Larger HETP values indicate better efficiency of chromatographic separation

Question:

Larger HETP values indicate better efficiency of chromatographic separation

true or false

Answer

false

This is false because efficiency is optimized when N is maximized and HETP is minimized and the lower the HETP, the better the resolution and the more efficient the separation

Explanation

The height equivalent to a theoretical plate (HETP) can be calculated when both N and the column length (L) are known

Knowing that HETP =  LN

then we can conclude that the lower the HETP, the better the resolution and the more efficient the separation an thus not true to have a larger HETP values and conclude that there is efficiency
