Abstract

This invention describes an apparatus for the separation and collection of components in a sample of interest comprising: an ionization source; an ion mobility separator and an ion collector positioned to receive ions leaving the ion mobility separator. The ion mobility separator having an inlet to supply at least one separating substance which comprises particles which selectively interact with at least one analyte component of interest to certain degree different from the others. The analyte component of interest may be enantiomers, diastereomers, stereoisomers, isomers, etc. The ion collector can be used to conduct analytical, preparative, and semi-preparative separation. In addition, a combined primary electrospray and secondary electrospray ionization source is disclosed to enhance ionization efficiency of interest.
