I am very new to GC-MS and so please forgive my ignorance. I want to observe compounds that are eluting with the solvent (I am using DCM). I tried using a fairly low temperature (40°C) to start (holding for five minutes before slow (10°C/min) ramp, but since that isn't working I thought I'd try another solvent- maybe ethyl acetate but I need to introduce a second solvent delay or something so that I can see the low boiling compounds and then turn off the detector while the solvent is eluting. I know this can be done, but I don't know how. Can anyone help?
I don't have a head-space contraption- just auto-liquid injector.
Our Instrument is an Agilent 5975-6850 with an HP-5 column.
Also wondering if you have a recommendation for training resources (aside from online)
