ion chromatography analysis of juicesThis is the second blog post in the series of posts on the advantages of our newly introduced Capillary Ion chromatography (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 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 three recently released application briefs for the analysis of juices and coffee using Capillary IC.

  • capilliary ion chromatography separation of inorganic anions and organic acid anions in coffeeApplication Brief 135, Determination of Anions and Organic Acids in Brewed Coffee Samples Using Capillary IC (downloadable PDF) describes the separation of inorganic anions and organic acid anions in caffeinated and decaffeinated brewed coffee samples within 20 min using a capillary IC system. This analysis is designed to monitor coffee maturation, ensure coffee bean quality, and to determine extent of adulteration in purchased beans.
