Recommended Shut Down Procedure for Agilent TOF/QTOF. In response to the COVID-19 crisis many customers are contacting Agilent for recommendations in shut down procedures. If you have an uninterrupted drying gas source (N2 generator) we recommend the you put the system into Standby. If you have an interrupted drying gas source (dewars) we

The ability to confidently detect specific target compounds is critical in many analytical workflows related to human health and safety. In some cases, such screening is challenged by the physical form of the samples and by the chemical nature of the targets themselves. In this study, pyrolysis GC-APCI QTOF MS is used to detect potentially hazardous plasticizers and flame retardants in various

All IEMs were unambiguously established/diagnosed using this new QTOF method by evaluation of the panel of 71 biomarkers. In conclusion, we present a LC-QTOF/MS method for fast and Quadrupole time-of-flight (QTOF) MS has revolutionized how we identify and quantify complex mixtures and unknown compounds, in fields ranging from biological and pharmaceutical research to clinical toxicology. Our ultra-high resolution QTOF and LC-QTOF instruments are at the leading-edge of this technology.

For suspect screening, extracts were rerun in electron ionization (EI) mode with a retention time locked method using a GC-QTOF-MS pesticide library (containing exact mass fragments and retention times). Using GC-TOF-MS, 571 peaks were extracted, of which 189 metabolites were tentatively identified.

A common use of tandem-MS is the analysis of biomolecules, such as proteins and peptides. Thermo desorption two-dimensional quadrupole-time-of-flight mass spectrometry (TD-GCxGC-QTOF-MS) is used for accurate analysis of highly-complex volatile mixtures in ultra-low concentrations and/or of un-known identity. This instrument is part of the headspace facility. The other part of this facility is the high-throughput headspace sampling facility (klick button below). In this study, pyrolysis GC-APCI QTOF MS is used to detect potentially hazardous plasticizers and flame retardants in various fabric samples.
