Apparatus and methods for analysis and sorting of particles such as polymer beads

Abstract From the Canadian patent

The present invention relates to an apparatus for analysing beads and particles, such as polymer beads used e.g. for solid phase synthesis. The apparatus in one embodiment comprises a rotatable circular disc comprising a , plurality of through-going inlets, wherein an individual bead from a composition comprising different beads can be fixed to the disc at the endposition of a through-going inlet by applying a pressure drop over said disc comprising said through-going inlets. The pressure drop results in beads being sucked (i.e detachably fixed) onto the disc on top of the through-going inlets. When the disc is rotated the beads are transferred from the position where they initially …
