Abstract This gas-chromatographic method for assay of fluoxetine and norfluoxetine in human plasma involves extraction of the drugs and use of a 63Ni electron-capture detector. The linear range of detection is 25 to 800 micrograms/L for each drug. Overall precision (CV) in the concentration range of 10 to 100 micrograms/L for both drugs was approximately 10%. Accuracy (relative error) in the same concentration range was approximately +10%. None of the commonly prescribed antidepressants or tranquilizers that we tested interfere with the assay.

Work Up

Abstract Using an electron capture detector, a sensitive gas chromatographic method has been developed for the determination of the juvenile hormone methyl(2E, 6E)-10, 11-epoxy-3,7,11-trimethyl-2,6-dodecadienoate (JH III) in insect material. The sensitivity in electron capture detection of the bisheptafluorobutyrate was determined. The work-up procedure was checked by adding known amounts of JH III to insect material. The method seems equally applicable to all three juvenile hormones.
