Dionex IonPac SCS 1 Silica Cation Separation Column is a unique hydrophobic, low capacity, weak cation exchange column for cations using non-suppression conductivity detection Assay design. Its base is silica-based poly(butadiene-maleic acid) with a particle size of 4.5 μm. The base microspheres are coated with a coating with unique carboxylic acid functional groups. Dionex IonPac SCS 1 columns can be used with eluents with pH values in the range 2–7 and are compatible with typical organic solvents (such as acetonitrile and acetone) up to 100% concentration. Note: Alcohols should be avoided.

Determination of trace ammonium ions in high-concentration sodium ion samples

Dionex IonPac CS16 column is equipped with suppressed conductivity detection and is recommended for large concentration ratios of sodium and ammonium ions. Dionex IonPac SCS 1 columns can be used for compliance monitoring of alkali and alkaline earth metal cations as well as ammonium ions in water and wastewater.

Measurement of alkanolamines and common inorganic cations in chemical processing solutions

Dionex IonPac SCS 1 column has unique selectivity for alkanolamines and therefore Can be used to resolve the major amines in these detergents using 3mM MSA eluent at elevated temperatures.

Available in a variety of specifications for application flexibility

• 4x250mm, 2x250mm analytical columns
• 4x50mm, 2x50mm guard columns
• Smaller column diameter provides higher mass sensitivity, saving eluent and reagents, thereby reducing operating costs
