Abstract
A method and system of screening or selecting a mobile phase eluent for a chromatography column is provided. A sample for chromatographic analysis or purification is combined with a solvent and passed through a membrane. A pressure measurement is taken of the sample/solvent combination in the system prior to the membrane. The pressure measurement may be compared to a second pressure and an appropriate solvent may be selected based on the relationship between the first measured pressure and the second pressure.
