Detector Technology: Multipliers for Agilent

DeTech Multipliers for Agilent

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.

DeTech Model 2300 Performance Benefits

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.

Lower Operating Voltage – DeTech Model 2300 operates at a lower voltage than the standard Agilent element. The tuning voltage of Model 2300 is typically 1000V - 1200V. By starting detector operation at a lower voltage the overall lifetime is increased.

Increased Signal : Noise Ratio – 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.

Robust Design – DeTech Model 2300 has a robust stainless steel frame to protect the glass detector from damage.
