Agilent 160-7625-5 is deactivated fused silica tubing designed for GC and GC/MS applications. It has a 0.15 mm inner diameter and a length of 5 m. The deactivated inner surface minimizes unwanted analyte interactions and supports use as an inert flow path, retention gap, guard column, or transfer line.
Deactivated Surface
The deactivated inner surface minimizes active sites on the fused silica and helps reduce analyte adsorption.
This can be beneficial for:
- polar compounds,
- active analytes,
- trace-level measurements,
- compounds sensitive to surface interactions.
Retention Gap Applications
When used as a retention gap, the tubing is installed ahead of the analytical column.
It can help:
- improve analyte focusing,
- reduce solvent effects,
- improve peak shape,
- protect the front section of the analytical column.
Guard Column Applications
The tubing can also be used as a guard column to protect the analytical GC column from:
- nonvolatile matrix components,
- contaminants,
- deposits.
Transfer Line Applications
The deactivated surface also makes the tubing suitable as an inert transfer line in GC and GC/MS configurations where surface interactions should be minimized.
