This is the first 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 are two recently released application notes for pharmaceutical analysis using Capillary IC.
Application Implementation of a Walk-Up High-Pressure Capillary Ion Chromatograph for the Fast Separation of Pharmaceutically Relevant Inorganic Anions and Cations discusses the determination of inorganic anions and cations in two different drugs using a capillary IC system. The note highlights how the reagent-free capillary systems reduce eluent preparation, system start up time, and equilibration time, and require less frequent calibrations.
