Use of Infrared Spectroscopy in Permeation Tests

  title={Use of Infrared Spectroscopy in Permeation Tests},
  author={Jimmy L. Perkins and Michael C. Ridge},
The use of infrared (IR) analysis for permeation work has both advantages and disadvantages. Most advantageous is its ability to monitor a permeation test constantly without taking samples, as is necessary for most gas chromatography (GC) systems. Infrared detection also requires little attendance, and breakthrough time is very easy to discern. Disadvantages include a longer delay in detected breakthrough time (because of the volume of the system) than with GC systems. However, the relative… CONTINUE READING
