Agilent Multisampler G7167B

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

When: Injection volume reproducibility problems are observed. Leaks or blockages are observed. The limit for the rotor seal EMF counter is exceeded. The rotor seal needs to be replaced as part of the yearly maintenance.

CAUTION: Reduced life time of the injection valve. Component cleanliness is crucial for the life time of the injection valve. Replace the rotor seal in a clean environment.

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

Remove all capillaries from the injection valve with a 1/4 inch wrench.

NOTE: Remember the correct plumbing. Check the drawing on the side cover of the hydraulic box for correct plumbing.

Use a 9/64 inch hex driver to unscrew the two socket screws which hold the stator head in place.

CAUTION: Damage to the stator head. The polished sealing surface of the stator head contains six ports that access handling can easily damage. Avoid touching the polished surface of the stator head. Never place the polished surface on a hard surface.

WARNING: When opening capillary or tube fittings solvents may leak out. The handling of toxic and hazardous solvents and reagents can hold health risks. Please observe appropriate safety procedures (for example, goggles, safety gloves and protective clothing) as described in the material handling and safety data sheet supplied by the solvent vendor, especially when toxic or hazardous solvents are used.

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: 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.

Prerequisites: Finish any pending acquisition job. Return any plate on the workspace back to the hotel.

WARNING: Risk of injury by uncovered needle. An uncovered needle is a risk of harm to the operator. Do not open the safety lock of the needle assembly. Be careful working at the z-robot. Wear safety goggles, when removing the needle assembly.

In the Agilent Lab Advisor software, is the needle assembly in maintenance position?

Is the needle assembly still connected to the loop capillary?

Is the needle in the safety position?

CAUTION: Damage of the loop. The loop shape may be damaged if the loop is stretched or bent too far. Avoid to change the loop shape. Do not pull or bend the loop too far.

WARNING: Sharp needle. Uncovered needles may cause injuries. Make sure the needle is in the safety lock position.

Prerequisites: Finish any pending acquisition job and return any plate on the workspace back to the hotel.

CAUTION: Magnetic fields. Keep magnets at least 25 mm away from devices and objects that could be damaged by strong magnetic fields.

WARNING: Heart pacemakers. Bearers of heart pacemakers or implanted defibrillators must stay off at least 55 mm from the magnets.

Press the release buttons and pull the front door out.

For the Installation of the front door.

Insert the hinges into their guides.

Move the door in until the release buttons click into their final position.
