theoretical plate

[‚thē·ə′red·ə·kəl ′plāt]
(chemical engineering)
A distillation column plate or tray that produces perfect distillation (that is, produces the same difference in composition as that existing between a liquid mixture and the vapor in equilibrium with it); the packed-column equivalent of a theoretical plate is the HETP, or height (of packing) equivalent to a theoretical plate.

Column efficiency in the separation of biomolecules tends to be significantly lower than that found with small molecules, so there is always a drive to design columns that can maximize the number of theoretical plates without generating excessive back pressure or long run times," says Kerr.

Fast LC columns are packed with 3-[[micro]meter] particles, so they provide more theoretical plates (a measure of the number of partitioning steps a sample molecule undergoes as it passes through the column) than a comparable length of 5- or 10-[[micro]meter] particles.
