Chemical resistance of the single-reflection and multi-reflection ATR PRO400 FTIR accessories

3 and 2 types of prism are respectively available for a single reflectance ATR attachment (ATR PRO400-S) and for a multi reflectance ATR attachment (ATR PRO400-M). They are selected depending on the sample shape, the property and the measurement purpose. With solid samples, the sample shape and the measurement purpose are mainly considered. With liquid sample, its acid resistance, alkali resistance and organic solvent resistance need to be taken into consideration.
