Abstract
The invention relates to a process for the production of chromatography columns or capillaries containing sorbents of monolithic mouldings which can remain directly in their gelation mould after production. This is achieved by the process according to the invention, in which the gelation mould is repeatedly filled with the monomer sol.
Claims6
Process for the production of monolithic porous mouldings which completely fill their gelation mould, characterised by the following process steps:
- a) provision of a gelation mould;
- b) filling of the gelation mould with monomer sol;
- c) polymerisation of the monomer solution;
- d) ageing of the gel formed in step c) to form pores;
- e) filling of the dead space formed in step d), with further monomer sol, and repetition of steps c) to d),
- where step e) can be carried out one or more times.
