WhyDeactivate?
•
“Bare” FusedSilica tubing is reactive
–
Surface silanols are acidic
• Inertness to reactive compounds
–
Many compounds “See” the surface of the tubing
•
Batch-to-batchvariability
•
SomePolymers donotwet surface
–
Need tomatch surface tension of polymer and tubing
• Lowers bleed
• Improves efficiency
