  • Trace-Level UV Fluorescence SO2 Analyzer

    Model T100U - Teledyne Advanced Pollution Instrumentation

    The Model T100U Trace-level SO2 analyzer has been developed specifically to address the challenges of low level monitoring as required, for example, in the US NCore network. It uses the proven UV fluorescence principle, and is designed to allow ultra-sensitive SO2 measurements while still meeting the requirements for use as a US EPA compliance analyzer.The analyzer uses both the light and dark phases of the pulsed UV light source to continuously detect and correct for electronic noise, giving exceptionally stable and sensitive performance. A separate UV detector allows the instrument to continuously correct for variations in lamp intensity. Exceptional stability is achieved with the use of an optical shutter to compensate for PMT drift, and a reference detector to correct for changes in UV lamp intensity. A hydrocarbon "kicker" and advanced optical design combine to prevent inaccuracies due to interferents.
