Quantitation of Alprazolam using Ambient Ionisation (DART) Mass Spectrometry

Gas chromatography coupled with mass spectrometry (GC-MS) or high-resolution mass spectrometry (GCxGC-HRMS)  is widely used to identify differences between similar samples. Comprehensive two-dimensional gas chromatography combined with high-resolution mass spectrometry (GCxGC-HRMS) uses two columns with different phases to achieve greater separation of complex mixtures.  Each separation method has its strengths and weaknesses with respect to hardware setup and information content.
