Application Notes
DeTech Model 2300 Plug-In Element
for all Agilent Mass Spectrometers
Vented Anode
Grid
Robust Design
Detector Technology, Inc. was the first company to work with
end users to develop a replacement detector for the standard
Agilent Plug-In element. DeTech Model 2300 was designed
to give the end user several performance benefits over the
standard element, as well as a cost benefit.
Lower Operating Voltage – DeTech Model 2300 operates at
a lower voltage than the standard Agilent element. The tuning
voltage of Model 2300 is typically 1100V - 1300V. By starting detector operation at a lower voltage the overall lifetime
is increased.
DeTech Model 2300 Performance Benefits
Increased Signal : Noise – When using Model 2300 in an
Agilent instrument the signal to noise ratio of the instrument
is increased approximately 25%. This is due to the mechanical design changes incorporated into the product, as well as
the optimized channel length.
Vented Anode – Detector Technology, Inc. has added vent
holes to the anode of the detector. These vent holes allow for
residual gases in the detector channel and anode to be
removed during pumping. By removing these gases the performance and life of the detector is improved.
Grid – When input ions enter the horn of a detector secondary electrons are created. These electrons should travel down
the channel of the detector, but occasionally the secondary
electrons travel out of the horn. Detector Technology, Inc. has
placed a grid on the horn causing all secondary electrons to
travel down the detector channel. This increases the signal to
noise ratio and the overall performance of the detector.
Robust Design – DeTech Model 2300 has a robust stainless
steel frame to protect the glass detector from damage.
