or stainless steel finger-tight screws to connect the selector valve
to the ESI probe; use the PEEK tubing and natural (beige) colored
PEEK finger-tight screws supplied with the instrument.
6. Using PEEK tubing equal to 0.004-inch ID, connect port S of the selector
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 between the selector valve and the
probe, minimize the length to reduce peak broadening.
• When cutting the tubing to length, cut it squarely (that is,
perpendicular to its horizontal axis).
