Analytical study on ethephon residue determination in water by ion-pairing liquid chromatography/tandem mass spectrometry
Ripollés Vidal, Cristina; Marín Ramos, José Manuel; Sancho, Juan V; Lopez, Francisco; Hernandez, Felix Taylor & Francis (2011-11-22)A detailed analytical study on ethephon residue determination in water, making use of ion-pairing liquid chromatography coupled to electrospray tandem mass spectrometry (LC/MS/MS), has been carried out. Ethephon is a plant ... -
Determination of 17b-estradiol and 17a-ethinylestradiol in water at sub-ppt levels by liquid chromatography coupled to tandem mass spectrometry
Ripollés Vidal, Cristina; Ibáñez, Maria; Sancho, Juan V; Lopez, Francisco; Hernandez, Felix Royal Society of Chemistry (2014-06)Steroid estrogens are a group of endocrine disrupting compounds (EDCs) excreted in human urine mainly as glucuronide or sulfate conjugates, which might be converted back into the free estrogens in water. The natural estrogen ... -
Development of sensitive and rapid analytical methodology for food analysis of 18 mycotoxins included in a total diet study
Beltrán Iturat, Eduardo; Ibáñez, Maria; Portoles, Tania; Ripollés Vidal, Cristina; Sancho, Juan V; Yusà, Vicent; Marín, Silvia; Hernandez, Felix Elsevier (2013)A rapid and sensitive method for the determination of 18 mycotoxins in 24 different food matrices has been developed and validated.
