Mass spectrometers are mainly used to accurately identify unknown or verify existing compounds. This is done by measuring the weight (mass) of different molecules within a sample. One use of this technique is to detect impurities in samples and is often performed as a continuous operation in industrial process environments.

Developing a mass spectrometer capable of testing multiple samples at once, engineers required six 24V and 30V outputs with output power levels ranging from 120 to 300W. TDK-Lambda proposed a QM5 modular power supply with two dual and two single modules in a compact 700W 127mm wide package. A sample unit was quickly configured and delivered from the local factory.

The QM series was preferred as it offers a very low audible noise, ideal for operation in process development laboratories. The product’s seven-year warranty also was attractive for a low cost of ownership.

TDK-Lambda offers a wide range of test and measurement power supplies. Please click here for more details.
