The IonPac TCC-XLP1 (6 × 16 mm) Extremely-Low Pressure Trace Cation Concentrator Column is designed primarily for high purity water analysis. The general purpose column strips ions from a measured volume of aqueous sample matrix, concentrating the analyte species thereby lowering detection limits. The TCC-XLP1 is compatible with a syringe or autosampler (AS40, AS50 or AS Autosamplers) and with single-piston sample delivery pumps including the DXP-1 and DQP pumps. It is recommended for use with carboxylated columns such as the IonPac CS12, CS12A, CS14, CS15, CS16, CS17, and CS18 columns. The column is used with sulfuric acid, methanesulfonic acid, and hydrochloric acid eluents. It has a capacity of 260 µeq/column and a void volume of approximately 145 µL.
