Second Step: Installation to Soft Connectors
Use this procedure for soft connectors, which are typically made from PEEK.
These are the following connections:
• to and from all bio-inert valves (injection valve in the autosampler and
• bio-inert ZDV unions (detector flow cells, multi-draw upgrade kit, capillary
• to the autosampler needle and
• to PEEK columns (like many bio-inert columns).
For the installation of bio-inert ZDV unions, refert to the Technical Note
"Installation of stainless steel cladded PEEK capillaries" (p/n G5611-90120).
