The UTAC-ULP1 Ultratrace Anion Concentrator Column is designed primarily for high purity water analysis.  The UTAC-ULP1 strips ions from a measured volume of aqueous sample matrix, concentrating the analyte species thereby lowering detection limits.  The UTAC-ULP1 is an ultra clean (low sulfate), concentrator column.  The UTAC-ULP1 is a general purpose concentrator for use with syringe or autosampler loading.  The UTAC-LP1 (4 x 35 mm) is an ultra low backpressure column and can be used with the AS40, AS50, or AS Autosamplers.  The UTAC-ULP1 (5 x 23 mm) Concentrator Columns can be used with single piston sample delivery pumps including the DXP-1 and DQP pumps.  The UTAC-ULP1 can be used with carbonate/bicarbonate, borate, and hydroxide eluents. The UTAC-ULP1 has a capacity of 25.0 µeq/column and a void volume of approximately 145 µL. The UTAC-ULP1 is available in 5 x 23 mm format.
