Figure 7.8 Unified Chromatography is achieved by realizing that the apparent barriers
between the previously mentioned techniques are only arbitrary naming conventions, and that
no real discontinuities exist between the techniques as long as the two-phase region is
avoided. Reproduced by permission of the American Chemical Society.
be modified for handling (in addition to ordinary liquids) very volatile fluids such as
CO 2 , propane, and 1,1,1,2-tetrafluoroethane. Column temperature control must be
added if not already provided. Finally, a device for controlling the mobile-phase
pressure at the column or detector outlet is necessary.
