<p>This invention describes an apparatus for the separation and collection o f components in a sample of interest comprising: an ionization source; an io n mobility separator and an ion collector positioned to receive ions leaving the ion mobility separator. The ion mobility separator having an inlet to s upply at least one separating substance which comprises particles which sele ctively interact with at least one analyte component of interest to certain degree different from the others. The analyte component of interest may be e nantiomers, diastereomers, stereoisomers, isomers, etc. The ion collector ca n be used to conduct analytical, preparative, and semi-preparative separatio n. In addition, a combined primary electrospray and secondary electrospray i onization source is disclosed to enhance ionization efficiency of interest.< /SDOAB></p> |
