DART-MS for rapid, preliminary screening of urine for DMAA

Area of Science:

• Analytical Chemistry
• Forensic Toxicology
• Pharmacology

Background:

• Dimethylamylamine (DMAA) is a stimulant found in dietary supplements, often marketed for weight loss and athletic performance.
• DMAA is banned by the World Anti-Doping Agency (WADA) due to health risks, including adverse effects and fatalities.
• Accurate and rapid detection methods are crucial for identifying DMAA abuse in supplements and biological samples.

Purpose of the Study:

• To evaluate Direct Analysis in Real Time Mass Spectrometry (DART-MS) for the rapid and direct identification of DMAA.
• To demonstrate the capability of DART-MS in analyzing DMAA in solid supplement samples and in urine.
• To assess DART-MS as a potential screening tool for toxicological investigations.

Main Methods:

• Direct Analysis in Real Time Mass Spectrometry (DART-MS) was employed for sample analysis.
• Solid supplement samples were analyzed directly without prior extraction or preparation.
• Urine samples were analyzed directly to detect DMAA over a 48-hour period.

Main Results:

• DMAA was successfully and rapidly identified in solid supplement samples using DART-MS.
• The presence of DMAA was detected directly in urine samples up to 48 hours after administration.
• DART-MS provided unequivocal identification of DMAA due to its speed and the high mass accuracy of the time-of-flight mass analyzer.

Conclusions:

• DART-MS is a highly effective and rapid method for the direct identification of DMAA in various matrices.
• The technique eliminates the need for sample preparation, significantly reducing analysis time.
• DART-MS presents a promising alternative screening method for drug abuse and toxicological analysis.
