Figure 1–1: Evolution of particle size in liquid chromatography and the impact on
separation efficiency
It is apparent from the figure, above, that using 1.7-µm particles achieves higher efficiency that
persists as flow rate increases (lower HETP indicates higher efficiency). When operating in this
area of the plot, the peak capacity and the speed of a separation can set limits well beyond those
of conventional HPLC technology.
