1. What sample introduction techniques are available for GC/MS analysis?
Here we briefly describe the eight main techniques for GC/MS sample pretreatment and introduction.
Samples are pipetted directly into the GC injection port using a needle. Analytes are usually derivatized to lower their boiling point, allowing the sample to be injected at a lower temperature.
Samples are pre-heated within the autosampler.
