Jan 1, 2007 · Gas chromatography (GC) coupled to time-of-flight mass spectrometry (TOF-MS) offers unique solutions for various analytical applications including the analysis of food quality, authenticity and safety markers.

Gas chromatography with quadrupole time-of-flight mass spectrometry (GC/Q-TOF) is a highly versatile tool capable of doing routine chemical quantification of regulated compounds while also performing non-targeted identification of emerging pollutants in environmental samples.

Overview of how Agilent’s GC/MS systems work: • GC/single quad (GC/MSD SQ) • GC/triple quad (GC/MS TQ) • GC/quadrupole time-of-flight (GC/MS Q-TOF) Overview of how customers use each type to solve their analytical problems • Example: Pesticides in essential oils

Zoccali highlights how GCxGC-ToF MS enhances the detection of contaminants and key compounds, such as antioxidants and sterols, which are essential for assessing quality, authenticity and flavor. Learn more with our latest TOF-MS application notes. Watch our most recent videos on TOF-MS.

Quadrupole time-of-flight mass spectrometry (Q-TOF-MS) has gained considerable attention over the last decade as an analytical technique that is capable of meeting the challenges of a rapidly changing drug landscape.

In the current paper we describe an automatic GC×GC-TOF-MS procedure to screen organisms with low metabolic capacity (crustacean) for brominated (natural) products.

Time-of-flight mass spectrometry (TOF MS) was developed in the late 1940’s, but until the 1990’s its popularity was limited. Recent improvements in TOF technology, including orthogonal acceleration, ion mirrors (reflectron), and high-speed electron-ics, …

Benchtop GC-TOFMS time-of-flight mass spectrometer for GC and GCxGC, providing confident identification of targets and non-targets in a single analysis.

Jun 1, 2021 · Comprehensive two-dimensional gas chromatography coupled to mass spectrometry (GC×GC-MS) has become a mature technique. GC×GC-MS can now be used to conduct large scale studies, giving full access to its high-resolution power for targeted and mostly untargeted screening.

The GC/Q-TOF is capable of more easily preserving the molecular ion of an analyte during ionization, while also providing valuable fragmentation data. This powerful combination results in more accurate identification of unknowns in a sample.
