Development of On-Site Measurement of Calcium in Food Samples by Use of Ion Selective Electrode
26 Jul 2015Laboratory based measurements of concentrations of calcium in food samples are commonly made using Inductively Coupled Plasma (ICP), Ion Chromatography (IC) and Atomic Absorption Spectrophotometry (AAS). On-site measurements cannot be made using such equipment due to due the size and bulk of such instruments, therefore Horiba Scientific’s B-751 LAQUAtwin Compact Calcium Ion Meter is considered a new proposed method for such applications. This application note proposes a new measurement method which dissociates the compound including calcium into the calcium ion adjusting pH of samples before the potentiometric measurement with the compact calcium ion meter (abbreviated as Ca2+-meter).

Ion ChromatographyIon chromatography, also known as ion exchange chromatography, is a high-performance liquid chromatographic technique used for the separation and identification of ions or polar molecules in a sample, including proteins, nucleotides and amino acids. Equipment includes ion exchange columns, ion exclusion columns, ion chromatography systems, pumps, and detectors. Find the best ion chromatography equipment 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.Food and Beverage AnalyzersFood and Beverage Analyzers are commonly used to provide information about the chemical composition, structure and physical properties of food materials.CalciumFood TestingFood testing refers to a variety experiments including PCR, mass spectrometry, processing, QuEChERS, analyzing and Kjeldahl.Ion Separation
