Detection of nitroxyl (HNO) by membrane inlet mass spectrometry.
Membrane inlet (or introduction) mass spectrometry (MIMS) was used to detect nitroxyl (HNO) in aqueous solution for the first time. The common HNO donors Angeli's salt (AS) and Piloty's acid (PA), along with a newly developed donor, 2-bromo-N-hydroxybenzenesulfonamide (2-bromo-Piloty's acid, 2BrPA), were examined by this technique. MIMS experiments revealed that under physiological conditions 2...
متن کاملMembrane inlet mass spectrometry for homeland security and forensic applications.
A man-portable membrane inlet mass spectrometer has been built and tested to detect and monitor characteristic odors emitted from the human body and also from threat substances. In each case, a heated membrane sampling probe was used. During human scent monitoring experiments, data were obtained for inorganic gases and volatile organic compounds emitted from human breath and sweat in a confined...
متن کاملOil-in-water monitoring using membrane inlet mass spectrometry.
A membrane inlet mass spectrometry (MIMS) system has been used for detection and analysis of two types of North Sea crude oil. The system was installed on-field on the Flotta Oil Terminal (Orkney, UK). It consisted of a quadrupole mass spectrometer (QMS) connected to the capillary probe with a silicone-based membrane. The produced mass spectra and calibration plots from the MIMS instrument show...
متن کاملMonitoring of human chemical signatures using membrane inlet mass spectrometry.
This work is an attempt to assist border security crackdown on illegal human immigration, by providing essential results on human chemical signatures. Data was obtained using a portable quadrupole mass spectrometer coupled with a membrane probe for volunteers of both genders and under different conditions in a container simulator. During experiments, participants were asked to follow various pr...
متن کاملOn-line monitoring of bioreductions via membrane introduction mass spectrometry.
Real-time and on-line continuous monitoring of reactants, intermediates, and final products for dicarbonyl compound bioreduction in a continuous plug flow reactor packed with baker's yeast (Saccharomyces cerevisiae) whole cells immobilized on calcium alginate beads was performed by membrane introduction mass spectrometry (MIMS) via selective ion monitoring.
