Abstract Phenothiazine, promethazine.HCl, chlorpromazine. HCl, promazine.HCl, and levomepromazine. HCl were chromatographed satisfactorily on a column containing 5% Apiezon L coated on Anakrom ABS, 100/110 mesh, using a hydrogen-flame ionization detector. This gas chromatographic technique is rapid and more specific than existing official methods. The use of an internal standard to improve precision will be investigated.

Abstract A rapid method has been developed in which gas-liquid chromatography is used to separate vanillin and ethyl vanillin in vanilla samples and determine them quantitatively. A flame ionization detector is used for the vanillin determination. 2-Phenoxyethanol is used as internal standard. The presence of any other substances is eliminated.

Abstract Free succinic acid can be determined in eggs by gas-liquid chromatography, using a flame ionization detector, after prior extraction of the acid from the sample by ether. Decomposed or incubator reject eggs all exhibited sample peaks with the same retention time as succinic acid, while undecomposed eggs showed no peaks.
