The multichannel analyzer is an important, perhaps the universal, instrument for nuclear chemistry. It can measure complex relationships among radioisotopes, such as relative energy, activity (Sect. 3.2), half-life (Sect. 3.10), abundance (natural isotopic composition), etc., and can present the relationships to the chemist in a variety of ways, depending upon his needs. The measurement results can be displayed as curves on an oscilloscope or recorder, printed as numbers on a digital printer or typewriter, stored on and retrieved from a variety of storage media such as paper or magnetic tape, manipulated arithmetically by an internal calculator, or transferred to a computer for data reduction and report generation (Sect. 12.6.2). Despite this power and versatility, it is an instrument which can be used and understood with little training. For these reasons, multichannel analyzers are found in nearly all nuclear chemistry laboratories and are used for both routine chemical analysis and fundamental research.
