How to separate overlapping peaks in hplc
WebGenerally, the most suitable range of K -values is expected to be between 0.5 and 2. A higher K -value might produce excessive broad peaks and an extended elution time; a lower K -value might lead to poor peak resolution. In addition, the separation factor between the adjacent components (α 1/2 = K1 / K2, K1 > K2) should be greater than 1.5 [ 9 ].
