Glass Blister Analyzer for Automated QA/QC
Experience
Since 1985, Extrel has installed Blister Analyzers throughout the world including China, Korea, Malaysia, Germany, Japan, and the USA. Extrel has designed this system to meet the analysis and reporting requirements specified by all the major glass manufacturing companies. At the same time our instruments retain the flexibility to meet the customer specific need for the individual application. We have been providing automated analysis of encapsulated gases for longer, and in a greater variety of applications, than anyone.
Performance
We use a 19 mm high transmission high resolution Quadrupole - the largest and highest performance quadrupole made in the world. It provides better detection limits and precision than the small 6mm quadrupoles used by others. The Blister Analyzer components are identical to the ones used in our high performance process mass spectrometers, having an on-line reliability of better than 98% in continuous use. Furthermore, the small gas load of a Blister Analyzer allows for the use of ion pumps to maintain system cleanliness, eliminate potential oil contamination from typical turbomolecular pump systems, and to provide a vacuum tight system for fast recovery in the event of a power loss.
