METHOD AND APPARATUS FOR IN-SITU SPECTROSCOPIC ANALYSIS

摘要

A method and apparatus for in-situ spectroscopic analysis of a flowable material comprising a flow cell having a flow passage and means for introducing the flowable material into the flow passage, first probe means f or transmitting a given wavelength of light into the flow passage, second probe means for detecting the emission light from the flowable material, and contr ol means for providing the light to the first probe means and analyzing the emission light detected by the second probe means. The first and second prob e means include optic means that project into a region of reasonable flow in t he flow passage. The first and second probe means also have a path length in th e range of 1 .mu.m to 10 mm.
