Heated Variable Path Length FTIR Sealed Liquid Cell

International Crystal Laboratories (USA) new heated variable path length cell can be heated to 200° C and comes complete with a programmable temperature controller with RS-232 serial cable computer interface. The cell back plate is water cooled and the body is insulated as is the vernier scale adjustment on the front of the cell to enable in-situ variation of path length while the cell is situated in the sample compartment of an FTIR spectrophotometer. The path length may be continuously adjusted from 0.05mm to 5mm and reproduced within 0.001mm (1 micrometer). In order for weaker absorption bands of many liquids to appear with the proper intensity, the stronger bands will be totally absorbed and their exact location thus obscured. The Variable Pathlength Cell may be precisely adjusted to provide just the right intensity for exact location of both weak and strong bands.
