6. Using PEEK tubing equal to 0.004-inch ID, connect port S of the selector
valve to the ESI probe.
Recommendation:
To reduce peak broadening, use 0.004-inch ID tubing
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).
Warning:
To avoid electric shock, do not use stainless steel tubing
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.
