Impact of oxydoreduction potential on biosynthesis of volatile compounds in acid skim milk gel: identification and quantification
2008
International audience; Oxydoreduction potential (Eh) is an environmental parameter which defines balances between oxidant species (acceptors of electrons) and reduced species (donors of electrons) of a medium. It may modify the growth capacity of microorganisms, the metabolic fluxes, participate to the quality of fermented products (2, 6, 7) and affect the production and/or stability of volatile compounds (3,5).

Halogenated Anesthetics Determination in Urine by SPME/GC/MS and Urine Levels Relationship Evaluation with Surgical Theatres Contamination
2014
In this work, a new sensitive analytical method has been developed and evaluated for the determination of the most commonly used gaseous anesthetics, desflurane, sevoflurane, and this latter’s hepatic metabolite hexafluoroisopropanol (HFIP) in the urine. In addition, an evaluation of anesthetics exposition on the urine levels of a small population of surgical operators has been performed and results are briefly discussed.
