The IUPAC definition is: "Column chromatography is a physical method of separation in which the components to be separated are distributed between two phases, one of which is stationary while the other moves in a definite direction." Once you start running a column, don't let it 'run dry.' If the solvent level runs down below the

Separated columns in organic-filled (spirit) thermometers require a somewhat different technique in order to be reunited. The simplest and safest method is to force the liquid down the capillary by using a centrifuge, if one is available, with a cup deep enough to ensure that the centrifugal force is below the liquid column.

Therefore, normal-phase separation cannot be applied to LC-MS by simply switching to a normal-phase column or mobile phase. The key to determining whether normal-phase can be used for LC-MS is whether a mobile phase that allows ionization, such as methanol or acetone ( fundamental mobile phases ), can be added or not .
