Residue determination of glyphosate, glufosinate and aminomethylphosphonic acid in water and soil samples by liquid chromatography coupled to electrospray tandem mass spectrometry.
The use of labelled glyphosate as internal standard allowed improving the recovery and precision for glyphosate and AMPA, while it was not efficient for glufosinate, that was quantified by external standards calibration. Expand
Fast determination of 40 drugs in water using large volume direct injection liquid chromatography-tandem mass spectrometry.
A rapid analytical method based on direct sample injection of water samples for the simultaneous identification/quantification of 40 emerging compounds, including pharmaceuticals and drugs of abuse, showing good recoveries and precision is described. Expand
UHPLC–MS/MS highly sensitive determination of aflatoxins, the aflatoxin metabolite M1 and ochratoxin A in baby food and milk
Abstract In this work, a method has been developed for the ultrasensitive and selective determination of various regulated mycotoxins (aflatoxins G1, G2, B1, B2, M1, and ochratoxin A) in baby foodExpand
Rapid non-target screening of organic pollutants in water by ultraperformance liquid chromatography coupled to time-of-light mass spectrometry
We show the potential of ultra-performance liquid chromatography (UPLC) coupled to time-of-flight mass spectrometry (TOF-MS) for screening of non-target organic pollutants in water samples. The greatExpand
Antibiotic residue determination in environmental waters by LC-MS
Pharmaceuticals, identified as emerging contaminants, are used in large quantities in human and veterinary medicine for treatment of different diseases. Among pharmaceuticals, antibiotics in theExpand
Simultaneous ultra-high-pressure liquid chromatography-tandem mass spectrometry determination of amphetamine and amphetamine-like stimulants, cocaine and its metabolites, and a cannabis metabolite in
The wastewater treatment plants showed good removal efficiency for low levels of illicit drugs in water, but some difficulties were observed when high drug levels were present in wastewaters. Expand
Determination of mycotoxins in different food commodities by ultra-high-pressure liquid chromatography coupled to triple quadrupole mass spectrometry.
A rapid multianalyte-multiclass method with little sample manipulation has been developed for the simultaneous determination of eleven mycotoxins in different food commodities by usingExpand
Re-evaluation of glyphosate determination in water by liquid chromatography coupled to electrospray tandem mass spectrometry.
An analytical method based on on-line solid-phase extraction-liquid chromatography coupled to electrospray tandem mass spectrometry (SPE-LC-ESI-MS/MS) for the determination of glyphosate andExpand
Removal of emerging contaminants in sewage water subjected to advanced oxidation with ozone.
Ozone treatments have been proven to be highly efficient in the removal, notably decreasing the concentrations for most of the emerging contaminants present in the water samples, and the use of ultrasounds has been shown less effective, being practically unnecessary. Expand
Development of sensitive and rapid analytical methodology for food analysis of 18 mycotoxins included in a total diet study.
The developed methodology was applied to the analysis of 240 samples within a total diet study performed at Comunidad Valenciana (Spain), and the most frequently found mycotoxins were deoxynivalenol, fumonisin B1, ochratoxin A and zearalenone at low μg kg(-1) levels. Expand
