IonPac and IonSwift concentrator columns for anion, cation, and chelation ion chromatography are used to concentrate analytes, allowing determinations at µg/ (ppb) and sub-µg/ levels. IonPac trap columns for anion and cation determinations prevent eluent contaminants from causing interfering peaks during gradient ion chromatography. Columns IonPac Columns are designed primarily for high-purity water analysis. The columns retain ions from a measured volume of aqueous sample matrix, thereby concentrating the analyte species and lowering detection limits. The advantage of using concentrator columns is the ability to perform routine analysis for ions at µg/ (ppb) to ng/ (ppt) levels. Figure illustrates a typical IC trace-enrichment system configuration using a concentrator column. The sample is pumped across the concentrator column, as shown in Figure A. After the analytes from the sample are concentrated, the valve is switched. The concentrated analytes are then swept by the eluent from the concentrator column onto the analytical column, as shown in Figure B. Figure illustrates the configuration of a D-IC System using a capillary concentrator column. The concentrator column is placed between the first and second dimension of the D System setup; a cut volume then is focused on the capillary concentration column, then eluted onto a second dimension column. Passion. Power. Productivity.

2 Figures illustrate the use of this system configuration for trace-level anion determinations. This concentrator system can also be used for the determination of trace cations and transition metals, as shown in Figures and.

3 Anion s Anion Micro (AMC-) ( mm)...p/n 7 The AMC- is a low void-volume microconcentrator column designed for the concentration of inorganic and lowmolecular-weight organic anions from ultrapure water.

IonPac Anion for Eluent Regeneration (AC-ER) ( mm)...p/n 7778 The AC-ER ( mm) Anion Column is a general purpose, low-dead volume, extremely low pressure anion concentrator column with similar features to the UTAC concentrators, but with reduced dead volume and capacity. The AC-ER is available in a mm format for very low-dead volume to maximize the number of injections that can be made on an RFIC system with eluent regeneration (ER) between eluent exchanges. The AC-ER has a capacity of. µeq/ column and a void volume of approximately 7 µ. With an AC-ER column installed in an RFIC-ER system, each injection only adds 7 μ of sample matrix into the eluent regardless of the sample volume (7 µ + µ for connecting tubing). Therefore, approximately injections can be performed before the eluent needs to be replaced, regardless of the actual amount of sample loaded onto the concentrator. And by using a matrix elimination step with the AC-ER in place, solvents can be directly injected onto the AC-ER then flushed off before injection into the RFIC-ER system. The new AC-ER concentrator brings a host of new applications within range of RFIC-ER systems, including analysis of bromate to ppb in drinking water, and analysis of common anions in ethanol.

Cation Polisher Columns Cation Polisher CP and CP columns are designed for removal of metallic contaminants and other cations such as calcium and magnesium from the sample stream while performing anion analysis. The columns improve the performance of ion chromatography systems, particularly with phosphate analysis in the presence of metallic contaminants. Samples that contain high levels of metals or cations can be deposited on the guard/analytical columns or the suppressor, which can lead to performance issues such as poor peak shapes or poor recoveries for some anions such as phosphate. These contaminants can adversely affect the operation of the guard/analytical columns or suppressor. Cation Polisher columns address the potential precipitation issue of these contaminants and aid in extending the column and suppressor lifetimes when pursuing anion analysis and when the matrix ions contain multivalent cations. In some cases the Cation Polisher columns aid removal of matrix cations when pursuing anion analysis with sample preconcentration. The matrix cations can elute species of interest from the concentrator column and lead to poor peak shapes and recovery. Removing the matrix cations using Cation Polisher columns helps ensure good chromatographic performance. The CP ( mm) column is a cation-exchange column in the sodium form and packed in a low pressure format and is specifically designed for autosampler operation. The void volume of this column is approximately µ. The CP (9 mm) column is a higher capacity version in the hydronium form and has a void volume of approximately 8 µ. The CP Polisher Column is recommended for large volume sample preconcentration applications using an external pump. Both columns can be regenerated offline approximately every months (depending on the level of contamination and usage). Cation Polisher CP Na + Form ( mm)...
