The simplest and most versatile IR cell system available anywhere

A universal transmission cell for the analysis of liquids and mulls in FTIR and dispersive IR spectroscopy

Cat. No. GS-1800

Features:

• Quick to assemble and change windows
• Windows and spacers compatible with older cells
• FTIR and dispersive compatibility
• Low cost and reliable

The Omni-Cell System is a novel approach to the analysis of liquid samples in transmission spectroscopy - one cell is suitable for all applications. The demountable version is a general-purpose cell for all liquids. It has the advantage of being easy to dismantle for cleaning, and for changing windows and spacers.

The cells are compatible wlith all FTIR Spectrometers, as well as older dispersive systems. They can be configured easily for use as demountable liquid cells, permanently sealed liquid cells, or as mull cells.

Transmission is well established as a technique for analyzing samples in infrared. The choice of window material, pathlength, and window configuration are determined by the sample and wavelength range of interest.

Samples can be analyzed neat or diluted with an appropriate solvent. FOr quantitative analysis, the sample is often analyzed in a cell with a known pathlength. A guide to the selection of the correct pathlength for various concentration is shown opposite.

Solid samples can be analyzed using the mull technique. The solid is mixed with a mulling agent, such as Nujol, to form a mull. The mull is then analyzed between circular windows.
