Tunable Filter Spectroscopy Analyzer

Stolway AP5 Analyzer is a game-changing analytical instrument that utilizes advanced TFS technology to provide precise and reliable measurements across a diverse range of applications.

Stolway -AP5 analyzer measurement principle is based on advanced spectral decomposition analysis using NIR/IR absorption spectroscopy. This technique relies on the fact that molecules absorb light radiation at certain frequencies or wavelengths, creating an absorption spectrum unique to each hydrocarbon compound.

This spectrum acts as a “fingerprint” and can be used to identify and quantify the compounds present in a sample. The intensity of the absorption is directly proportional to the concentration of the molecules, allowing the Stolway-AP5 analyzer to accurately compute concentrations of hydrocarbon compounds with a high degree of precision and repeatability.
