The Agilent QTOF 6540 is equipped with exchangeable ESI/APCI ion sources. The ESI source is the JetStream source. The instrument is capable of MS and MS/MS and it is using MassHunter software for data acquisition and processing. LC pumps can handle up to 8000 psi. Mass Accuracy of better than

Ions are accelerated by an electric field of known strength. This acceleration results in an ion having the same kinetic energy as any other ion that has the same charge. A mass selecting quadrupole and collision quadrupole with time-of-flight device as the second mass selection stage is a hybrid known as a quadrupole time-of-flight mass spectrometer (QTOF MS). [7] [8] Quadrupole-quadrupole-time-of-flight (QqTOF) configurations are also possible and used especially the mass spectrometry of peptides and other Tandem mass spectrometry, also known as MS/MS or MS 2, is a technique in instrumental analysis where two or more mass analyzers are coupled together using an additional reaction step to increase their abilities to analyse chemical samples. A common use of tandem-MS is the analysis of biomolecules, such as proteins and peptides. A methodology for the determination of 17 main cannabinoids by liquid-chromatography coupled with quadrupole time-of flight mass spectrometry (LC/Q-TOF-MS) was developed in this work. The separation of the cannabinoids was done with a C8 reverse-phase column and a mobile phase consisting of acetonitrile and water with 0.1% formic acid. 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.

For analysis, 1 µL sample solution was injected into the GC–MS system. Kovats QTOF-MS data were acquired in positive mode scanning from m/z 100–m/z 1000 with and without auto MS/MS fragmentation. Ionization was Wikipedia (2).

The 6530 delivers the power of high-resolution, accurate-mass MS/MS, so you can be fully confident of your data. Key features.

• Q-TOF mode (MS/MS) • Full spectrum of Product Ions (SIM-TOF) • With high resolution and accurate mass • Selectivity beyond any “triple quad” MRM method • Confirm TOF spectrum without interferences • High sensitivity structural elucidation tool Ideal tool for solving complex analytical problems

Narrow: ~1.3 Da. Use for building or searching MS/MS spectral libraries, to improve quality of unidentified MS/MS spectra, and to increase the score of identified compounds. Disadvantage is lower signal. iv. Medium: ~4 Da. Good for general MS/MS work. Higher signal, risk of chimeric spectra. v. Wide: ~9 Da. Not advised for general use. vi.
