7. Using PEEK tubing greater than or equal to 0.004-inch ID, connect port
2 (the top port) of the diverter valve to the ESI probe.
Recommendation:
for sample flow rates ≤1.2 mL/min; use 0.005-inch ID tubing for sample
flow rates >1.2 mL/min.
Requirements:
• If you are replacing the tubing supplied with the instrument, you
must minimize the length of the tube connecting the diverter valve
to the ESI probe. Doing so minimizes delays and dispersion.
• When cutting the tubing to length, cut it squarely (that is,
perpendicular to its horizontal axis).
Tubing connection between the diverter valve and the ESI probe:
The other plumbing connections are omitted for clarity.
Tip:
Caution:
become trapped when closing the access door to the fluidics valve.
