Achieve high-efficiency separations of hydrophobic, ionizable compounds with these polymeric-based, reversed-phase columns.
For high-resolution separation of free amino acids by the Dionex™ AAA-Direct™ system, choose this pellicular ion-exchange column with no need for derivatization.
Resolve a large number of inorganic anions and organic acid anions in complex matrices.
Low capacity cation-exchange column for gradient separation of polyvalent and moderately hydrophobic amines in complex matrices using aqueous eluents and elevated temperature.
Use this general purpose, low-dead-volume anion concentrator column to maximize the number of injections between eluent changes when using an RFIC™-ER system.
Use this high capacity anion trap column to strip anionic contaminants from deionized water or RFIC-EG eluents to prevent them from reaching the guard or analytical column.
Choose from low, ultralow, and extremely low pressure formats with improved backpressures to concentrate anions for trace-level analysis of high-purity water.
High capacity, anion-exchange column that uses an isocratic carbonate/bicarbonate eluent for analysis of trace bromate and other oxyhalides in diverse environmental samples.
Determine disparate concentration ratios of sodium and ammonium in diverse sample matrices using an isocratic eluent with this very high capacity cation exchange column.
Measure trace bromate and other oxyhalides in drinking water, ground water, wastewater, and other diverse sample matrices.
Order newer Thermo Scientific™ Dionex™ IonPac™ AS22 column as substitute. This column is available only in limited quantities for customers with established validated methods.
For isocratic determinations of linear polysaccharides and mono- and disaccharides in a variety of matrices, use Thermo Scientific™ Dionex™ CarboPac™ PA1 Analytical & Guard Columns.
Choose from low, ultralow and extremely low pressure formats to concentrate cations for trace-level analysis of high-purity water.
Medium capacity anion-exchange column using a carbonate/bicarbonate eluent for super fast separation of common inorganic anions for compliance monitoring in diverse matrices.
For nonsuppressed conductivity detection or single-column ion chromatography (SCIC), choose this silica cation separatorcolumn.
