Beijing Care Corporation Ltd is a leading manufacturer of FT-IR system configured with high quality spectrometer and detector. The gas cell with 10 meter optical length is designed by BCC, the LOD could reach high ppb level. The product has a competitive price with reliable performance. Fourier Transform Infrared Spectroscopy (FTIR) can be widely used. It is a powerful tool for identifying types of chemical bonds in a molecule by producing an infrared absorption spectrum like a molecular "fingerprint". FTIR is most useful for identifying chemicals, organic or inorganic, it can be used to quantitate some components of an unknown mixture and it can also be applied to the analysis of solids, liquids, and gasses. The term Fourier Transform Infrared Spectroscopy (FTIR) refers to a fairly recent development in the manner in which the data is collected and converted from an interference pattern to a spectrum. Today's computerization of FTIR makes them faster and more sensitive than the older dispersive instruments.
