HPLC Column Selection

ST flowpath selectors can be used for rapid access of up to six HPLC columns, eliminating instrument downtime involved in exchanging columns and leakage due to repeated changing of tubing fittings. The columns are installed as a part of the loop system, as shown in this drawing.

Sample flows from the injector through the ST valve to the inlet of the selected column, and from the outlet of the column through the valve to the detector.
