Beschreibungen/Notizen

• Easy sonic-spray ionization mass spectrometry (EASI–MS) allows for direct and fast MS analysis of samples in ambient conditions with little or no sample preparation, therefore offering unprecedented simplicity, speed, and ease of use. EASI–MS has been shown to access the quality, type, and adulteration of biofuels and vegetable oils. Herein, EASI–MS is shown to quantitate and monitor the quality of soybean biodiesel/petrodiesel (Bn) blends. For adulteration, admixture of the parent oil has been tested and nearly instantaneous and direct EASI­(+)–MS detection of as little as 1% (w/w) of soybean oil in biodiesel/petrodiesel blends was achieved. Linear analytical curves (r > 0.98) were also obtained for the quantitation of Bn blends, and the EASI­(+)–MS quantitation results were compared to those obtained by nuclear magnetic resonance (NMR) spectroscopy and mid-infrared (IR) spectroscopy.
