Raman spectroscopy is a measurement tool that has shown a lot of potential in a lot of new industries and shown a lot of promise in a vast number of scientific endeavors. Understanding the TechnologyHigh-sensitivity Raman measurement tools gather data about elements at the micron scale. Usually, a laser is shined upon the subject material. The laser beam will refract uniquely depending on the material it lands on. Measuring the scatter makes it possible to identify the substance or substances being observed, their degree of concentration, and other traits. The technique -- which is actually a series of closely related measurement strategies -- is named after the Raman effect, which is where electromagnetic waves hit a molecule and affect its bonds. To start out with, a monochromatic wave of light is applied, making it possible to interpret the end result. ApplicationsChemistry is the field in which TouchRaman spectroscopy is most often applied because it gathers its information from interacting with chemical bonds. However, its uses are wide-ranging. In the pharmaceutical industry, specialized tools such as TouchRaman probes are used to identify active components in medications, and the form those ingredients have at the molecular scale. TouchRaman instruments such as these can also be key in physics to determine the crystalline state of substances, as well as measure their temperature. Some TouchRaman probes are even able to compile details about corrosive substances that would ordinarily damage the measuring device. Spatially Offset Raman SpectroscopyAnother type of Raman spectroscopy, known as "spatially offset Raman spectroscopy," is able to ignore surface layers and can be utilized to, for example, identify counterfeit medications without disturbing their containing packages. They can also be employed to monitor biological cells, like an ultrasound. Experiments are in progress to see if various TouchRaman and similar tools can be employed to identify the presence of explosive substances from a distance, and even to discern whether individual living cells are cancerous, potentially making surgery considerably safer and more precise, boosting favorable prognoses considerably. MicrospectroscopyRaman spectroscopy can be employed to examine minerals, cells, and forensics evidence on a microscopic level. It can even be used to measure the amount of cholesterol or other substances in foods. CustomizationWhile manufacturers such as UV spectroscopy sometimes sell premade TouchRaman and similar devices to government, academic and pharmaceutical organizations, those manufacturers are also able to customize and build instruments perfectly attuned to the measurement and observation requirements of the individual order.
