摘要:

Supercritical fluid chromatography (SFC) techniques have been developing rapidly, now much attention has been paid to the research for its thermodynamic basis. Based on thermodynamic theory, we have derived the straight linear relationship between the logarithm of capacity factor and carbon number for homologues in SFC. There is a common intersection point among the ln k' vs. n straight lines of homologues at different temperatures. We can determine the intersection point equation of homologues in SFC.
