FREQUENCY MODULATED CORRELATION CHROMATOGRAPHY

Cross correlation chromatography experiments up tilI now have assumed a linear system. However, the use of multiple injections needed for these types of experiments often drives the system into nonllnearlty. By frequency modulating a signal, the change in the amount of solute on the column at any time can be restricted to a small range. Thus each injection experiences a nearly identical environment. This enables one to work In nonlinear areas of an isotherm and still take advantage of signal processing techniques, such as correlation and deconvolution. © 1979, American Chemical Society.
