General Guidelines

There are four main stages to refreshing the column by replacing the wetted flowpath. The first three stages are based

on the disassembly and reassembling each column sub assembly with new components before the final stage of

rebuilding and testing the complete column.

STAGE 1 – Refresh the Adjuster Assembly of the Evolve

STAGE 2 – Refresh the Tube Assembly of the Evolve

STAGE 3 – Refresh the Fixed Assembly of the Evolve

STAGE 4 – Rebuild and Test the Evolve

To disassemble and assemble the columns follow the instructions below. After reassembling the column ensure that the

column does not leak by performing a hydrostatic leakage test.

THESE PROCEDURES MUST BE PERFORMED USING AN OVERHEAD HOIST

NOTES: When assembling/dissembling attention should be paid to:-

Always use the correct size tools. A comprehensive tool kit was provided with the original column. See Table

below.

Ideally components should be at approximately room temperature. If not, take particular care as thermal

expansion or contraction may make components fit more tightly and thus more difficult to disassemble.

Dismantled assemblies should be rested on a clean, dry surface.

Pay particular care not to damage the edge of the flowcells.

When unpacking columns be careful not to scratch the inside of the column tubes.

Be careful not to damage stainless steel surfaces by bumping, knocking or scratching.

Do not over-tighten components and use correct torque settings as given in this guide.

Good engineering practices should always be followed and operations carried out in an approved and safe manner.

The components of the Evolve

handling aids should be utilised to safely lift or move the Column or its subassemblies. Provision is made for the use

of a hoist as eye bolts are fitted or supplied. It is essential that 'good practice' is adopted regarding the use of

appropriate slings and associated equipment. See original column manual for guidance.

All these operations should be performed by two people.
