Use of an infrared spectrophotometer in good operating condition does not in itself assure accurate results. The validity of the spectra also depends on the sample-handling techniques, which will be discussed in Chapter 7, and on the selection of proper instrument operating variables, which is a primary concern of this chapter. To aid in understanding the operating variables and their interrelations we shall first examine the basis of operation of one type of widely used infrared spectrophotometer. This will be followed by a discussion of the operating variables and their qualitative and quantitative interdependence. The remainder of the chapter will describe the components and features of infrared spectrophotometers.
