TOC Determination in Phosphoric Acid by UV Digestion
20 Feb 2019Phosphoric acid is used in many industries, for example, in the production of fertilizers and detergents or in food industries as a preservative in beverages or as an antioxidant in meat products. The monitoring of impurities in phosphoric acid is crucial for these kinds of applications. In addition to other parameters, the TOC is used as a sum parameter in quality control that addresses the whole range of contamination by organic impurities.

UV-Visible SpectroscopyUltraviolet-visible (UV-Vis) spectrophotometers are used to measure the interaction of UV and visible light with a sample, including transmission, reflectance & absorbance. The two major instrument classes are single-beam or double-beam spectrophotometers. More specialized equipment includes colorimeters, spectroradiometers and refractometers. Portable and microvolume spectrophotometers are also available. For the modular spectroscopy lab, explore a range of light sources for combination with a spectrograph/spectrometer and optics.
