摘要:
The present invention relates to a process for the production of the largest possible spherical, monodisperse polyvinylpyrrolidone (PVP) seed particles in the micron range by dispersion polymerisation. The particles obtained in this way represent novel starting materials for the production of macroporous polymer particles, which can in turn be employed in preparative and analytical chromatography for protein preparation. They can also be employed as base material for further reactions.The novel process for the polymerisation of N-vinylpyrrolidone, which is inexpensive to carry out, gives particles having optimised quantities, such as monodispersity, sphericity and particle diameter, which can be employed in further reactions and have advantageous, in particular improved, properties for use in chromatographic separation methods.

The invention relates to a process for the preparation of a separating material having improved binding capacity, and to materials prepared and to the use thereof for the separation of charged or uncharged biopolymers from liquids.
摘要:
A microcomponent connection system (1) having an accomodation device for plate-shaped microcomponents (7) has a connection block (2) and a lifting device (6), by means of which the microcomponent (7) and the connection block (2) can be pressed against one another. The connection block (2) has electrical and fluid line connections (8, 9) and optical line connections (16), each of which projects in a sprung or spring-mounted manner on the underside of the connection block (2). In order to connect the microcomponent (7) to the associated line connections (8, 9, 16), the microcomponent (7) is pressed by the lifting device (6) in the direction of the connection block (2) against the electrical line connections (8) or fluid line connections (9) designed as electrically conducting spring tongues or as hollow rams (10), or optical line connections (16).
