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 … WebbThe number of theoretical plates (N), is one index used to determine the performance and effectiveness of columns.They are an indirect measure of peak width for a peak at a specific retention time. The number of theoretical plates can be calculated: N=16 (t R /W) 2 , with t R = retention time and W= peak width.

Any chromatography column doesn't have any physical plate but it is a result of a … WebbSummary. Tray efficiency measures the performance of a distillation tray or trays against the maximum theoretical performance. Similarly, a concept called Height Equivalent to Theoretical Plate (HETP) is used to measure the performance in a packed column.
