30 May 2013: Thermo Fisher Scientific is pleased to announce a new technical note on fast separations in a carbonated beverage using increased flow rates on our high-pressure capillary Ion Chromatography (IC) system, the Thermo Scientific Dionex ICS-5000+ Reagent Free HPIC system. Technical Note 118: Fast Separations of Anions and Organic Acids in a Carbonated Beverage Using High-Pressure Capillary IC describes the determinations of organic acids in these carbonated beverages. The beverage industry uses these acidulants and flavoring agents to maintain beverage freshness, to minimize microbiological growth and to add a characteristic flavor.
With the upgrade to high pressure, capillary systems can operate at system pressures up to 5000 psi. This advance in technology allows 2X to 3X the µL/min flow rates with all the same advantages as standard pressure capillary IC system, resulting in low consumption of water (30 to 40 mL/d of water) and low waste generation. Capillary IC systems can remain on 24/7 with minimal resource consumption which translates into a system which has greater ease-of-use, a longer lasting eluent generator cartridge and a far more inexpensive cost of ownership associated with it.
