Environmental applications of membrane introduction mass spectrometry.
The purpose of this review is to highlight the versatility of membrane introduction mass spectrometry (MIMS) in environmental applications, summarize the measurements of environmental volatile organic compounds (VOCs) accomplished using MIMS, present developments in the detection of semi-volatile organic compounds (SVOCs) and forecast possible future directions of MIMS in environmental applicat...
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.
متن کاملOzone modulation of volatile hydrocarbons using membrane introduction mass spectrometry.
A new method that we describe as chemical modulation of volatile hydrocarbons is investigated using ozonolysis pretreatment and membrane introduction mass spectrometry (MIMS). This extension to the MIMS technique is intended to enhance the selectivity of MIMS for measuring hydrocarbons in the complex mixtures often encountered in polluted air samples. The test samples for this study were dilute...
متن کاملA Novel Composite Membrane for pH Responsive Permeation
Objective(s) In this study, a kind of pH sensitive composite membrane was prepared and drug permeation through it was investigated in terms of pH. Rationale of this study originated from the fact that a pH change which may be a result of a disease state in the body can trigger drug release. Materials and Methods Here, a kind of pH sensitive composite membrane containing different nanoparticle ...
متن کاملSodium Laurate, a Novel Protease- and Mass Spectrometry-Compatible Detergent for Mass Spectrometry-Based Membrane Proteomics
The hydrophobic nature of most membrane proteins severely complicates their extraction, proteolysis and identification. Although detergents can be used to enhance the solubility of the membrane proteins, it is often difficult for a detergent not only to have a strong ability to extract membrane proteins, but also to be compatible with the subsequent proteolysis and mass spectrometric analysis. ...
