In the 1980s, Karl Norris (while working at the USDA Instrumentation Research Laboratory, Beltsville, USA) pioneered the use NIR spectroscopy for quality assessments of agricultural products. Since then, use has expanded from food and agricultural to chemical, polymer, and petroleum industries; pharmaceutical industry; biomedical sciences; and environmental analysis.


Near-infrared spectroscopy (NIRS) is a spectroscopic method that uses the near-infrared region of the electromagnetic spectrum (from 780 nm to 2500 nm). Typical applications include medical and physiological diagnostics and research including blood sugar, pulse oximetry, functional neuroimaging, sports medicine, elite sports training, ergonomics, rehabilitation, neonatal research, brain-computer interface, urology (bladder contraction), and neurology (neurovascular coupling). There are also applications in other areas as well such as pharmaceutical, food and agrochemical quality control, atmospheric chemistry, combustion research and astronomy.


SRC, in its quest to provide leading-edge technologies to potentiate the R&D capabilities of the Canadian scientific community, has recently integrated NIR Spectroscopy technologies into its portfolio from a profound manufacturer like Speaac Ltd.

  • Specac’s ProCell™ Vortex, Flange-Mounted NIR Liquid Process Cell, is a robust flange-mounted liquid transmission cell for in-situ monitoring of industrial process streams by UV/Vis and NIR optical spectroscopy via the use of optical fibers. It is designed to be installed either directly on a process plant or in a short by-pass loop. To ensure ease of process integration, the cell can be configured from a wide range of ANSI and DIN flange sizes. The cell is easily trace-heated and insulated for use at elevated temperatures, and cleaning ports can be added to facilitate in-situ cleaning of the windows.

  • Typhoon NIR Vapour Flow Cell is designed for the online measurement of the spectra of process gases and vapours using fiber optics. The Typhoon gas cell is installed on fast by-pass loops directly on the plant, which allows for real-time remote monitoring and control. Superior optical design, state-of-the-art sealing technology and rugged construction are combined with precision manufacturing to ensure many years of reliable, high performance.
