This is the third and last blog post in the series of posts on the advantages of the newly introduced Capillary Ion chromatography (IC) over IC in water analysis, pharmaceutical applications, and food testing market. Our application lab in Sunnyvale has been very busy updating some of the existing IC methods on capillary IC and we recently released a number of these application notes for a number of different markets.
The key benefit of Capillary IC is that it helps chemists save time, labor, and reduce operating cost, while increasing the productivity and reproducibility of ion analysis. How? Since the system operates at such low flow rates (~10 µl/min), it is practical to operate a Capillary IC 24/7, so the system is ready to run samples at any time! Also, the Eluent Generator module (EG) is able to produce eluent automatically from deionized water for up to 18 months under continuous operation, making gradient separations as easy as isocratic.
Here we present three applications for the fast analysis of water analysis.
Application Cost-Effective Determination of Inorganic Anions and Cations in Municipal Drinking Water Using Capillary Ion Chromatography discusses how the Capillary IC system can be operated continuously, reducing eluent preparation, system start up, and equilibration times, and requiring less frequent calibrations. This provides significant cost savings for drinking water analysis.
Application Capillary Ion Chromatography Mass Spectrometry for Trace Environmental Analysis discusses how using Capillary IC in conjunction with the optimized ESI source can result in successful applications for trace level environmental analysis, including common anions and organic acids, perchlorate, and residue of the herbicide endothall in environmental water samples.

Application Hexavalent Chromium Determination by Two-Dimensional Capillary Ion Chromatography Using a Monolith Concentrator Column describes a two-dimensional method for hexavalent chromium determination in drinking water samples using suppressed conductivity detection. It shows how combining standard-bore and capillary columns can yield minimum detection limits (MDLs) better than existing methods.
