FTIR accessories: liquid cells

Liquids are analysed in transmission cells as a thin film between two IR windows. The choice of IR window material and path length is determined by the sample type and application. The sample is analysed neat or dissolved in a suitable solvent. For quantitative analysis, sealed liquid cells with known path length are available.

When selecting IR cell windows, optical (transmission range), chemical and mechanical properties have to be taken into account. We provide both round and square IR windows in all common materials.

Due to the hygroscopic nature of the materials of many IR cell windows and other accessories, storage in a dry atmosphere, such as a drying cabinet, is re commended.
