Operating Manual

The Dionex Inuvion IC System does not require pressurized bottles. However, if the eluent is manually degassed or is sensitive to contamination, Thermo Fisher Scientific recommends pressurizing the bottle with helium or nitrogen.

An eluent monitor module can be added to the instrument configuration to continuously monitor the eluent volume and alert you when the level is below the user-specified threshold. Each eluent monitor can support one bottle. You can monitor up to three bottles, using the appropriate kit(s):

Liquid Level Sensing Kit for 2-liter bottles (P/N 22815-62707)
Liquid Level Sensing Kit for 4-liter bottles (P/N 22815-62708)

For more information, see Install the eluent monitor.

The digital pressure regulator (PN 22185-62706) required for pressurizing eluent bottle(s) must be ordered separately. Do not directly pressurize an eluent bottle from a gas source.

WARNING

Risk of bottle rupture or leakage: If pressurized bottles are required, use the Thermo Scientific Digital Pressure Regulator (P/N 22185-62706).

WARNING

Risk of bottle rupture or leakage: Do not pressurize eluent bottles above 10 psi (69 kPa).

Task	Procedure
Filter the deionized water	Filtering removes small particulates in deionized water that may contaminate the pump check valves and cause erratic flow rates or loss of prime. Filtration is advised, but not required, when using a Dionex Inuvion IC RFIC System. Procedure Locate the end-line filter (P/N 045987) provided in the Dionex Inuvion IC System Ship Kit (PN 22185-62000). Install the end-line filter at the end of the deionized water line, inside the bottle. For Dionex Inuvion IC Systems using manually prepared eluent (not RFIC), verify that the end of the filter extends to the bottom of the bottle and that the filter is submerged in deionized water. This prevents air from entering into the lines.
Fill the eluent bottle	Fill the bottle with ASTM filtered, Type I (18.2 megohm-cm) deionized water that meets the specifications in Deionized water requirements for IC.
Connect the eluent bottle	If it is not already connected, connect the ELUENT BOTTLE OUT line from the bottle cap to the ELUENT IN line, which extends from the tubing chase on the top cover of the Dionex Inuvion IC System.

Procedure

Filter the deionized water

Filtering removes small particulates in deionized water that may contaminate the pump check valves and cause erratic flow rates or loss of prime. Filtration is advised, but not required, when using a Dionex Inuvion IC RFIC System.

Procedure

Locate the end-line filter (P/N 045987) provided in the Dionex Inuvion IC System Ship Kit (PN 22185-62000).
Install the end-line filter at the end of the deionized water line, inside the bottle.
For Dionex Inuvion IC Systems using manually prepared eluent (not RFIC), verify that the end of the filter extends to the bottom of the bottle and that the filter is submerged in deionized water. This prevents air from entering into the lines.

Fill the eluent bottle

Fill the bottle with ASTM filtered, Type I (18.2 megohm-cm) deionized water that meets the specifications in Deionized water requirements for IC.

Connect the eluent bottle

If it is not already connected, connect the ELUENT BOTTLE OUT line from the bottle cap to the ELUENT IN line, which extends from the tubing chase on the top cover of the Dionex Inuvion IC System.
