AbstractMassBank is the first public repository of mass spectra of small
chemical compounds for life sciences (<3000 Da). The database contains 605
electron‐ionization mass spectrometry(EI‐MS), 137 fast atom bombardment MS and
9276 electrospray ionization (ESI)‐MSn data of 2337 authentic compounds of
metabolites, 11 545 EI‐MS and 834 other‐MS data of 10 286 volatile natural and
synthetic compounds... hiện toàn bộ
The Orbitrap: a new mass spectrometer Tập 40 Số 4 - Trang 430-443 - 2005
Qizhi Hu, Robert J. Noll, Hongyan Li, Alexander Makarov, Mark Hardman, R. Graham Cooks
AbstractResearch areas such as proteomics and metabolomics are driving the
demand for mass spectrometers that have high performance but modest power
requirements, size, and cost. This paper describes such an instrument, the
Orbitrap, based on a new type of mass analyzer invented by Makarov. The Orbitrap
operates by radially trapping ions about a central spindle electrode. An outer
barrel‐like elec... hiện toàn bộ
Ion mobility–mass spectrometry Tập 43 Số 1 - Trang 1-22 - 2008
Abu B. Kanu, Prabha Dwivedi, Maggie Tam, Laura M. Matz, Herbert H. Hill
AbstractThis review article compares and contrasts various types of ion
mobility–mass spectrometers available today and describes their advantages for
application to a wide range of analytes. Ion mobility spectrometry (IMS), when
coupled with mass spectrometry, offers value‐added data not possible from mass
spectra alone. Separation of isomers, isobars, and conformers; reduction of
chemical noise;... hiện toàn bộ
Proteomics: the move to mixtures Tập 36 Số 10 - Trang 1083-1091 - 2001
Junmin Peng, Steven P. Gygi
AbstractProteomics can be defined as the systematic analysis of proteins for
their identity, quantity and function. In contrast to a cell's static genome,
the proteome is both complex and dynamic. Proteome analysis is most commonly
accomplished by the combination of two‐dimensional gel electrophoresis (2DE) and
mass spectrometry (MS). However, this technique is under scrutiny because of a
failure ... hiện toàn bộ
Solid‐phase microextraction: a powerful sample preparation tool prior to mass spectrometric analysis Tập 39 Số 3 - Trang 233-254 - 2004
György Vas, Károly Vékey
AbstractSample preparation is an essential step in analysis, greatly influencing
the reliability and accuracy of resulted the time and cost of analysis.
Solid‐Phase Microextraction (SPME) is a very simple and efficient, solventless
sample preparation method, invented by Pawliszyn in 1989. SPME has been widely
used in different fields of analytical chemistry since its first applications to
environm... hiện toàn bộ
Methods and limitations of ‘clumped’ CO2 isotope (Δ47) analysis by gas‐source isotope ratio mass spectrometry Tập 44 Số 9 - Trang 1318-1329 - 2009
Katharine W. Huntington, John M. Eiler, Hagit P. Affek, Weifu Guo, Magali Bonifacie, Laurence Y. Yeung, Nivedita Thiagarajan, Benjamin H. Passey, Aradhna Tripati, Mathieu Daëron, Rosemarie E Came
AbstractThe geochemistry of multiply substituted isotopologues
(‘clumped‐isotope’ geochemistry) examines the abundances in natural materials of
molecules, formula units or moieties that contain more than one rare isotope
(e.g. 13C18O16O, 18O18O, 15N2, 13C18O16O22−). Such species form the basis of
carbonate clumped‐isotope thermometry and undergo distinctive fractionations
during a variety of natur... hiện toàn bộ
Monitoring of herbal mixtures potentially containing synthetic cannabinoids as psychoactive compounds Tập 45 Số 10 - Trang 1186-1194 - 2010
Sebastian Dresen, Nerea Ferreirós, Michael Pütz, Folker Westphal, Ralf Zimmermann, Volker Auwärter
AbstractHerbal mixtures like ‘Spice’ with potentially bioactive ingredients were
available in many European countries since 2004 and are still widely used as a
substitute for cannabis, although merchandized as ‘herbal incense’. After
gaining a high degree of popularity in 2008, big quantities of these drugs were
sold. In December 2008, synthetic cannabinoids were identified in the mixtures
which w... hiện toàn bộ
