and Summary A gas liquid chromatography system for the analysis of complex mixtures of fatty and resin acids has been developed. On 30–40 m long, 0.3 mm ID glass capillary columns coated with 1,4‐butanediol succinate (BDS) and attaining over 90,000 effective theoretical plates, all main fatty and resin acids in wood extractives and various tall oil products can be separated and quantitatively determined without need of any prefractionation of the acids. Also the levopimaric acid is well separated. Retention values, including their temperature dependence, on columns coated with BDS or SE‐30 are given for 49 significant fatty and resin acids. Applications on wood extractives, sulfate soaps, and crude and distilled tall oil are presented and discussed.
