| Solvating gas chromatography (SGC) is a high-speed variant of supercritical fluid chromatography in which a large pressure drop is employed. Using laser-induced fluorescence, we have monitored the rate of elution of test compounds along the column and discovered that large losses in efficiency can occur toward the end of the column. This work led us to conclude that a temperature gradient along the column could improve efficiency and extend the range of compounds that can be separated by SGC. We will present results on the effect of various temperature gradients on the elution rate and efficiency for separations of a range of aromatic compounds. |
