CPI electron multipliers for HP GC/MS are designed to give
you several performance benefits over the standard element...
Vented Anode
– CPI multipliers have 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. CPI multipliers have a grid on the front of the horn causing all secondary electrons to travel down the detector channel. This increases the signal-to-noise ratio and overall performance of the
detector.
Lower Operating Voltage –
CPI multipliers operate at a lower voltage than the standard Hewlett Packard element. The tuning voltage is typically 1100V – 1300V. By starting detector operation at a lower voltage overall lifetime is increased.
Increased Signal-to-Noise Ratio– In a Hewlett Packard instrument the signal-to-noise of the instrument is increased approximately 25%. This is due to the mechanical design changes incorporated into the product, such as the vented anode and grid.
Robust Design – CPI multipliers have a robust stainless steel frame to protect the glass detector from damage. |
