The ability of a gas chromatographic (GC) column to separate two compounds is determined by its analytical resolution. The height equivalent to a theoretical plate (HETP) is given by Eq. 1. For a rectangular column, the average linear velocity u is given by Eq. 2. The evel of approximation can be varied.
