Characterization of the organic contamination pattern of a hyper-saline ecosystem by rapid screening using gas chromatography coupled to high-resolution time-of-flight mass spectrometry
Elsevier (2012-09)In this paper, gas chromatography coupled to high-resolution time-of-flight mass spectrometry (GC–TOF MS) has been applied to evaluate organic pollution in a hyper-saline aquatic environment. Firstly, a target screening ... -
Investigation of pesticide metabolites in food and water by LC-TOF-MS
Elsevier (2008)We illustrate the potential of liquid chromatography with (quadrupole) time-of-flight mass spectrometry [LC-(Q)TOF-MS] in investigating the presence of pesticide metabolites in food and water samples. The higher polarity ... -
Use of soft and hard ionization techniques for elucidation of unknown compounds by gas chromatography/time-of-flight mass spectrometry
John Wiley (2011-05-11)Investigation of trace-level non-target compounds by gas chromatography/mass spectrometry (GC/MS) often is a challenging task that requires powerful software tools to detect the unknown components, to obtain the deconvoluted ...
