Sigma 4000 Multipoint Stream Selector

At AMETEK Process Instruments, we focus our experience on designing new, innovative analyzers that help our customers achieve higher levels of productivity and quality. We do this by seeking out ways to overcome the limitations of current methods of process monitoring, control, and quality assurance. It is through this focus that we have created some of the most unique and capable technologies in the world.

 

Our primary focus in analyzer design is reliability. We understand that you must have confidence that the analyzer will provide the correct information when you need it. It is a documented fact that many of our analyzers have been in service for well over 20 years.

 

Sigma 4000 Multipoint Stream Selector


  

The Need
Proper monitoring of the purity of the process gases which feed semiconductor manufacturing equipment and processes requires monitoring at multiple sample points. However, placing individual gas purity analyzers at all these sample points can be very expensive.
  
The Solution
Sigma 4000 multipoint stream selectors from Trace Analytical can dramatically reduce the cost of ultra high purity (UHP) gas monitoring. By multiplexing several sampling points to a single ta3000 or ta5000 Process Gas Analyzer, a gas manager can ensure that UHP quality product is supplied to process tools without dedicating an instrument to each gas stream. Controlled by the gas chromatograph, a Sigma 4000 stream selector can poll several gas streams in sequence, or can be programmed to switch between the inlets and outlets of large scale purifiers to verify their performance.

Sigma 4000 multipoint stream selectors improve the confidence in your gas supply by making it practical to monitor impurities such as H2, CO, CO2, CH4 and THC's in all of your most critical gas streams.
