PLOT Layer is often deposited as non
homogeneous film
FLOW Restriction
Ideal “open Path: Flow-restriction factor = 1.0
PLOT column with Flow-Restrictions: Flow restriction factor “F” = 0.2-0.8
This was one of the reasons why we could replace
Varian and Agilent PLOT columns for:
• Siemens
• Agilent micro GC
• C2V (Thermo)
• Schlumberger
• Many companies that supply Analyzer solutions
(PAC, Interscience,..)
Transportation
Transportation of PLOT columns
During transport columns are subjected to
uncontrolled:
• Vibrations
• Pressure changes
• Temperature changes
• Shocks
Which all can destabilize the adsorption layer..
