4. Using tubing equal to 0.004-inch ID, connect port S of the selector valve
to the IonSABRE II 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).
5. Install the corona pin (see page 4-12 ).
Removing the IonSABRE II probe
Required material
Chemical-resistant, powder-free gloves
To remove the IonSABRE II probe:
1. Prepare the instrument for working on the source (see page 4-7 ).
2. Remove the corona pin (see page 4-12 ).
3. Disconnect the selector valve tubing from the IonSABRE II probe.
Warning:
To avoid electric shock, do not use stainless steel tubing
or stainless steel finger-tight screws to connect the selector valve
to the IonSABRE II probe; use the PEEK tubing and natural
(beige) colored PEEK finger-tight screws supplied with the
instrument.
Warning:
The LC system connections, IonSABRE II probe, and
source can be contaminated with biohazardous and/or toxic
materials. Always wear chemical-resistant, powder-free gloves
while performing this procedure.
Warning:
To avoid electric shock, ensure that the instrument is
prepared for working on the source before commencing this procedure.
