Advantages / Disadvantages of Fast GC
Advantages / Disadvantages of Fast GC
| Advantages of FAST GC - Shorter run times
- Greater sample throughput
- Cheaper columns
- Higher signal to noise ratio
- Lower bleed (thinner films)
| Disadvantages of FAST GC - Difficult to use for conventional GC/ MS
- Easy to overload the phase (less sample capacity)
- Careful attention required for splitless injections
- Conventional Van Deemter curves don’t apply (high pressure drop)
|
Methods for Faster Analysis - Shorter columns
- Higher Velocities
- Temperature Program Rates
- Pressure Programming
- Vacuum Outlet
|  | - Selectivity
- Narrow Bore Columns
- Carrier Gas Selection
- Turbulent Flow
