Sample is loaded into the external 20-µL sample loop through the injection port at the front of the valve. The valve has a ceramic stator and PEEK injection seal. PEEK is compatible with pH 0-14, incompatible with some concentrated mineral acids. A make-before-break passage in the stator ensures flow is not interrupted when the valve is switched between the INJECT and LOAD positions, and back again (see also Needles and Flow Connections (G1328C)).
The valve is mounted on a steel mounting pole, and can be installed at the left- or right-hand side of the LC system.
