Transmission remains one of the most sensitive methods used in mid-IR spectroscopy. However, correct sample thickness is essential for obtaining good spectra. The wide range of sampling accessories has been designed for the comprehensive analysis of gases, liquids and solid samples. For gas analysis, pathlengths range from 5 cm up to 20 m for ppm sensitivity. Various cell and window designs are available for the measurement of aqueous and non-aqueous liquids. Films and other solids are measured using film holders, KBr pellet presses and other accessories designed for the transmission of light through a prepared sample.
