UPGRADES TO GAS MONITORING SYSTEM
August 1st 2004

Zellweger Analytics has upgraded its MDA Scientific Vertex, a multi-point toxic gas monitoring system for semiconductor fabrication.

Upgrades are based on feedback from customers and make the system more reliable, more secure and easier to use.

The system provides continuous monitoring of highly toxic gases such as the mineral acids and hybrid gases used in semiconductor fabrication manufacture.

It consists of a network of up to 72 fixed point Chemcassette colorimetric sensors and a powerful yet compact computer-based touch-screen control unit.

High sensitivity is provided, along with virtually cross-interference-free detection and clear physical proof of an event.

Improvements include a twin-drive, high-speed control computer, upgrades to the sampling system and new design of rfid tags for foolproof identification of Chemcassette tapes.
