Description
Column chromatograph, and a process for operation thereof 2 2 1 ',g)- 7 3
8
The present invention relates to a column chromatpgraph as defined in the preamble of the independent Patent Claim 1. It furthermore relates to a process for operation thereof.
The column chromatographs known at present and used for analytical and preparative capillary chromatography are, as those skilled in the art know, afflicted with numerous disadvantages, some of which are serious and the most important of which can be summarized briefly as foL.Lows.
As far as economic efficiency is concerned, it may be stated that the solvent consumption is relatively high and monitoring of the separation process by skilled personnel is rather expensive. In addition, the separation methods cannot be used directly by TLC or adapted for HPLC and MPLC. The apparatuses used are expensive, and the process is not e ffectiveLy reproducible in most cases. In addition, the recovery rate is usually considerably Less than 100% of all components.
The selectivity, of the known column chromatographs also Leaves something to be desired. Thus, it is not possible to produce specific column packings for aLL types of samples, from non-poLar RP phases through silica geL to polar normal phases, ion exchangers based on silica gel, wide-pore and chiral phases.
A further criticism, regarding safety, is that the known columns tend to run dry or overflow since operation cannot be carried out in a closed system using a saturated chamber. In addition, the known chromatography columns cannot be Left to run overnight since the capillary action is not retained in saturated chambers. Furthermore, the danger of explosion and fire due to readily volatile solvents must not be underestimated, and toxic emissions 35 are in many cases also released to the environment.
The Lack of versatility is a further disadvantage which is criticized time and time again in practice.
The object of the present invention is nate these disadvantages and ac cording.ly to propose a column chromatograph which has high flexibilityin practical use compared with conventional systems and, as far as the various abovementioned aspects are concerned, provides a considerable advance wit h respect to saving in time and c o S t S.
The column chromatograph accorjing to the invention is defined in the characterizing part of the. independent
