Using light to reveal facts

Spectrometry is a technique used to assess the concentration or amount of a given chemical (atomic, molecular, or ionic) species. The instrument that performs such measurements is a spectrometer. Spectroscopy is also used in physical and analytical chemistry for the identification of substances through the spectrum emitted from or absorbed by them. The basic principles and methods are well described at Wikipedia and other on-line sources.

There are several application areas where spectroscopic techniques are used. Traditionally it has been mostly found in laboratories at universities and in research intensive industries. However, smaller and lighter instruments have started to find their use also in other areas. This includes Security, Defense, Industrial Q&A, Med-tech and Clean-tech. Considering the size of Serstech’s products, these are also the areas where many of our customers operate.

Various spectroscopic measurement techniques are used depending on the measurement situation. For detection of substances and determination of concentrations, absorption and flourescense spectroscopy of often used. In order to identify chemicals, the use of Raman spectroscopy is becoming increasingly popular. Certain applictions require color detection, which in complex cases rely on spectrometers, but which in many cases can be handed by RGB detectors. You can read more here.
