IMPORTANT
Before pressurizing the eluent bottle, connect the liquid line from the pump to the eluent bottle and fill the eluent bottle.
WARNING
Risk of bottle rupture or leakage: If pressurized bottles are required, use only 2-liter bottles (P/N 046548) with caps.
CAUTION
Never pressurize eluent bottles above 69 kPa (10 psi). Pressurizing an eluent bottle above this limit can cause the eluent bottle to leak or burst.
Never pressurize eluent bottles directly from a gas source. Pressurize bottles only when using the Dionex digital pressure regulator (PN 22185-62706); otherwise, the eluent bottle may leak or burst.
Avoid connecting the inert gas supply line to two or more instruments unless a suitable regulator supplies the Dionex Inuvion IC System at 100 psi (690 kPa) or less.
Procedure
- Turn the gas regulator knob fully counterclockwise. This ensures that there is no pressure to the eluent bottle when the gas source is turned on.
IMPORTANT
When pressurizing the eluent bottle(s), if the regulator knob is inadvertently adjusted so that the bottle pressure exceeds 124 to 152 kPa (18 to 22 psi), you may hear gas hissing from the instrument (this is normal). To avoid wasting gas, correct the outlet pressure to between 34 and 41 kPa (5 and 6 psi) as soon as possible.
- Close the gas shutoff valve on the eluent bottle cap.
- Turn on and adjust the gas source to between 172 and 345 kPa (25 and 50 psi). DO NOT exceed an input pressure of 690 kPa (100 psi), as this may damage the digital pressure regulator or eluent bottle(s).
- Pull out the gas regulator knob, turn it clockwise, and adjust the pressure to between 34 and 41 kPa (5 and 6 psi). Push back the regulator knob to lock. You can monitor the pressure from the digital display in the upper-left corner of the component panel.
- If the liquid line from the pump is connected, you may slowly open the gas shutoff valve on the eluent bottle cap.
