4. Slide open the instrument's source interface door (see the figure on
page 3-5).
Warning:
to connect the diverter valve to the APCI probe; use the PEEK™
tubing supplied with the instrument.
5. Using tubing greater than or equal to 0.004-inch ID, connect port 2 (the
top port) of the diverter valve to the APCI probe.
Recommendation:
for sample flow rates ≤1.2 mL/min; use 0.005-inch ID tubing for sample
flow rates >1.2 mL/min.
Requirement:
instrument, minimize the length of the tubing connecting the diverter
valve to the APCI probe. Doing so minimizes delays and dispersion.
