Near Infrared (NIR) and Ultraviolet / Visible (UV-VIS) spectroscopy are two common types of spectroscopic techniques used in analytical chemistry and other scientific fields.

NIR spectroscopy is a non-destructive analytical technique that involves the interaction of near-infrared radiation with a sample. The NIR region of the electromagnetic spectrum is located between the visible and mid-infrared regions, and typically ranges from 780 to 2500 nanometers. NIR spectroscopy is used to identify and quantify the presence of different chemical components in a sample, such as moisture, protein, fat, and sugar content in food and agricultural products.

UV-VIS spectroscopy is another non-destructive analytical technique that measures the absorption, transmission or reflectance of ultraviolet and visible light by a sample. The UV region ranges from 200 to 400 nanometers, and the visible region ranges from 400 to 700 nanometers. UV-VIS spectroscopy is commonly used to determine the concentration of a compound in a solution, as well as to characterize electronic and structural properties of molecules.

Powerful Near Infrared (NIR) and Ultraviolet / Visible (UV-VIS) spectroscopic techniques are used in our GUIDED WAVE™ NIR & UV-VIS Process & Lab Analyzers and optical solutions. We deliver a total solution that includes optically matched components and a well-planned calibration approach leading to long-term success and savings. Our state-of-the-art systems are designed for continuous online use, providing real-time data of laboratory quality while thriving in the most demanding processing plant environments. These analyzers are adaptive in nature; meaning that the analyzer can be programmed to measure many different parameters related to many different processes.

Our full-spectrum, extended-range, near-infrared process spectrometer (XNIR, 1000-2100 nm) for a wider range of applications monitor in real-time, in-process measurements for fast, reliable online analysis and monitoring of complex process streams.  The dual-beam design to maximize long-term stability and in-process robustness.
