Yes, I've seen from your posts how invested you are in this issue. Stay classy, my friend.
In examining the tracings closely, it appears that the current Shulton has 4 strong spikes (at 10.4, 11.3, 13.2, 13.7) that are either absent or much weaker in the vintage. The spike at 14.0 is much stronger in the vintage than in the current Shulton. The spikes at 14.1 are strong in both, but much stronger in the current. In addition there are other minor variations. The current and vintage do not appear to be the same formulation, and the observed differences could account for differences in odor. Such differences would also depend on the potency of those components, the identity of which are not known. This is not my area of expertise, but I'd like to know why do you feel that the formulations are identical. It might be worth doing a gas chromatography/mass spectrometry to actually identify those components that differ between the two, as they might be quite important parts of the overall aromas. Thank you for a very interesting contribution!Based on overall similarity, it is concluded that currently produced Shulton Old Spice (a product of India) and vintage Shulton Old Spice are essentially identical.
Yeah, SPME could be interesting. Still need that dang quadrupole, though.You would not need to use HS for the GC-MS, you could try a SPME injection. I think that would get the job done in a normal inlet. This thread has made my day. It is not often I get to see GC work outside of my job. I have been working with GCs in one form or another since '93. Thanks for the interesting post.
What no spares lying around?Yeah, SPME could be interesting. Still need that dang quadrupole, though.
