Spectroscopy is defined as the study of the absorption and emission of light and other radiation by matter as related to the dependence of these processes on the wavelength of the radiation. It is used to study the interaction of spectra of light with matter. Spectroscopy uses instruments such as spectroscopes, spectrometers, spectrographs, spectrophotometers, and so forth for measuring spectral properties and examining spectra. The analysis of the spectra can be used for chemical investigations.
The science of spectroscopy requires an understanding of the electromagnetic spectrum. The electromagnetic spectrum is defined as the total range of wavelengths or frequencies of electromagnetic radiation, extending from the longest radio waves to the shortest-known cosmic rays.
Since the electromagnetic spectrum covers a wide gamut of wavelengths, it is highly studied for spectroscopic uses. The spectrum consists of different types of radiations such as gamma (g), X-ray, ultraviolet, visible, infrared, and radio.
Spectroscopy has its foundation in each element having its own characteristic spectrum. In order to understand various types of spectroscopic instruments and analysis, it is important to discuss different physical quantities that can be measured to determine the unique properties of an element. As with many types of analysis, the quantity measured is either an amount or an intensity of something.
Typically, spectroscopy is distinguished by three types: absorption, emission, and scattering spectroscopy
The science of spectroscopy has diverse applications in industries such as pharmaceutical, biotechnical, chemical, environmental, and food and beverage. Each of these industries involves spectroscopic techniques in different kinds of analysis. Accuracy, precision, and short length of time needed for sample preparation and analysis make spectroscopy technology ideal for routine analysis, as it replaces time-consuming, expensive, and hazardous primary analysis.
The widespread application of spectroscopic techniques in various industries has given impetus to research and development in new technology and instruments. As spectroscopy and its applications are becoming widespread, manufacturers and companies making spectroscopic instruments are fostering new partnerships and expanding into new markets.
Government agencies at various levels play an important role in setting and implementing public safety standards. In the case of spectroscopy and spectroscopic instruments, there are not many regulations that directly affect the sale and manufacturing of these instruments, as they deal only with samples of chemical substances and do not come in direct contact with the public. Nonetheless, government regulations can play a vital part in the use and sales of spectrometers and other spectroscopic equipment.
