美国戴安Dionex UTAC-LP2 Ultra Trace Columns 戴安色谱柱 079917 离子色谱柱

The IonPac^® UTAC-LP2 Ultratrace Anion Concentrator Column is an 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. Backpressure resilience has been improved to eliminate the need for a pulse damper on the loading pump, and matrix resilience has been improved to allow direct injection of samples containing polyacrylic acid additives.

• Low-backpressure
• Compatible with the AS-DV Autosampler, and Loading Pumps
• Ultraclean (low sulfate)
• Supports carbonate/bicarbonate, borate, and hydroxide eluents
