FAQs

Mass spectrometry relies on precise ion control and measurement, where even small fluctuations in voltage can impact accuracy, resolution, and repeatability of results. High ripple or unstable power can introduce noise, reduce sensitivity, and compromise data integrity.

To address these challenges, XP Power’s mass spectrometry power solutions deliver ultra-low ripple down to 2 PPM and exceptional stability, enabling more accurate measurements and consistent analytical performance in demanding mass spectrometry applications.

As mass spectrometry systems shrink and operate at higher throughput, accuracy increasingly depends on how precisely power stages switch and stabilize. Fast, well-controlled settling reduces transient errors, minimizes noise, and improves measurement consistency at the ion source and detector.

XP Power’s compact, high performance solutions provide rapid switching that lets systems cycle voltages more quickly and reliably. This enables more samples to be processed in the same amount of time, boosting overall throughput while maintaining the precision and long‑term reliability system designers expect.
