Prediction of gas chromatographic peak width in capillary columns at different temperatures, carrier gas flows, column lengths, inside diameters and carbon numbers Width factor (w f ), relative band broadening (b r ) and retention factor are linearly correlated as ln w f = lnb r + lnk [Chromatograp
The elution temperatures and degree of separation of a model system series of hydrocarbons were followed as functions of the rate of temperature programming and carrier gas velocity. Graphs are presented that permit individual assessment of these variables. Lower elution temperatures can be achieved
## Abstract The effect of dilution of the chiral stationary phase octakis (3βOβbutyrylβ2, 6βdiβOβpentyl)βΞ³βcyclodextrin in the achiral polysiloxane OVβ1701 on the separation factor was investigated over a wide concentration range. The loss in enantioselectivity was only negligible down to a dilutio
