โœฆ Synopsis

Chromatographic techniques, namely column', thin-layer (TLC)2*3, gel permeation (GPC)"6, (GLC)3,8-'2 high-performance gel permeation (HPGPC)', gas-liquid and high-performance liquid chromatography (HPLC)'*, and TLC and HPLC coupled with flame ionization detection (FID) 12*13, have been reported for the determination of dimer acids'y"6*'2*'3 and their methyl esters2*3,7*8-'2. This paper describes improved GLC, HPGPC and TLC-FID methods for the determination of monomer, dimer and trimer contents in methyl esters of dimer acids.
