I want to know the decomposition products that can occur from the sample input to the injector until it reaches the mass detector. GC/MS analysis are performed with a Shimadzu model GCMS-QP 2010 Ultra gas chromatograph, equipped with a Rtx-5MS Crossbond 5% diphenyl 95% dimethyl polysiloxane capillary GC column(30 m length, 0.25 mm I.D., 0.25 μm film thickness.
Hallo Javier
The alkaloids like bufotenine similar to serotonin are simple to measure in GCMS, there should be no degradation in the injector or ec..
If you use EI have a look to the NIST spectra database:
http://webbook.nist.gov/cgi/cbook.cgi?ID=C487934&Mask=200 (without derivatisation).
Bufotenin (5-hydroxy-N,N-dimethyltryptamine) has b.p. 320 deg C. It does not decompose at least up to this temperature.
