...it was seen as a revolutionary technique. Now, it's fulfilling a role as a well-established technique in analytical laboratories worldwide. CE offers highly efficient separations, short analysis times, and minimal solvent and reagent consumption, when compared with other separation techniques. In fact, CE should be considered first when dealing with highly polar, charged or chiral analytes.

Anions and cations are charged polar species that lend themselves well to the CE format. The most robust ion analysis CE methods use bare fused-silica capillaries with a dynamic coating technology to modulate the electroosmotic flow. Since many small molecules do not absorb UV light, the primary mode of detection is indirect, in which a UV-absorbing chromophore is added to the background electrolyte, the displacement of which provides the basis for detection.

Whether you apply capillary electrophoresis to counter-ion, beverage or industrial applications, you will find that CE with our ion analysis kits provides robust analyses even when handling diverse sample matrices. Only a small sample amount is needed and generally little sample preparation is required. Separations are fast and efficient.

Ion Analysis Kits
Beckman Coulter offers both an anion and a cation analysis kit. Each kit yields approximately 500 tests.

Our ion analysis kits are designed for ion concentrations in the 1-100 ppm range. Sensitivities below that are possible under special circumstances only. Typically a %CV of 1% or less is expected for migration time. For further information, also see our Ion Analysis Data Sheet.

Kits contain Analis Double Dynamic Coating Technology.
