Mass Spectrometry Power Suplies
The MSRD series consists of high-stability, reversible source modules that perform reliably even under short-circuit or arc conditions. It pairs fast, reversible bias output with a floating +3 kV, 400 μA detector output, offers a differential programming input, and can be set by an external voltage.
The modular design of AE high voltage products for mass spectrometry enables an array of performance features and combinations. From simple options, such as cable length and connector type, to complete custom designs, we deliver solutions that precisely fulfill your specific requirements.
