TWO DIMENSIONAL HPLC (2-D HPLC)
Two dimensional HPLC or 2-D HPLC facilitates the separation of complex mixtures by using different chromatography modes as sequential steps.  This means that the output from the first HPLC column is automatically or manually transferred to the next HPLC column in order to observe and quantitate many more components of the analyte mixture.
