What Does HETP Stand For?

HETP stands for Height Equivalent To A Theoretical Plate

HETP, or Height Equivalent To A Theoretical Plate, is a parameter used in chromatography to evaluate the efficiency of separation columns. It represents the height of a hypothetical column segment that would provide the same level of separation as one theoretical plate, essentially linking the performance of a column to its physical dimensions. A lower HETP value indicates a more efficient separation process, as it signifies that fewer theoretical plates are needed for a given separation. This metric is crucial for optimizing column design and improving analytical resolution in various chromatographic applications.
