Customer Use Application
The Department of Environmental Toxicology at the University of California Davis uses a custom Zaber T-NA08A25 actuator as part of a custom-built mass spectrometer. The mass spectrometer was developed to measure trace gases in the atmosphere, with relevance to the study of air pollution and climate change. The Zaber actuator is mounted on the ion source housing of the spectrometer using aluminum parts that were machined especially for its dimensions. The linear motion of the actuator pushes a compressible bellows, which drives the slider to cover or expose the inlet pinhole to let in ionized ambient air into the mass analyzer.
