- Mass Spectrometry
- Advantages
- small sample size
- Fast
- differentiates isotopes
- small sample size
- Disadvantages
- doesn't directly give
structural information
(although we can often
figure it out)
- Needs pure compounds
- Difficult with non-volatile compounds
- doesn't directly give
structural information
(although we can often
figure it out)
- Advantages
- Gass Chromatography
- Disadvantages
- Difficult to use for conventional GC/
- Easy to overload the phase
(less sample capacity)
- Careful attention required for splitless injections
- Difficult to use for conventional GC/
- Advantages
- Shorter run times
- Greater sample throughput
- Cheaper columns
- Shorter run times
- Disadvantages
