I have some columns for my Thermo Scientific GC-MS:
1) DB-WAX
2) DB-1
c) DB-17HT
d) VF-1MS
e) TR-FAME
f) TG-5MS
g) TG-WAXMS A
In my opinion, for polyphenols as flavonoid (and their glicosides) and phenolic acids (present in vegetable, grains, food analysis), I would prefere DB-1, VF-1MS and TG-5MS.
Your opinion will be valuable for me...a lot!
I am using TG-5MS. but I expected better results than the ones I am having...
