At-Line NIR Analyzer

At-line NIR analyzers perform at the process line with samples removed by hand and fed into the machine, allowing the analysis done on samples from many lots or stages of production. This technology is especially useful for at-line analysis because at-line NIR analyzers can use fairly large samples with no extra preparation needed. An at-line NIR analyzer uses near infrared radiation to cause vibrations in the molecules of the sample which create spectra that can be used to determine the chemical components of the sample. The at-line NIR analyzer works best when the machine has been calibrated to look for a specific substance. At-line NIR analyzers are used in medical labs, industry, pharmaceuticals, and food science to find moisture, carbon dioxide, oxygen, nicotine, and many other substances.

Considerations for purchasing an at-line NIR analyzer

There can be differences among at-line NIR analyzers, including how long analysis takes, can it analyze solid, liquids, powders, or some combination, how many samples can be analyzed at one time, and the source of the near infrared radiation.
