The reason I am looking for this is that the system will be used by an organization whose staff has minimal background in GC-MS spectroscopy, and are not trained in sample preparation techniques of samples for GC.
On the plus side, they have a prep HPLC system with means that the samples whose mass spectrum they want to obtain are already purified (so no need for GC separation).
Since most of you here are much more knowledgeable about these things than me, I'm hoping that one of you knows of a EI-MS system where (a pure) sample can be introduced directly into the mass spec to obtain a EI mass spectrum.
I'm also guessing that such a system would nonetheless require some front end to bring the analytes into the gas phase.
I know similar systems are made by Waters, but the problem is that they us ESI as their ionization source, which would not work for obtaining EI-Mass spectra that can be compared to NIST libraries and used to build EI-MS spectral libraries.
If you know of any such system I would love to hear from you!
If you know that this type of system doesn't exist, I'd also love to hear your thoughts as to why this may not be feasible in practice.
Thank you!
