Detection limits of methamphetamine (MA) and amphetamine (AP) in urine by HSGC/CI-MS were found to be about 10ng/ml (/>10) by monitoring quasimolecular ions of these compounds; /150 and 136 observed on their mass spectra, respectively. Furthermore, the most sensitive CI-MS method was ...
Methamphetamine(MET) Panel Test is used for in vitro quantitative detection of Methamphetamine content in human urine. Methamphetamine is an addictive stimulant drug that strongly activates certain systems in the brain. Methamphetamine is closely related chemically to amphetamine, but the central nervous s...
In this study, we measured the urine concentrations of methamphetamine and amphetamine as metabolites of selegiline after ingestion of an overdose of selegiline. A patient who had developed Parkinson disease took selegiline in a suicide attempt. Analysis by gas chromatography-mass spectrometry (GC-MS)...

and 10% as amphetamine. Approximately 70% of a single oral dose is excreted in the urine within 24h (Cook et al., 1993; Kim et al., 2004). With repeated dosing, methamphetamine can accumulate in the urine, with one study showing detection 7 days after a regimen of four daily 10mg ora...
The concentration of the urine matrix did not affect the extraction efficiency. The detection limits of methamphetamine and amphetamine in urine were obtained at 0.03 and 0.07 micrograms/mL, respectively, using gas chromatographic-mass spectrometric analysis operated in the electron impact mode. 展开 ...

Despite the low limits of detection obtained with pure amphetamine-like substances, the limits of detection in urine are of the order of 250–500 ng mL−1 which is close to the standard immunoassay cutoff value (300 ng mL−1). Sign in to download full-size image Figure 2. Separation ...
