Volumetric Method 1 (Recommended): Using a Syringe and Adapter
a. Locate the following items in the ICS-90 Ship Kit: luer fitting
(P/N 024305), luer coupler (P/N 042806), 1 mL syringe (P/N 016388),
and 10 mL syringe (P/N 016387). You will also need a stopwatch or a
clock or watch with a second hand (the computer’s clock can be used),
and a small beaker or other container for collecting waste.
b. Connect the luer coupler to the luer fitting.
c. Select the syringe to be used:
• For a 0.5 mL/min flow rate, use the 1 mL syringe
• For a flow rate above 0.5 mL/min, use the10 mL syringe
d. Disconnect the
ELUENT IN line from the ELUENT IN port on the
suppressor. Connect the luer coupler to the
ELUENT IN line, and connect
the syringe to the luer fitting (see Figure B-22
)
e. Using a stopwatch or clock’s second hand, time the flow of eluent into the
syringe for 60 seconds. Determine the volume collected by noting the
beginning and ending positions of the syringe plunger.
f. The volume of eluent collected in 60 seconds should be approximately
equal to the desired flow rate in milliliters per minute. For example, for a
flow rate of 1 mL/min, the volume should be 1.0
± 0.1 mL.
g. If necessary, adjust the flow rate knob, and then repeat the measurement.
Continue adjusting until the desired milliliters per minute is collected.
h. Reconnect the
ELUENT IN line to the suppressor.
