Mass spectrometry for monitoring micropollutants in water.
Surface water reservoirs and aquifers are exposed to contamination by thousands of micropollutants from industrial, pharmaceutical, agricultural and natural origins. Most developed and developing countries implement a water-quality regulation programme to prevent contamination by such chemicals at illegal concentrations. Traditionally, analytical methods based on gas chromatography-mass spectro...
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 enzyme catalysis with mass spectrometry.
Mass spectrometry is a rapid, sensitive, and accurate quantitative approach for the direct monitoring of enzyme-catalyzed reactions that does not require a chromophore or radiolabeling and thus provides a viable alternative to existing analytical techniques. In this study the proteolysis of intact viral capsid proteins, the alpha-glucosidase-catalyzed hydrolysis of p-nitrophenyl-alpha-glucopyra...
متن کاملProviding Complete Mass Spectrometry Solutions
Mass spectrometry is a powerful analytical tool for chemical analysis and life sciences. It can be used to identify unknown compounds, to quantify known compounds, and to obtain information about chemical structure. The ability of mass spectrometry to do all of this for minute amounts of chemicals—often less than a billionth of a gram—make it a highly useful analytical technique in both establi...
متن کاملCharge monitoring cell mass spectrometry.
An instrument to directly measure the charge carried by a cell or a microparticle as well as mass-to-charge ratio of the cell/microparticle was developed for rapid mass distribution measurement. A successful mass spectrum with a record high mass has been demonstrated. In this article, the details of the construction and operation of the charge monitoring cell mass spectrometer are reported. Exa...
