Columns to Capture and Concentrate Sample Ions from Large Injection Volumes

IonPac^® and IonSwift™ concentrator columns are designed primarily for high purity water analysis. A concentrator column retains ions from a measured volume of aqueous sample matrix, concentrating the analyte species and lowering detection limits. Concentrator columns typically have internal volumes of hundreds of microliters, but can concentrate the ions from tens of milliliters, increasing sensitivity by 2–5 orders of magnitude compared to standard sample loops.
