    摘要: A process for the purfication of synthetic oligonucleotides is described which drastically simplifies the hitherto very time consuming purification process. The deprotection solution is adsorbed without being concentrated on a carrier having reversed phase properties and optionally ion exchanger properties, the oligonuleotides without lipophilic protecting group are removed, their protecting group is cleaved off from the adsorbed oligonucleotides, the adsorbed oligonucleotides are washed and eluted from the carrier and then purified in a manner known per se.

    摘要: An apparatus for plasma treating workpieces in vacuum comprises a stack of plasma chambers (20). Handling of workpieces to and from the plasma chambers of the stack is performed in parellelism by one handling device and through lateral handling openings of the plasma chambers. The handling device is rotatable around an axis parallel to the handling openings of the plasma chambers and comprises transport means simultaneously movable radially with respect to the axis of rotation towards and from the handling openings.
