Measurement Precision How TouchRaman Spectroscopy Works

With Raman spectroscopy, laboratory technicians with very little training can measure, with an impressive degree of precision, the concentration levels and other traits of solids, liquids and gases alike. Its potential uses are demonstrating an increasing amount of promise in a growing number of industries. Understanding the TechnologyTouchRaman probes and other devices that use Raman spectroscopy technology gather data about substances at the micron scale. Generally, a monochromatic light is focused upon the material that is being measured. The laser beam will scatter uniquely in accordance with the material it hits. Observing the scatter makes it possible to identify the substance or substances being looked at, their degree of density, and other attributes. The technique -- which is actually a collection of closely related measurement approaches -- is so called because of the Raman effect, wherein electromagnetic waves collide with a molecule and affect its bonds. To start out with, a coherent wave of light is used, making it possible to interpret the outcome. How It Is UsedChemistry is the field in which TouchRaman spectroscopy is most often applied because it collects its data from interacting with chemical bonds. However, its uses are wide-ranging. Pharmaceutical researchers use customized devices such as TouchRaman probes to identify active ingredients in drugs, and what form those ingredients take at the molecular level. TouchRaman devices such as these can also be crucial in physics to determine the molecular structure of materials, as well as measure their temperature. Some TouchRaman probes are even capable of collecting details about caustic materials that would typically destroy the measuring device. Spatially Offset Raman SpectroscopyAnother type of Raman spectroscopy, called "spatially offset Raman spectroscopy," is less sensitive to surface layers and can be used to, for example, notice counterfeit drugs without opening their containing packages. They can also be used to monitor biological tissue, in some ways similar to an ultrasound. Experiments are in progress to determine if various TouchRaman and similar devices can be used to find explosive materials from a distance, and even to check whether individual cells in the body are cancerous, which could make surgery substantially less dangerous and more precise, boosting favorable prognoses considerably. MicrospectroscopyRaman spectroscopy can be used to look at minerals, cells, and forensics evidence on a microscopic level. It can even be used to measure the level of cholesterol or other substances in foodstuffs. CustomizationWhile manufacturers such as inphotonics raman probe sometimes sell premade TouchRaman and similar instruments to pharmaceutical, academic and government laboratories, those manufacturers can also specialize and construct tools ideally attuned to the measurement and observation needs of the purchaser.
