Ultratrace Determination of Uranium(VI) in Drinking Water by Adsorptive Stripping Voltammetry According to DIN 38406-17
3 May 2011The present application poster examines the influence of different components of a sample matrix such as organics, copper and chloride ions in the determination of uranium in mineral and tap water by using a voltammetric technique is. Dissolved uranium(VI) is determined by Adsorptive Cathodic Stripping Voltammetry (AdCSV) down to the ppt level.

ElectrophoresisElectrophoresis equipment is used to separate mixtures of protein, DNA or RNA, based on their electric charge, size and other physical characteristics, by passing them through a medium such as a polyacrylamide gel, an agarose gel or a capillary tube. Electrophoresis equipment includes horizontal and vertical gel electrophoresis chambers, isoelectric focusing systems, 2D electrophoresis and capillary electrophoresis instruments. Precast gels with a gradient can be used or gels can be hand cast. Samples are run alongside ladders or markers to identify the approximate size of a molecule. Separated proteins and nucleic acids in the gel can be stained or probed with fluorescent markers and then imaged and detected using gel documentation instruments, transilluminators, densitometers and scanners.

In a voltammeter the current is measured in the system whilst the voltage is varied. Usually 3 metal electrodes are required including the reference, auxiliary and working electrodes. In polarography, a subclass of voltammetry, the working electrode used is a dropping mercury electrode (DME). The 2 main types of voltammetry are cyclic and linear sweep voltammetry.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.TitrationTitration is an analytical technique for determining substance concentration in a solution. For titration consider a manual or automated system, volumetric or coulometric reagent addition and indication by a potentiometer, spectrometer, turbidometer or by the Karl Fischer method. Other features of titration to consider include burettes, reagents, concentration range, reaction time and autosamplers.
