With Raman spectroscopy, laboratory technicians with very little training can measure, with a lot of precision, the concentration levels and other attributes of solids, liquids and gases alike. Its potential uses have demonstrated an increasing amount of potential in an optimistic number of industries. How It WorksTouchRaman probes and other tools that use Raman spectroscopy technology gather information about elements at the micron level. Usually, a laser is focused upon the subject material. The laser beam will scatter uniquely depending on the substance it hits. Observing the scatter enables scientists to identify the substance or substances being observed, their degree of density, and other properties. The technique -- which is actually a series of slightly varying measuring approaches -- is named after the Raman effect, which is where electromagnetic waves hit a molecule and affect its bonds. In this case, a predictable wave of light is used, making it possible to interpret the outcome. How It Is UsedThe most common application of TouchRaman spectroscopy is in the field of chemistry because it collects its data from reacting to chemical bonds. However, its uses are wide-ranging. In the pharmaceutical field, specialized tools like TouchRaman probes are used to identify active ingredients in medications, and which form those ingredients take at the molecular level. TouchRaman instruments like these can also be useful in physics experiments to determine the molecular state of substances, as well as measure their temperature. Some TouchRaman probes are even capable of compiling details about corrosive substances that would ordinarily do damage to the measuring device. Spatially Offset Raman SpectroscopyAnother type of Raman spectroscopy, called "spatially offset Raman spectroscopy," is capable of ignoring surface layers and can be used to, for instance, identify counterfeit medications without opening their containers. They can also be utilized to monitor biological cells, like an ultrasound. Research projects are under way to determine whether different TouchRaman and similar probes can be utilized to find explosive substances from a distance, and even to ascertain whether individual living cells are cancerous, potentially making surgery substantially less risky and more precise, boosting favorable prognoses. MicrospectroscopyRaman spectroscopy can be utilized to look at polymers, cells, and forensics evidence on a microscopic level. Lab techs can even use it to determine the level of cholesterol or other substances in foodstuffs. CustomizationWhile manufacturers such as spectroscopic research sometimes sell ready-made TouchRaman and similar devices to government, academic and pharmaceutical organizations, those manufacturers are also able to specialize and construct devices ideally suited to the measurement and observation needs of the individual order.
