In the ideal solvent system the compounds of interest are soluble to different degrees. This particular solvent system is very useful for separation of peptides and other highly polar compounds despite low Sf (see Table 2 ), but the conventional multilayer coil in the type-J coil planet centrifuge also has low retention of the stationary phase. t-Butanol-acetic acid-water (3:1:1, v=v)a. n-Butanol-acetic acid-water (4:1:5, v=v)a. water-methanol- ethylmethylketone- acetylacetone (13:3 .
