Capillary GC on‐column injection of polychlorinated dibenzo‐p‐dioxins: Elimination of peak splitting and distortion through injector temperature control

Determination of polar organic solutes in methanol using hot on-column injection capillary gas chromatography

“…When the hot on-column technique is utilized, large injection volumes of nonpolar solvents can be tolerated (up to 10 pL); however, injection volumes of polar solvents, especially methanol, are limited to less than 1 KL (9)(10)(11). The retention gap technique ( 4 1 2 ) and techniques using independent temperature programmable on-column injectors (13)(14)(15) have also overcome the problem of peak splitting or distortion. These techniques, however, do not specifically address injection of polar solutes in methanolic solutions.…”
