Agilent Multisampler G7137A

Warning: For bio-inert modules use bio-inert parts only!

When: The flush head is leaking.

Prerequesites: Cleaning tissue, Appropriate solvent like isopropanol or methanol

In the Local Controller start the maintenance mode and select Service Position.

In the Agilent Lab Advisor software select Service & Diagnostics in the system screen (Tools) > Maintenance Positions > Change Metering Device , click start and wait until the metering device is in maintenance position.

Remove capillaries and valves from the flush head.

Press and turn the Flush Head a quarter left (bayonet fitting) and detach the metering device from the actuator.

Pull the flush head away from the hydraulic box

For bio-inert modules use bio-inert parts only! For biocompatible modules use bio / biocompatible parts only! Do not mix with bio-inert parts.

Prerequesites: Switch off the power of the Multisampler

NOTE: Please bear in mind that depending on which valve you have installed the images may slightly differ from the actual item.

Turn the spanner nut counter clockwise until the injection valve head detaches from the hydraulic box (Do not use wrenches on the spanner nut).

Remove the spanner nut from the injection valve head.

Take the replacement injection valve head and insert it into the open actuator slot of the hydraulic box. Rotate until the unions at the base of the replacement injection valve head and the valve actuator engage.

If the outside pin does not fit into the outside groove, you have to turn the valve head until you feel that the two pins snap into the grooves. Now you should feel additional resistance from the valve drive while continue turning the valve head until the pin fits into the groove.

NOTE Check the orientation of the rear side. Verify the correct position of the Valve TAG.

Warning: This procedure requires technical knowledge and should be performed by trained personnel only.

WARNING: When opening capillary or tube fittings solvents may leak out. The handling of toxic and hazardous solvents and reagents can hold health risks.

NOTE: The peristaltic pump cartridge is a replaceable unit. The tubing inside the pump is not replaceable.

Press the two clips on the front of the peristaltic pump cartridge.

Pull the cartridge forward off the motor shaft.

Disconnect the tubing coupler leading to the wash port and the tubing coupler coming from the solvent bottle.

Push the new cartridge onto the motor shaft until the clips click into place.

Connect the wash port tubing to the upper tubing of the new cartridge (use sand paper to get a good grip on the tubing).

Connect the inlet filter of the solvent bottle again. Use the syringe to draw enough solvent for completely filling of the peristaltic pump tubing before continuing to prime the peristaltic pump.

WARNING: Flammable refrigerant. Formation of flammable gas-air mixtures inside the Sample Thermostat and laboratory.

WARNING: Flammable refrigerant used. When handling, installing and operating the Sample Thermostat, care should be taken to avoid damage to the refrigerant tubing or any part of the Sample Thermostat.

WARNING: In the event of a damage. Keep open fire or sources of ignition away from the device. Ventilate the room for several minutes. Do not use the Sample Thermostat any more.

WARNING: Heavy weight. The module is heavy. Carry the module at least with 2 people. Avoid back strain or injury by following all precautions for lifting heavy objects.

CAUTION: Routing of the condensation tubing. Proper routing of the condensation tubing is critical for correct condensate drainage.

CAUTION: Condensate inside the module. Damage to the electronics of the module. After installation of the Sample Thermostat, wait at least 30 min before switching on the module.

Ensure that the on/off switch on the front of the module is OFF (switch stands out).

Disconnect the power cable from the sampler.

Ensure that no condensate remains inside the thermostat before proceeding forward.
