Summary 1. A continuous liquid‐liquid extractor was designed and procedures were devised for the determination of total fatty acids, oxidized acids, and unsaponifiable matter. These procedures give results that are in agreement with the present A.O.C.S. Methods. 2. The continuous liquid‐liquid extractor has the following advantages:It is simple in design, easy to operate and keep clean. The inner tube which gives better solvent dispersion than standard commercial pieces can be made out of ordinary glass tubing at relatively low cost. The operation is automatic. Once a bank of these extractors is set up, the operator is free to do other work. The extractions are made rapidly without troublesome emulsions. Greater accuracy is possible because of limited handling. The enclosed system minimizes health and fire hazards inherent in the present A.O.C.S. Methods.
