CE solutions – the alternative for ionsCapillary electrophoresis is a true alternative to ion chromatography.Its main features include:• unmatched analysis time—enhancing your sample throughput• high resolving power—allowing analysis of complex samples in one run• typically < 1 ml of solvent required with only a small amount of waste— savingmoney and helping to protect the environment• no need for specialized columns, precolumns and membranes—easy instrumentsetup and maintenance• often no laborious sample preparation needed—just sample dilution• only nanoliter amounts of samples injected—allowing different methodsor analytical techniques to be applied to one sampleAbsorbance [mAU]Ionic contamination in primary andsecondary circuit water leading to metalcorrosion, is a major problem for thenuclear power generating industry.For this reason low levels of smallanions and cations must be monitored.CE provides a rapid and facile methodfor their determination in the lowppb range.Bromide ChlorideSulfateOxalate Nitrate NitriteChlorateFluorideFormate3 4 5 6 7 8 9Time [min]ChecklistPhosphateþ Ease of sample preparationþ Low sample consumptionþ Fast separationþ Minimal maintenanceþ Low cost of ownershipþ Low ppb sensitivityAcetatePower plantsAbsorbance [mAU]2.521.510.50-0.5ChlorideSulfateNitriteNitrate2 2.5 3 3.5 4 4.5Time [min](Data kindly provided bt Thomas Ehmann,Wacker Siltronic AG, Burghausen, Germany)Semiconductor industry“Capillary electrophoresis, as a microanalytical technique,features merits in the determination of contaminants on wafersurfaces. As the diameter increases, the financial value of thewafers increases exponentially, therefore it is mandatory toapply a great variety of different analysis techniques whenworking on one single wafer. This is possible with CE dueto the low sample volume. Moreover, by changing only thecomposition of the electrolyte, a broad variety of analytesin different matrices can be determined.CE covers a range from ionic to non-ionic analytes that areimportant in the semiconductor industry.”OxalateCitrateDr. Laszlo Fabry(Wacker Siltronic AG, Germany)FluorideFormate
Recycling for cost reduction and environmentalconcerns necessitates themonitoring of Kraft liquors for anioniccontent. The caustic nature of thesamples results in labor intensive maintenanceprocedures. CE analyses are threetimes faster and require minimal samplepreparation compared to ion chromatography.S 2O 32-Cl - SO 42-Green liquor,1:200 dilution in water2 2.5 3(Data kindly provided by Dwayne Van,Longview Fibre, Longview WA, USA)Pulp and paper industryS 2- SO 32-Time [min]Plating bath industry"In the plating bath industry, the monitoring of additives in bathsolutions or waste is essential for quality control and costsaving.
