Tof Analyzer - Waters SYNAPT G2 Operator's, Overview And Maintenance Manual

TOF analyzer

The orthogonal acceleration, dual reflectron geometry of the TOF analyzer
provides high resolution and exact mass capabilities. You can operate the
analyzer in the modes described in this table.

Description
Maximum sensitivity using single-pass TOF. In this
mode, the ions travel from the high-field pusher to the
dual-stage reflectron and then to the detector (see the
figure on page 1-16).
Highest resolution using single-pass TOF.
This double-pass TOF mode offers higher resolution
than the single-pass Resolution mode. Ions travel
between the analyzer components in the following
sequence:
• From the high-field pusher to the dual-stage
reflectron.
• From the dual-stage reflectron to the ion mirror.
• From the ion mirror back to the dual-stage
reflectron.
• From the dual-stage reflectron to the detector.
See the figure on page 1-16.
