IonPac anion concentrator columns are designed primarily for high-purity water analysis. The concentrator retains ions from a measured volume of aqueous sample matrix, concentrating the analyte species and lowering detection limits by 2–5 orders of magnitude UTAC-LP1 The UTAC-LP1 Ultra Trace Anion Concentrator Column is a pellicular anion-exchange concentrator with low void volume. The ultraclean (low sulfate) UTAC-LP1 is a general purpose concentrator column for use with syringe or autosampler loading. • Low-backpressure column • Compatible with the AS40 Autosampler • Supports carbonate/bicarbonate, borate, and hydroxide eluents
