Rapid, sensitive gas-liquid chromatographic method for determination of amitriptyline and nortriptyline in plasma using a nitrogen-sensitive detector

Determination of benzidine, dichlorobenzidine, and diphenylhydrazine in aqueous media by high performance liquid chromatography

“…°Zero recovery was realized for the samples spiked with 2 ppm NaOCl and therefore this data is not reported in the table. Five-milliliter volumes of distilled water at the stated pH were stored at either room temperature or 4 "C, in the dark, for seven days. The solutions were then extracted and assayed by HPLC.…”
