High Voltage Power for Mass Spectrometry

Posted July 26, 2016 12:00 AM by SavvyExacta
Pathfinder Tags: mass spectrometry

In mass spectrometry, high-accuracy, high-resolution sample analysis correlates closely with high-performance high voltage. High voltage not only plays a critical role in the ion creation and acceleration phase, but all the way through separation, detection, measurement, and analysis. Performance failure at any phase could jeopardize the entire sample run.

Different tool architectures can be optimized with the right high voltage power supplies and amplifiers. High voltage power supply integration is important to all system elements.

Accuracy and resolution can be significantly improved by correctly matching a high voltage system with the task at hand.

I do not know much on the subject. But I used to repair the high voltage power supply. Most spectrometers I worked use Toshiba make triode valves, and in most cases the Door-knob capacitor used fail. Though Solid semiconductor technology developed a lot, not much in high voltage power supplies suitable for Spectrometry. I also worked (repairing) on XRF equipment that use high voltage for X-rays; using only solid semiconductor technology, but very low power.

I worked with XRF instrumentation for many years. Failure of the X-ray power supply (typically 50 kV) and the x-ray tube were the main system failures and it goes without saying - the most expensive. Unfortunately we found it necessary to offer only 6 months warranty on the tubes. Rapid shipping of a heavy HV PS abroad at short notice and installation by an engineer was a very expensive process - taking away much of the sales profit.
