Cleaning the Valve
Body
Thermo Scientific
Follow these instructions to clean the valve body.
1. Wet a cotton swab with a solvent compatible with the chromatographic
system. Isopropyl alcohol is recommended.
2. Gently swab the polished interior of the valve to remove any loose
residue.
3. Blow with clean compressed gas to remove any lint left by the swab.
4. Visually inspect the interior of the valve body. The conical surface
should appear highly polished. If any scratches are visible between the
ports or anywhere that might suggest a potential leakage path or wear
source, the valve should be returned to the factory for grinding and
polishing.
