Wallace J, Shimek Jr E, Harris S, Stavchansky S
Clin Chem . 1981 Feb; 27(2):253-5. PMID: 7460275
We describe a procedure for the liquid-chromatographic determination of promethazine in low-nanogram concentrations in serum. Triflupromazine is used as the internal standard. The method is based on a single extraction...

Wallace J, Shimek Jr E, Harris S
J Anal Toxicol . 1981 Jan; 5(1):20-3. PMID: 7218774
A method is described for the determination of amitriptyline, nortriptyline, imipramine and desipramine at low nanogram concentrations in serum. Separation and quantitation are performed by reversed-phase, isocratic, high-performance liquid chromatography...

Wallace J, Harris S, Shimek Jr E
Clin Chem . 1980 Dec; 26(13):1905-7. PMID: 6777085
We evaluated a commercially available enzyme immunoassay method for determining the concentration of total diazepam plus its active metabolite, nordiazepam, in small amounts of serum and urine. The coefficients of...

Wallace J, Schwertner H, Shimek Jr E
Clin Chem . 1979 Jul; 25(7):1296-300. PMID: 378460
We describe the use of electron-capture gas chromatography or reversed-phase "high-performance" liquid chromatography for concurrent analysis for diazepam and nordiazepam in serum. In the gas-chromatographic analysis our use of a...

Wallace J, Schwertner H, HAMILTON H, Shimek Jr E
Clin Chem . 1979 Feb; 25(2):252-5. PMID: 581562
We describe the determination of ethosuximide and desmethylmethsuximide, simultaneously or separately, in 50 to 100 microliter of plasma or serum. Derivatives of ethosuximide and desmethylmethsuximide formed by reaction with pentafluorobenzoyl...
