Method to level columns

Abstract:

When levelling chromatography columns a spirit-level is normally used. Especially for large columns this method may be difficult and non-exact. To use a small amount of liquid inside the column as an internal spirit-level is the idea.

Detailed description:

When levelling columns, for example chromatogrpahy columns, spirit-levels are usually used. Especially for large columns this way of levelling may be difficult and not as exact as required. The problem is that the spirit-levels normally are too small and that it is hard to find a suitable position for the spirit-level. The idea here is to use the column itself as a sprit-level. A small amount of liquid, for examle water, is provided to the empty column. The amount of liquid should preferably be so small that it does not cover the whole bottom of the column. Suitably 25-40% of the bottom surface is covered by this small amount of liquid. The levelling of the column is thereafter adjusted by suitable means provided for that, for example a hydraulic jack can be used to adjust the height on the oclumns stand foot. The column is correclty levelled when it can be seen that the liquid on the bottom of the colum centers around the center point of the column bottom. Markings could be provided around the center point of the column bottom in order to facilitate this.

Another possibility would be to use more liquid for the levelling process, for example to fill up the column with a few ce...
