34 Agilent 6200 Series TOF and 6500 Series Q-TOF LC/MS System Concepts Guide
1Overview
Innovative Enhancements in the 6540 and 6538 Q-TOF
and pulser region. The narrowed, cooled and condensed beam
is a key factor in enabling the gain in mass resolution to 40,000
while maintaining excellent sensitivity.
Extended Flight Tube with Enhanced Mirror Technology (EMT)
The second improvement is that the flight tube for the
6538/6540 Q-TOF is now five feet long.
The 1 ppm/C Expansion Coefficient for the Inner Flight Tube
virtually eliminates calibration drift due to flight tube
elongation. The second order temporal focusing ion mirror uses
a high transmission Harp Grid for maximum sensitivity.
New Fast Bipolar Detector
The third innovative enhancement is the new Fast Bipolar
detector. The scintillator is ultra fast and highly efficient. Also,
the new ultra fast response PMT design continues the tradition
of high dynamic range and detector lifetime.
