5371464 Apparatus for in-line analysis of flowing liquid and solid materials by nuclear magnetic resonance

Abstract

A flow through in-line NMR testing apparatus. Incoming fluid (70) is diverted into a sampling conduit (74) and thence into a rotatable test tube (80). An NMR device (108) is coupled on line (110) to coil (92) in cavity (93), to pulse the coil and to detect NMR signals generated by the material under test. With valves (76) and (106) open and valve (73) closed, continual flow of fluid through test tube (80) can occur. NMR testing can then occur while the material under test flows.
