UV-Vis spectroscopy is a technique that scientists use to examine the material through observing the absorption of various light spectrums. Its equipment utilized 2 specific types of light: ultraviolet light and visible light. This, now, is where these types of light become very powerful and crucial in that they allow us to probe the characteristics of different chemicals and materials. This technique allows scientists to learn a host of valuable information.
In order to better grasp the process for how Labtech’s UV-Vis spectroscopy machinery operates, we first need to learn a bit about light. Light has many colors, and they coexist a range of wavelengths. Wavelengths, like the heights of ocean waves, can be measured with specialized scientific equipment which can locate what points are being measured. When light hits a sample—either a liquid or a solid—part of the light is absorbed by the sample and part passes through it.
One important application for UV-Vis spectroscopy is for quantitative measurements of the amount of a particular analyte in a sample. Quantitative analysis is the name of this measure. When scientists want to obtain a precise measurement of a chemical in a liquid solution, quantitative analysis becomes particularly important.
Labtech: A good tool for this job is the UV-Vis spectroscopy equipment (Labtech) which can detect really low amount of chemicals in the sample. It does this by shining a beam of UV or visible light at the sample, and then measuring the resulting absorption of light. The equipment gathers this data and uses it to aid scientists in determining the concentration of the chemical they are testing in the sample.
Labtech's UV-Vis spectroscopy equipment can also be used to investigate the behavior of specific substances, with both liquid and solid samples in bulk. It is capable to analyze, for example, the color of the material or whether impurities (unwanted substances that could compromise the quality of the sample under study) exist.
When scientists analyze a sample with UV-Vis spectroscopy equipment, they take note of what wavelengths of light the sample absorbs. Different chemicals will absorb different wavelengths of light, and this information can provide scientists significant clues about what is contained in the sample they are measuring.
Labtech has a wide range of standard UV-Vis spectroscopy equipment and many of them are configurable to suit the specific user needs. For instance, a scientist may want to analyze samples that cover a wide range of wavelengths, and therefore select a machine that is capable of a larger wavelength range. If on the other hand they are looking for detection of very small amounts of a chemical, they'd want a machine that has a very sensitive detector.
