Analyzers 1-13
Ion optics overview
Analyzers
The system uses both quadrupole and time-of-flight (TOF) mass analyzers.
You can use the TRAP T-Wave and TRANSFER T-Wave regions of the
Triwave device for fragmentation analyses.
Quadrupole
The quadrupole is available with 4, 8, and 32 kDa mass range options, and
you can operate it in the following modes:
• Without applying the resolving dc voltage – A broad mass-to-charge
range of ions passes through, and the TOF analyzer accurately
measures their mass (MS acquisition).
• Applying the resolving dc voltage and selecting a specific mass.
• With the instrument automatically switching between MS and MS/MS
modes – known as Data Directed Analysis (DDA™), this operation
depends on the ions detected in an MS scan.
