Thermo Fisher Scientific is pleased to announce a new technical note on the fast separations of inorganic ions in saline solution samples.

TN 130: Fast Determinations in Salton Sea Samples Using a High-Pressure IC System demonstrates fast separations of inorganic anions and cations in a Salton Sea surface water sample and a neighboring municipal drinking water sample using ion-exchange chromatography. Monitoring salinity levels in estuarine ecosystems is critical to preventing salinity-specific diseases.

With the upgrade to high pressure, capillary systems can operate at system pressures up to 5000 psi. This advance in technology allows 2× to 3× the µL/min flow rates with all the same advantages as standard pressure capillary IC, 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. This 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.
