Abstract
The use of chalcogenide glass for internal reflection spectroscopy (IRS) is described. Chalcogenide glass is a material normally used in infrared fiber-optic systems. A key feature of this concept is the ability to create a tapered section in the IRS crystal in order to increase the interaction with the sample. A liquid cell with integral fiber is described, and its performance as an IRS element is discussed. Several features of the fiber and cell holder are shown to increase sensitivity and allow for an inexpensive sampling accessory.Keywords
