Zellweger Analytics has made a major upgrade to its MDA Scientific Vertex system - the leading multipoint toxic gas monitoring system for semiconductor fabrication.
Zellweger Analytics has made a major upgrade to its MDA Scientific Vertex system - the leading multipoint toxic gas monitoring system for semiconductor fabrication.
Part of the company's continuous product improvement programme, and based on direct feedback from customers, the upgrades make Vertex even more reliable, more secure and easier to use.
Vertex provides continuous monitoring of highly toxic gases such as the mineral acids and hydrides gasses used in semiconductor fabrication manufacture.
It consists of a network of up to 72 fixed point Chemcassette colorimetric sensors and a powerful but compact computer-based touch-screen control unit.
The system provides high sensitivity, virtually cross-interference-free detection and clear physical proof of an event.
Improvements in the new version include a twin-drive high-speed control computer, upgrades to the air flow sampling system and a new design of the innovative radio frequency identification (RFID) tags for foolproof identification of Chemcassette tapes.
The new Vertex double hard-drive computer system provides a complete mirror of the interactive operating system and data-logging capability for up to 72 separate zones, for complete redundancy.
In the event of a drive failure, the system switches seamlessly to the backup drive, with no loss of data or operating settings.
For maintenance purposes, the drives are "hot-swappable", ensuring continuous system availability, protected by key access.
Microprocessor speed has been increased from 700MHz to 2.6GHz in the new version.
New diagnostics and hardware have been incorporated for monitoring redundant system power supplies, ensuring continuous availability of the installed backup.
New diagnostics have also been added to the pneumatic system for the identification of any problems in the site exhaust lines.
Gas detection performance has been enhanced with the addition of a system vacuum valve for more stable airflow and built-in pump monitoring for reduced maintenance.
Pyrolysers used to detect complex species such as nitrogen trifluoride (NF3) - have a more efficient heating element for faster warm-up times and an improved system power factor.
Zellweger Analytics' unique RFID Chemcassette tags have been further developed and simplified with a new self-alignment system for even better reliability.
This foolproof method ensures maximum safety and confidence in the availability of critical monitoring applications.
The preferred gas detection system for the semiconductor industry, Vertex has an installed base of more than 300 systems worldwide.
Existing users can access all upgrades through an attractive service upgrade package.
