SYSTEM AND METHOD FOR THE PREPARATION OF ARRAYS OF BIOLOGICAL OR OTHER MOLECULES

摘要

A method and system of separating species in a mixture by conversion to gas phase ions, separation based on mass/charge ratio and/or mobility, and collection of the separated ions. The system (18) includes a multiplexed electrospray ion source (19) for producing streams of ionized species (23), which are fed to a linear ion trap (24) for separation. The separated species pass through a focusing lens (29) for deposition on a spot (14) on substrate.
