Abstract
The invention also relates to a method of packing an analytical column with packing particles. The method comprises the steps of pressurizing a first reservoir having packing particles disposed therein, with a solvent until the density of the solvent equals the density of the particles and forms a slurry where the particles are suspended in the solvent. Then, there is the step of fluidically connecting the first reservoir to an analytical column at essentially the same pressure as the first pressure such that the slurry flows into a chamber of the analytical column.
