Use a needle wash liquid that is suitable for your application and
that removes residual sample from the needle sufficiently.

Check the liquid level of the needle wash reservoir. Fill the needle
wash reservoir with fresh needle wash liquid if required.

wash port with the fresh needle wash liquid. During purging, the
needle wash port and the fluid path is flushed continuously until the
fresh needle wash liquid is present.
