods available for the estimation of moisture in non-aqueous systems is the Karl Fischer method developed in 1935, although newer methods such as continuous electrolysis of water 2 absorbed by phosphorus pent oxide, infra-red absorbance by water in the sample, infra-red absorbance by acetylene produced by treatment of the 4 sample with calcium carbide and gas chromatographic measurement of acetylene produced similarly have been introduced, the Karl Fischer method continues to be widely-applied. It is clear from a reading of the literature
