Abstract
A sample cell for infrared spectrophotometry comprises a sample holder for holding a sample to be analyzed by infrared spectrophotometry, a cool air passageway and a vortex tube. The sample holder includes a primary optical surface through which infrared radiation is directed to a sample contained in the holder, and the cool air passageway is adjacent the primary optical surface of the sample holder for directing a cool air stream across the primary optical surface. The vortex tube has a cool air outlet connected to the cool air passageway for supplying cool air to the passageway.
