2. Place the film onto the Film Holder and slide the Film Holder into the OMNI-Transmission
accessory. Slide the Cell Slot #1. Refer to the "Accessory placement table" for proper ori-
entation.
3. When purging the accessory, place the OMNI-Transmission accessory Well Cover over the
Film Holder and allow two minutes or less for the purge to eliminate carbon dioxide and water
vapor inside the sample compartment.
4. Measure the sample.
Analyzing liquids
A variety of infrared transmission cells are available to carry out routine and qualitative analyses
of liquids. Cell choice greatly depends on several factors associated with sample materials;
viscosity, concentration, volume, absorbance values, ease-of-use and/or analytical methods.
Precise or elongated pathlengths increase infrared sensitivity for more qualitative studies.
Cells ideal for highly accurate quantitative analyses of liquids are:
• Cavity Cell Holder (P/N FT04-033)
• Sealed Cell (P/N FT04-035)
• 10mm Pathlength Demountable Liquid Cell (P/N 0004-###)
• 25mm Pathlength Demountable Liquid Cell (P/N 0004-###)
• 50mm Pathlength Demountable Liquid Cell (P/N 0004-###)
Cells ideal for routine analyses of liquids are:
• Demountable Cell (P/N FT04-036)
• Bolt Down Holder (P/N FT04-060)
• EZ-Fill Bolt Down Holder (P/N FT54-019)
• EZ-Flow Cell (P/N FT64-029)
