Quadrupole-time-of-flight (QTOF) mass spectrometers are high mass accuracy and high resolution instruments ideal for peptide sequencing in the Information Dependent Acquisition (IDA) mode. Their high resolution is useful for determination of charge state and protein mass measurements in addition to accurate mass determination of biological

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).

Things like screening and accurately quantitating simultaneously, staying calibrated over days…even weeks, and seeing significantly more components in your samples. In MS/MS mode, it is 1,500:1 RMS. Mass resolving power is greater than 45,000 full width at half maximum (FWHM) at m/z 2,722. Mass accuracy in MS mode is less than 0.8 ppm RMS as measured from 10 repeat injections; in MS/MS mode, it is less than 2 ppm RMS on m/z 397 from the same measurement.

Världshistorien och framtiden. - Sven Time-of-flight mass spectrometry (TOFMS) is a method of mass spectrometry in which an ion's mass-to-charge ratio is determined by a time of flight measurement. 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.
