theoretical plate

This increases the number of theoretical plates until separation can be attained.

A more detailed, expanded image of two trays can be seen in the theoretical plate article.

The required number of theoretical plates is 6 for the binary distillation depicted in Figure 1.

The theoretical plate in conventional distillation trays has no "height".

Those steps represent the theoretical plates (or equilibrium stages).

Efficiency factor is synonymous with plate number, and the 'number of theoretical plates'.

Capillary electrophoresis separations can have several hundred thousand theoretical plates.

Conversely, for a given desired separation, the more reflux is provided, the fewer theoretical plates are required.

However, the theoretical plate in packed beds, chromatography and other applications is defined as having a height.

More theoretical plates lead to better separations.

The number of theoretical plates, or separation efficiency, in capillary electrophoresis is given by:

The eluent from one column is transferred to another; the more columns that are used, the more theoretical plates can be achieved.

Each vaporization-condensation cycle (called a theoretical plate) will yield a purer solution of the more volatile component.

Corrections can also be made to take into account the incomplete efficiency of each tray in a distillation column when compared to a theoretical plate.

The concept of theoretical plates in designing distillation processes has been discussed in many reference texts.

The theoretical plate concept was also adapted for chromatographic processes by Martin and Synge.

This is particularly true in gas-liquid chromatography where column lengths up to 60 m are possible, providing a very large number of theoretical plates.

The height equivalent of a theoretical plate (HETP) will be greater than expected.

The concept of theoretical plates and trays or equilibrium stages is used in the design of many different types of separation.

In isocratic elution, peak width increases with retention time linearly according to the equation for N, the number of theoretical plates.

With a relative volatility of 4, the required number of theoretical plates decreased to 9 with a reflux ratio of 0.66.

The more reflux provided for a given number of theoretical plates, the better is the column's separation of lower boiling materials from higher boiling materials.

In other words, having more theoretical plates increases the efficacy of the separation process be it either a distillation, absorption, chromatographic, adsorption or similar process.

Since an actual, physical plate is rarely a 100% efficient equilibrium stage, the number of actual plates is more than the required theoretical plates.

Such a column can be calibrated by the distillation of a known mixture system to quantify the column in terms of number of theoretical plates.
