Orthogo-TOF
Orthogonal Acceleration/Extraction TOF (oaTOF)
Time Of Flight Mass Spectrometer Components
From
Jordan TOF Products, Inc.
Formerly
R. M. Jordan Co., Inc.

Instrument Features:

Designed specifically to do TOFMS with ions created from an external source.

Modular. Easy to maintain, upgrade.

Existing Jordan TOF instruments can be easily retrofitted to Orthogo-TOF.

Designed to work with virtually any source of externally generated ions.

Extraction region is differentially pumped. Two orders of magnitude of vacuum differential from chamber to extraction source/flight tube can be obtained with a relatively small turbo pump on flight tube sideport (250 lps typical).

Flight tube can be rotated to one of four positions for desired sideport/pump location, and still maintain proper reflector alignment.

Can be used in both linear and reflected modes (oaTOF and oaRETOF).

Orthogonal Acceleration/Extraction Source Features:

Deflection/Focusing optics tilted parallel to ion beam.

Split tube beam deflector designed to correct/steer ion beam with very high initial energies into the oaTOF with minimal loss of performance.

Different pulser configurations can be used.
Repelling (push out electrode/POE) pulse only
Extraction pulse only
Repeller (POE) and Extractor pulsed simultaneously (dual polarity/push pull)

Different entrance optics available.
Focusing optics/Collimator
Skimmer/Collimator for ions or neutrals (internal ionization).
Collimator only.

Extraction shroud/shield has access ports for pass thru to EMT, installation of electron gun ionizer, or laser beam/VUV entry for internal ionization.
