XP Power launches advanced mass spectrometry power supplies
XP Power has announced the release of its application-specific Mass Spectrometry power supplies, the MS Source and MS Detector power platforms. The launch of these power supplies responds directly to the increasing need for high resolution, high throughput molecular analysis driven by the expansion of clinical diagnostics, such as newborn screening and oncology, rapid growth in biotech R&D, including drug discovery and genomics for precision medicine, as well as rising regulatory requirements.
As mass spectrometry instruments have evolved, users are increasingly demanding highly repeatable results over extended 16-hour back-to-back work shifts, and higher throughputs. In addition, run-to-run and instrument-to-instrument consistency is now expected across different labs, operators, and deployments not just within a single optimised system.
Both the MS Source and MS Detector series share a robust set of core features designed to simplify integration and guarantee reliable performance. Operating from a standard +24VDC input, both compact, chassis-mount modules offer reversible high voltage outputs. They offer a standard polarity switching time of 25ms, with an optional ultra-fast 5ms version available. The modules also guarantee a low ripple of 0.01%, stability of 100ppm/hr, and a temperature coefficient of 100ppm/°C, ensuring consistent performance over extended shift patterns.
Specifically optimised for ionisation stages like electrospray ionisation (ESI), the MS Source series delivers a reversible output up to ±6kV. On the detector side, components like photomultiplier tubes (PMTs), electron multipliers, or microchannel plates (MCPs), are sensitive to electrical noise, which can compromise analytical results. The MS Detector series delivers a fast-reversible main output up to ±12kV for biasing dynode chains with a secondary adjustable output up to -5kV for powering the multipliers. The unified grounding scheme of the module eliminates low-frequency electrical noise, and reduces system size, wiring complexity, and overall cost.
To aid system diagnostics, the MS Source includes analogue voltage and current monitor outputs, while the MS Detector includes specific pins for Dynode voltage readback and multiplier voltage readback. Designed for safe operation, both feature comprehensive short circuit, arc, and overload protections, and are designed to meet UL61010 safety approvals.
The Mass Spectrometry Platform is available direct from XP Power with a 3-year warranty.
