UTAC-LP1 Ultra Trace Anion Concentrator Low Pressure (4 x 35 mm) | 063079 |
The IonPac? UTAC-LP1 Ultratrace Anion Concentrator Column is a pellicular anion-exchange concentrator column with low void volume (approximately 145 μL). This ultraclean (low sulfate) concentrator column is designed primarily for high purity water analysis. It strips ions from a measured volume of aqueous sample matrix, concentrating the analyte species and lowering detection limits.
-
Low-backpressure column
-
Compatible with the AS40 Autosampler
-
Supports carbonate/bicarbonate, borate, and hydroxide eluents
