WebbThe theoretical plate in conventional distillation trays has no "height". It is simply a hypothetical equilibrium stage. However, the theoretical plate in packed beds, chromatography and other applications is defined as having a height. Distillation and absorption packed beds Webbfeatures. Theoretical plate numbers are indirect measure of peak width for a peak at a specific retention time. Columns with high plate numbers are considered to be more …

Theoretical Plates

WebbThe plate number depends on the length of the column. The extreme value of 10 6 plates was obtained with an open tubular gas chromatographic column 1.6 kilometres (1 mile) long. A more appropriate parameter for measuring efficiency is the height equivalent to a theoretical plate (or plate height), HETP (or h ), which is L / N , L being the length of the … WebbChromatography is defined as a procedure by which solutes are separated by a dynamic differential migration process in a system consisting of two or more phases, one of which moves continuously in a given direction and in which the individual substances exhibit different mobilities by reason of differences in adsorption, partition, solubility, … WebbTheoretical plate number (N) is an index that indicates column efficiency. It describes the number of plates as defined according to plate theory, and can be used to determine column efficiency based on calculation in … rcht mca form
