Agilent Multisampler G7167-6005

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: The needle is visibly damaged. Leaks or blockages are observed. The limit for the needle interaction EMF counter is exceeded. The needle needs to be replaced as part of the yearly maintenance.

Prerequesites: Finish any pending acquisition job. Stop the flow at the pump and remove the solvent lines from the eluent bottles to avoid spilling solvent. Close the shutoff valves at the pump if available.

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.

WARNING: Toxic, flammable and hazardous solvents, samples and reagents The handling of solvents, samples and reagents can hold health and safety risks. When working with these substances observe appropriate safety procedures (for example by wearing goggles, safety gloves and protective clothing) as described in the material handling and safety data sheet supplied by the vendor, and follow good laboratory practice.

NOTE It is recommended to always exchange the needle assembly and the needle seat at the same time to prevent premature leakage.

In the Agilent Lab Advisor software select Service & Diagnostics > Maintenance Positions > Change Needle, Loop and Seat , click Start and wait until the needle assembly is in maintenance position. OR: In the Local Controller start the maintenance mode and select Change Needle, Loop and Seat function.

Lock the needle in the safety position.

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.

When poor injection volume reproducibility or when metering device / analytical head is leaking.

Start the maintenance mode and select Service Position in the Local Controller or in the Agilent Lab Advisor software

Disconnect all capillaries from the metering device

Release the bayonet lock, push and rotate the analytical head a quarter left. Then detach the analytical head assembly from the actuator

Push against the rear side of the metering device and rotate a quarter left to release the bayonet lock

Separate the analytical head and head body

Warning: Liquid dripping into the electronic compartment of your module can cause shock hazard and damage the module

Use a soft cloth slightly dampened with water or a solution of water and mild detergent for cleaning

Avoid using organic solvents for cleaning purposes

Do not use an excessively damp cloth during cleaning

Drain all solvent lines before opening any connections in the flow path

Is the surface of the module disinfected with a solution of 70% isopropanol and 30% water?

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.
