Screening for Emerging Chemical Contaminants in Water Using LC/Q-TOF and Mass Profiler Professional Software Authors

چکیده
The Agilent 6540 Q-TOF LC/MS and Agilent Mass Profiler Professional Software (MPP) were used to sensitively characterize the complex chemical composition of municipal wastewater. The processing of Q-TOF high-resolution MS data using the MPP multivariate statistical analysis package revealed changes in the occurrence patterns of organic chemicals during water treatment. Using this technique, we were able to determine which organic contaminants were attenuated, resilient, and formed during ozonation of recycled water. Heat maps created in MPP provide patterns that can be used to assess subtle changes in water quality and to identify emerging contaminants unique to a particular water or treatment process.

Olive Oil Characterization using Agilent GC/Q-TOF MS and Mass Profiler Professional Software Authors
A model was constructed that predicts whether an olive oil will pass the extra virgin sensory test. Using the Agilent 7890A GC system coupled to the Agilent 7200 series accurate-mass Q-TOF MS in both electron ionization (EI) and positive chemical ionization (PCI) modes, a large number of compounds was found in olive oil. Mass Profiler Professional software was used to perform statistical analys...

متن کاملImmunomagnetic microbeads for screening with flow cytometry and identification with nano-liquid chromatography mass spectrometry of ochratoxins in wheat and cereal
Multi-analyte binding assays for rapid screening of food contaminants require mass spectrometric identification of compound(s) in suspect samples. An optimal combination is obtained when the same bioreagents are used in both methods; moreover, miniaturisation is important because of the high costs of bioreagents. A concept is demonstrated using superparamagnetic microbeads coated with monoclona...
