Abstract

A large number of infrared cells have been used in adsorption studies on supported metal samples. Description of these cells and their construction are available in the open spectroscopic literature. In general, an infrared cell is designed and constructed with a particular application in mind; however, most designs must conform to the following requirements: (1) they must be vacuum tight at pressures of 10⁻⁶ Torr; (2) they should be readily removable from the path of the infrared beam; (3) they should be provided with a furnace so that the sample can be suitably pretreated before an adsorption experiment; and (4) they should be equipped with an inlet and outlet for the handling of gases.
