Definitions

  • the technical field generally relates to spectrometer analyzers, and more particularly to portable spectrometer analyzers and related methods for analyzing liquid samples.
  • Conducting water analysis often includes colorimetric and spectrometric analyses using detailed procedures and chemical reagents to determine the desired information. Most often these analyses are done in a laboratory setting for high accuracy and repeatability. Although it can be desirable to have water analyses done in the laboratory, it is often not convenient and can lead to significant delays between sample taking and obtaining the results. To manage this delay, a field test kit can be used from which the basic colorimetric and spectrometric analyses are performed. These field test kits inevitably need to be small, light and portable so that they can be brought to the sample location where the analysis is done.
