WebDec 7, 2012 · The HLB value also depends on the chain length(s) of the fatty acids attached to the emulsifier; short fatty acid chains lead to higher HLB values [6,7]. The particle diameters and PDI values of the nanodispersions prepared with the different emulsifiers at constant concentrations are shown in Table 2 . WebIn reversed-phase HPLC, fatty acids are separated both by chain length and by degree of unsaturation. The first double bond reduces the effective chain length by a little less than 2 carbon units, so an 18:1 fatty acid elutes just after 16:0. A second and further double bonds have smaller effects on retention so an 18:3 fatty acid elutes just ...
