-
The mass balance model of daul retention mechanism in RP-HPLC is established based on the theory of mass transfer. The first moment and the second, third central moments are derived. The total capacity factor k' and HETP in daul retentio-mechanism can be expressed as:
k′=k′_1+k′_2
H=(2γD_m)/μ+2λa_o+{k[k_0+(1+k_0)(k'_1+k'_2)]~2d~(5/3)_pu~(2/3)}/{(1+k_0)~2(1+k'_1+k'_2)~2D~(2/3)_m}
+{θ[k_0+(1+k_0)(k'_1+k'_2)]~2d_pu}{30D_mk_0(1+k_0)~2(1+k'_1+k'_2)~2}+(2u)/{((1+k_0)(1+k'_1+k'_2)~2}(k'_1/k_(d1)+k'_2/k_(d2))
The effects of chromatographic parameters on column efficiency and peak shape are discussed. The approaches to increase column efficiency and eliminate the tail of chromatogram are explained. -
