2009年9月2日 · Column efficiency, also known as plate count, is a measure of the dispersion of a peak. Narrow peaks take up less space in the chromatogram and thus allow more peaks to be separated. They are also easier to integrate since they give better resolution and less overlapping. Efficiency is usually explained using the concept of theoretical plates.
2021年12月10日 · Firstly, HPLC can be performed at room temperature. In contrast, GC requires a much higher temperature of 150°C to ensure samples are volatile. Because of this volatility, however, GC is much quicker than HPLC. Volatile compounds can move through the system in minutes or even seconds, compared to HPLC runs are generally between 10-60 minutes.
Void volume In nearly all modes of HPLC, some form of selective retention by the stationary phase is required for column resolution. In order to know whether a compound is retained, one must calculate the column void volume, V 0, by measuring the retention time for an unretained solute at a given flow rate.
