Answer:It is the UTAC-ULP1 ultralow-pressure concentrator format.
Answer:The column measures 5 mm internal diameter × 23 mm long.
Answer:The concentrator has a capacity of 25.0 µeq per column.
Dionex™ IonPac™ UTAC-ULP1 is an ultratrace anion concentrator used to preconcentrate anions before ion-chromatographic separation. This configuration measures 5 × 23 mm and uses a low-void-volume pellicular anion-exchange bed for high-purity water applications. The column has an approximate void volume of 145 µL and a capacity of 25.0 µeq per column, supporting trace-level work where larger sample volumes are concentrated before injection onto the analytical column. Its low-pressure format is useful in automated preconcentration setups and water-monitoring systems that require improved detection limits for ionic contaminants. The concentrator should be integrated into an IC method that is validated for the sample volume, transfer conditions and target anions. The concentrator is not a substitute for the analytical separator; it performs a sample-enrichment step before the retained ions are transferred to the separation column. This makes it especially useful when direct injection cannot provide the sensitivity required for ultratrace water analysis.
