Sample Inlet GC-MS

Sample Inlet

Purpose of the Sample Inlet

Before a sample can be analyzed by the Mass Spectrometer, it must reach the ion source and be ionized. The sample must be vaporized so molecules can be separated from each other.
This seemingly simple task is complicated by the billion-fold pressure differential between the source and the outside world. The sample introduction devices must therefore serve three
1) Place of entry
2) Transports the sample to the source
3) Preserves the vacuum within the Mass Spectrometer
