Abstract
Varian’s earlier process analyzer, the PA-7, is now being replaced by a new solid state instrument, the PAT-20, with improved reliability and performance and simplified operation. The instrument measures the NMR signal of the protons in the sample, integrating the narrow line to give a quick and accurate quantitative analysis of water or oil in a previously weighed sample. The result can be displayed on a recorder or on a digital readout. It can also be fed directly into a computer for on line process regulation. A short description of the construction of the instrument is given and the principles of operation are explained.
