Replacing The Diverter Valve - Thermo Scientific Dionex UltiMate 3000 Series Operating Instructions Manual

9. Install the diverter valve connections (→ section 3.3.2, page 28). A low-flow inlet
capillary is shipped with the kit.
10. Verify that the alignment is still correct (→ page 44).
Tips: After installing the low-flow inlet capillary, always determine the delay time or
volume. Note that the carry-over volume of the kit for low flow rates is smaller
than with the standard configuration.
Exclusively use the low-flow drop former within the specified flow rates (up to
10 mL/min). At higher flow rates, the jet from the drop former may cause
sprays or spillages.
