Applicazioni
SPB®-5 Capillary GC Column was used for speciation of the nitrogen compounds (quantitatively), which are polar and somewhat basic in nature, with chemiluminescence detection. It may be used as stationary phase for determination of nivalenol and deoxynivalenol in cereals by electron-capture gas chromatography. It may also find application in being used as stationary phase in capillary column gas chromatography for determination of sterols.
