Direct and Convenient Mass Spectrometry Sampling with Ambient Flame Ionization
Recent innovations in ambient ionization technology for the direct analysis of various samples in their native environment facilitate the development and applications of mass spectrometry in natural science. Presented here is a novel, convenient and flame-based ambient ionization method for mass spectrometric analysis of organic compounds, termed as the ambient flame ionization (AFI) ion source...
متن کاملAnalysis of Polybrominated Dephenyl Ether Flame Retardants by Gas Chromatography/Mass Spectrometry
Polybrominated diphenyl ethers (PBDEs), commonly used flame retardants, are under scrutiny as a result of their global presence and rapid bioaccumulation. Legislative and commercial groups have initiated programs to reduce or eliminate specific PBDE congeners as a result of their potential health threat. This application note will demonstrate a gas chromatography/mass spectrometry (GC/MS) analy...
متن کاملFlame-Retardants and Other Organohalogens Detected in Sewage Sludge by Electron Capture Negative Ion Mass Spectrometry
Numerous halogenated organic compounds have been identified as pollutants of concern. Those with high persistence and hydrophobicity may concentrate in biota, sediments, and wastewater sludge. Nonetheless, the release to the environment of many remains largely unrecognized. Stabilized sewage sludge (biosolids) is increasingly being land-applied as a soil amendment. However, understanding the ri...

متن کاملIdentification of aflatoxins by quadrupole mass spectrometry/mass spectrometry.
MS/MS daughter experiments were recorded for aflatoxins B1, B2, G1, G2, M1, M2, and aflatoxicol, using 3 ionization modes. Daughters were recorded from the molecular ion (M+) using electron impact ionization (EI). Daughters from the protonated molecules (MH+) were recorded in the positive ion mode and the daughters from the molecular anion (M-) were recorded in the negative ion mode using chemi...
