Gas purity analysis is an important aspect of bulk and specialty gas production, and affects a number of industries including petrochemical, biotech, and electronics manufacture. Understanding the concentration of gases in a mixture and monitoring for the introduction of impurities has often required the use of complex separation and multiple detection methods. Fast sampling is a critical safety requirement in the measurement of highly toxic or explosive compounds.
The SVGA-100 is the world’s first streaming gas detector using vacuum ultraviolet (VUV) spectroscopy for real-time quantitative analysis. The detector was engineered to instantaneously monitor purity and concentration of gas streams. No prior compound separation by gas chromatography is necessary in this update to the VGA detector platform pioneered by VUV Analytics. The SVGA-100 features a multi-port sample selection valve with inputs for up to four gases.
Typically one reference and three sample gases are connected into these ports, but all can be used for sampling and monitoring. The detector software allows for quick toggling between samples (<1 sec), enabling rapid sampling and short analysis times. The ability to monitor gases in real-time presents a unique, high-throughput solution for determining identity and concentration which is unmatched by alternative methods that require multiple detectors and/or long runtimes. Site safety is also significantly improved by being able to quickly analyze highly toxic or explosive compounds with one detector.
