switched into the flow path between detector and needle allowing to
dispense remaining fraction in the needle capillary and needle into the

tube
to increase the recovery of the fraction and reduced carry
over of the first fraction into the second fraction. When flush function is
completed the fraction collection valve will be switched to waste
position until a new fraction collection is triggered.
To remove residual sample from the needle external between runs, the
needle moves to the wash port and descends into it. The needle wash
pump supplies needle wash liquid to the wash port to wash the outer
surface of the needle to the wash waste.
To remove residual fraction from needle internal between runs, the
needle moves to the wash port and descends into it with fraction
collection valve located at collection position. The HPLC pump flow
supplies clean mobile phase to rinse the inner surface of the needle to
the wash waste.
