DC Series Enhances Mass Spectrometer Detectors

Applied Kilovolts’s Brandenburg division has released the DC series fast switching power supplies, which offer enhanced performance for mass spectrometer detectors.
The modules are designed for multi-stage detector applications requiring a fast polarity switching dynode and fast settling electron multiplier output.
They are suitable for quadrupole and ion trap mass spectrometers using electron multiplier or photomultiplier detectors.
The modular design can be configured with one to three outputs of up to +/- 15 kV, which can be programmed remotely.
Polarity switching is a fast 10ms (at +/- 5kV).
The use of Dynamic Control technology within the output stages ensures fast and accurate settling after polarity change, with minimal overshoot.
Output is highly stable, with ripple of 500ppm p/p and drift (after one hour warm up) of less than 0.01 per cent an hour.
The modules provide true zero volt crossing and full linear control and include a voltage and current monitor.
They are flashover and short-circuit protected.
The new DC series complements the Brandenburg SC range of fast polarity switching power-supplies designed for source mass spectrometer applications.
