Notes:
Methanol, 2-Me-propanol-2, propanol-2, benzene, toluene and xylenes in gasoline blends were determined using a valveless multi-dimensional switching system (MDSS) with two packed columns and temperature programming.Compounds of interest, interfering with paraffins and naphthenes, were in a sequence of four heart cuts transferred onto the second column. The resulting baseline separation enabled precise quantitative measurement within a short analysis time. Instrument settings, times of switching and integration parameters were stored in an instrument memory file (user table) and thus high precision in the measurements was achieved.
