Raman spectroscopy is a technology that has made its way into an exciting number of new industries and shed promising light on a vast number of scientific questions. Understanding the TechnologyHighly sensitive Raman measuring devices gather information about substances at the molecular scope. Generally, a laser is shined upon the material that is being measured. The laser beam will scatter in a unique pattern depending on the material it lands on. Measuring the scatter pattern makes it possible to identify 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 so called because of the Raman effect, which is where electromagnetic waves collide with a molecule and affect its bonds. To start out with, a monochromatic wave of light is used, making it possible to interpret the end result. How It Is UsedTouchRaman spectroscopy is most often utilized in chemistry because it collects its data from interacting with chemical bonds. However, its applications are wide-ranging. Pharmaceutical researchers use specialized tools such as TouchRaman probes to measure active components in drugs, and which form those ingredients take at the molecular level. TouchRaman instruments such as these can also be crucial in physics experiments to determine the molecular state of substances, as well as measure their temperature. Some TouchRaman probes are even capable of gathering information about caustic substances that would normally damage the measuring instrument. Spatially Offset Raman SpectroscopyAnother type of Raman spectroscopy, called "spatially offset Raman spectroscopy," is less sensitive to surface layers and can be employed to, for example, identify counterfeit drugs without opening their containers. They can also be employed to monitor biological cells, like an ultrasound. Experiments are in progress to determine whether various TouchRaman and similar devices can be employed to find explosive substances at a distance, and even to test whether individual cells in the body are cancerous, which could make surgery considerably safer and more precise, boosting favorable prognoses considerably. MicrospectroscopyRaman spectroscopy can be employed to look at minerals, proteins, and forensics evidence on a microscopic level. It can even be used to measure the amount of cholesterol or other substances in foodstuffs. CustomizationWhile manufacturers such as inphotonics raman probe sometimes sell premade TouchRaman and similar devices to government, academic and pharmaceutical organizations, those manufacturers are also able to customize and construct machinery optimally suited to the measurement and observation requirements of the purchaser.
