Sodium Chloride (NaCl) is a commonly used material in FTIR spectroscopy that is best known as a cost-effective generalist. With excellent transmission over a large range, it is a good option for most FTIR applications. NaCl is sensitive to water and should not be used in samples that contain water. As such, these windows are frequently used in FTIR gas cells. While, Sodium Chloride is sensitive to thermal shocks, it can be used in temperatures up to 400ºC.
