Why FTIR?

FTIR is one of the fastest-growing segments of the burgeoning analytical technologies industries. Previously relegated to being tinkered with in atmospheric chemistry laboratories and within research organizations, FTIR gas analysis has come to revolutionize the way science and industry provide vital chemical and environmental data.

FTIR spectrometers are available throughout the world from a number of quality manufacturers in several different countries. Among these manufacturers are PERKIN-ELMER (United Kingdom), BRUKER (Germany), Thermo-Fisher NICOLET, VARIAN Digilab, ABB/Bomem, and MIDAC (United States), also SHIMADZU, JEOL, and JASCO, (Japan) and others. Gemini Spectral Sciences gas sampling accessories are fit to any infrared spectrometer, in order to provide a gas sampling device of the highest quality, performance, and suitability for the users application and technical requirements.

Any FTIR spectrometer used for gas measurements requires a gas sample cell to provide optical transmittance through the sample. It is necessary to provide a cell with specifications appropriate to the unique circumstances determined by each separate application. Measurement sensitivity is determined by trade offs between many factors. Among these are pathlength (base optical path x number of passes), reflectivity, f/number, image size, detector noise and spectral resolution. To cope with an increasingly demanding need for an analytical accuracy, speed, and specificity, simple and effective solutions are provided to meet a wide range of user needs.
