Shimadzu, 202-32001-30, Liquid Cell Kit, KRS-5 Windows, Adjustable PL, FTIR

The KRS-5 sealed liquid cell kit is an FTIR transmission accessory for examining liquid samples using infrared-transparent KRS-5 window plates. Its sealed-cell design supports injection and withdrawal of liquid with a syringe and is especially useful for volatile liquid samples. Optical path length is selected by installing an appropriate spacer between the window plates during assembly, rather than by a continuously adjustable micrometer mechanism. This distinguishes the kit from fixed-thickness sealed cells and from demountable cells designed primarily for films, mulls or less volatile samples. The supplied hardware includes a pair of KRS-5 plates with the required holder and sealing components. Path length should be selected based on sample concentration and infrared absorption to avoid saturated bands. Use chemically compatible solvents, prevent abrasive contact with optical surfaces and follow appropriate safety procedures when handling KRS-5 materials. This accessory is a liquid cell assembly for a compatible FTIR sample compartment, not a complete FTIR spectrometer.
