Infrared Analysis

SKU: LTINA00CENDuration: 60 Minutes

The purpose of this course is to present a fundamental treatment of how to perform infrared (IR) analysis. The course starts by describing the basic concepts underlying IR, and then describes several methods used to prepare samples for analysis. After the major components of a typical IR spectrometer are identified, a demonstration of how to perform IR analysis is presented. The course concludes by introducing the graph used to show the results of an analysis, describing the characteristics of a typical IR spectrum, and identifying different ways IR results can be used in chemical plants.
