What we do

Hexisense SA makes instrumentation based on gallium nitride semiconductors, the same tough material that powered the LED lighting revolution. Our first offering, OxyGaN, is built around a chip that combines a traditional total pressure sensor with a proprietary oxygen chemical sensor. Together, these sensors measure total pressure and oxygen partial pressure in vacuum manufacturing.

Features and Benefits

OxyGaN is a drop-in replacement for a pressure gauge that provides both chemical and physical measures of vacuum quality from high to rough vacuum — where mass spectrometers would require differential pumping — at the price of a pressure gauge. These two signals improve the return-on-investment for expensive process equipment by:

• Safeguard your product with in-situ vacuum quality monitoring
• Speed up your freeze-drying process with endpoint detection
• Track vacuum quality over time for predictive maintenance
• Restart your process faster after maintenance or load lock opening

Applications

OxyGaN’s integrated leak detection capability is for application in the following industries:

• Semiconductors
• Thin film coatings
• Freeze-drying / lyophilization of food and pharmaceuticals
• Food packaging
• Research and development
