Chemical analysis is an established scientific approach that makes it possible to identify and quantify elements that make up a material. Therefore, chemical analysis is a function of technique, instrumentation, and application. It also involves the breakdown of molecular structures and the examination of atomic energy levels. Chemical analysis using a spectrometer is a relative technique, using calibration to convert the instrument from a light measuring device to a chemical analysis instrument. The focus of this discussion is on atomic spectroscopy as it is applicable to agrochemicals. Three modes of detection are highlighted: absorption spectrum, emission spectrum, and mass spectrum.
