F-2 Performance Specifications
Performance specifications
Mass range
4000 Dalton.
Resolution
7000 resolution (FWHM) at m/z 614.
Acquisition rate
Up to 20 full spectra (to m/z 800) per second in normal mode.
Up to 10 full spectra (to m/z 800) per second in DRE extended mode.
GC sensitivity
EI positive ionization mode
1 pg of hexachlorobenzene (m/z 283.8) will give a peak to peak signal-to-noise
ratio (S:N) >10:1 while acquiring full spectra over a mass range up to m/z 800.
CI positive ionization mode
100 pg of benzophenone (m/z 183.1) will give a S:N >150:1 while acquiring full
spectra over a mass range up to m/z 800.
CI negative ionization mode
1 pg of octafluoronapthalene (m/z 272.0) will give a S:N >100:1 while acquiring
full spectra over a mass range up to m/z 800.
Mass accuracy
When a suitable peak of known mass is used as an internal reference, the
RMS error between the measured and calculated mass is less than 1 mDa for
measurements below m/z 200, and is less than 5 ppm for measurements above
m/z 200. Peaks are required to have sufficient intensity and be free from
interference from other masses.
