Combined Use of GC-TOF MS and UHPLC-(Q)TOF MS To Investigate the Presence of Nontarget Pollutants and Their Metabolites in a Case of Honeybee Poisoning
Portoles, Tania; Ibáñez, Maria; Sancho, Juan V; Lopez, Francisco; Hernandez, Felix American Chemical Society (2009)The combined use of gas chromatography (GC) and ultrahigh-pressure liquid chromatography (UHPLC), both coupled to time-of-flight mass spectrometry (TOF MS), has been explored in this work for the investigation of several ... -
Determination of eight nitrosamines in water at the ng L−1 levels by liquid chromatography coupled to atmospheric pressure chemical ionization tandem mass spectrometry
Ripollés Vidal, Cristina; Pitarch, Elena; Sancho, Juan V; Lopez, Francisco; Hernandez, Felix Elsevier (2011-09-19)In this work, we have developed a sensitive method for detection and quantification of eight N-nitrosamines, N-nitrosodimethylamine (NDMA), N-nitrosomorpholine (NMor), N-nitrosomethylethylamine (NMEA), N-nitrosopirrolidine ... -
Determination of methylisothiocyanate in soil and water by HS-SPME followed by GC-MS-MS with a triple quadrupole
Peruga Mínguez, Aránzazu; Beltran Arandes, Joaquin; Lopez, Francisco; Hernandez, Felix Springer (2014-09)Methylisothiocyanate (MITC) is the main degradation product of metam sodium, a soil disinfectant widely used in agriculture, and is responsible for its disinfectant properties. Because MITC is highly toxic and volatile, ... -
Determination of PBDEs in human breast adipose tissues by gas chromatography coupled to triple quadrupole mass spectrometry
Pitarch, Elena; Medina, Cecilia; Lopez, Francisco; Hernandez, Felix Springer Verlag (2008)The potential of gas chromatography / tandem mass spectrometry with triple quadrupole analyzer for determination of 12 polybrominated diphenyl ethers in human breast tissues has been investigated. After extraction with ... -
