Sample Injection/Wash Port
The Sample Injection/Wash Port (Figure 6 and Figure 7) consists of a waste transfer and
port. After completion of a liquid handling function, the excess sample is discarded in the
waste port. The probe is then moved to the wash port for cleaning. Washing is accomplished
by pumping wash fluid through the probe. The fluid then flows around the outside of the
probe and overflows into the waste port. The waste fluid then travels by gravity out of the
waste tubing to a waste reservoir located below the instrument.

The transfer port is used to transfer the sample to the flowcell located in the sample
compartment of the spectrometer. The transfer port consists of a nylon fitting into which the
sample probe is lowered.
Sampling Probe/Needle
The sample is drawn through the stainless steel needle and delivered to the flowcell via the
transfer port. The needle is cleaned in the wash port: the solvent flows down inside the
needle, and then is forced up around the outside and to waste.
