TOC as Control Parameter for Process Effluents in Starch Production with Multi N/C UV HS
25 Feb 2013The amount of total organic carbon (TOC) in water can be used as a non-specific indicator of water quality. This application note presents a simple, yet robust method using the TOC analyzer multi N/C UV HS from Analytik Jena to measure starch concentrations in effluent water.

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. Find the best UV-Vis spectroscopy products in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Environmental Monitoring and TestingEnvironmental monitoring and testing uses handheld portable analyzers, kits, spectrometers or chromatography systems for air, water, soil, food and other sample testing. Useful features of analyzers such as BOD and COD include portability, easy calibration, automation and sensitivity. Environmental test kits for pH, water, moisture, etc, should be accurate, sensitive, reliable, fast and easy to use.Water AnalysisAnalytical methods used to test the purity of drinking water include determining the level of contaminants abides to the level set by the Environmental Protection Agency (EPA).Waste WaterDrinking Water AnalysisAnalytical methods used to test the purity of drinking water include determining the level of contaminants abides to the level set by the Environmental Protection Agency (EPA).TOC Monitoring
