Abstract
An HPLC injection valve is mounted to a probe drive system close to the probe axis to minimize probe movements required for sample injections into a mobile phase column. The probe is directly connected by a short conduit to the injection valve, eliminating the need to dispense aspirated samples from the probe into a remote injection port.
