Determination of MDMA, MDEA and MDA in urine by high performance liquid chromatography with fluorescence detection.
This paper describes the development and validation of analytical methodology for the determination of the use of MDMA, MDEA and MDA in urine. After a simple liquid extraction, the analyses were carried out on a high performance liquid chromatography (HPLC) in an octadecyl column, with fluorescence detection. The mobile phase using a sodium dodecyl sulfate ion-pairing reagent allows good separa...
متن کاملTraffic fatality related to the use of methylenedioxymethamphetamine.
A recent traffic fatality has been attributed to the use of the drug methylenedioxymethamphetamine (MDMA). The deceased was a 29-year-old white male with no known history of drug abuse. Toxicological analysis detected MDMA and metabolite methylenedioxyamphetamine (MDA) in the blood, urine, and vitreous humor specimens submitted for analysis. The concentrations of MDMA in clotted blood, sodium f...
متن کاملTable 1. CBB-Measured Protein Concentrations (gIL) In Urine SpecImens Diluted to Achieve Bluret-Predicted ProteIn Concentrations
Urine SpecImens Diluted to Achieve Bluret-Predicted ProteIn Concentrations of 4 to 0.2 gIL The Coomassie Brilliant Blue (CBB) dye-binding method for determining total protein in urine is widely used in clinical laboratories because it is sensitive, easily automated, and free from interference by many clinically relevant substances (1-6). However, it yields different results for the same concent...
متن کاملEffectiveness of multiple internal standards: deuterated analogues of methylenedioxymethamphetamine, methylenedioxyamphetamine, methamphetamine, and amphetamine.
With the increasing abuse of methylenedioxymethamphetamine (MDMA) thereby requiring analysis, we have undertaken a systematic evaluation on parameters associated with the analysis of MDMA and related compounds, including methylenedioxyamphetamine (MDA), methamphetamine (MA), and amphetamine (AM). Parameters studied included three solid-phase adsorbents, five derivatization reagents, and four de...
متن کاملSensitive gas chromatography-mass spectrometry method for simultaneous measurement of MDEA, MDMA, and metabolites HMA, MDA, and HMMA in human urine.
BACKGROUND A sensitive gas chromatography-mass spectrometry method was developed and validated for the simultaneous measurement of MDEA, MDMA, and its metabolites, 3,4-methylenedioxy-N-ethylamphetamine (MDEA), 3,4-methylenedioxymethamphetamine (MDMA or Ecstasy), and its metabolites, 4-hydroxy-3-methoxyamphetamine (HMA), 3,4-methylenedioxyamphetamine (MDA), and 4-hydroxy-3-methoxyamphetamine (HM...
