If you have a hot sauce extract containing nordihydrocapsaicin, capsaicin, dihydrocapsaicin, and homodihydrocapsaicin, the Cogent Bidentate C18 2.o™ HPLC column is a good choice for sufficient separation when the compounds are analyzed by LC-MS; look for the [M+H]+ ions.
The following gradient should be a good starting point:
You may get EICs which look like this:
