With Raman spectroscopy, scientists can measure with exactitude the densities and other attributes of solids, liquids and gases alike. Its applications have demonstrated more and more potential in a growing number of fields. Understanding the TechnologyTouchRaman probes and other tools that use Raman spectroscopy technology gather data about substances at the molecular level. Typically, a monochromatic light is shined upon the object that is being measured. The laser beam will scatter in a unique pattern in accordance with the material it lands on. Observing the scatter enables technicians to map traits of the substance or substances being looked at, their level of density, and other traits. The technique -- which is actually a series of different measuring strategies -- is named after the Raman effect, wherein electromagnetic waves collide with a molecule and interact with its bonds. To start out with, a predictable wave of light is employed, making it possible to interpret the end result. How It Is UsedChemistry is the field in which TouchRaman spectroscopy is most commonly applied because it collects its data from reacting to chemical bonds. However, its applications are wide-ranging. Pharmaceutical researchers use custom instruments such as TouchRaman probes to measure active ingredients in medications, and what form those ingredients take at the molecular scale. TouchRaman instruments such as these can also be key in physics to determine the crystalline state of materials, as well as measure their temperature. Some TouchRaman probes are even able to gather data regarding caustic materials that would ordinarily destroy the measuring tool. Spatially Offset Raman SpectroscopyAnother kind of Raman spectroscopy, known as "spatially offset Raman spectroscopy," is able to ignore surface layers and can be used to, for example, positively identify counterfeit medications without disturbing their containing packages. They can also be used to track changes in biological tissue, in some ways similar to an ultrasound. Research projects are in the making to determine whether various TouchRaman and similar tools can be used to identify the presence of explosive materials at a distance, and even to test whether individual living cells are cancerous, potentially making surgery much less risky and more precise, boosting favorable prognoses considerably. MicrospectroscopyRaman spectroscopy can be used to examine minerals, cells, and forensics evidence on a microscopic level. Lab techs can even use it to determine the amount of cholesterol or other substances in foods. CustomizationWhile manufacturers such as ball probe sometimes sell premade TouchRaman and similar tools to government, academic and pharmaceutical organizations, those manufacturers are also able to customize and construct devices optimally attuned to the measurement and observation requirements of the purchaser.
