    Most organic and some inorganic compounds can be analyzed in the NIR region. For example, the 514 is used to analyze parts per million (PPM) or the percentage concentration of water in a variety of compounds (see Typical Applications).

  • Page 6: Modules (Condulets)

    1.0 Introduction The quantitative measurement of a compound using the 514 is based on Beer’s Law, which states that the intensity of a beam of monochromatic radiation transmitted through a sample decreases exponentially as the con- centration of the absorbing sample increases.
