Ambient Air

Ambient Air

CAS is proud to offer Gas Chromatographs (GC) for continuous monitoring of air toxics (VOCs), and speciated sulfur compounds in ambient air. Utilizing real time GC technology, this platform is fully autonomous and field proven, incorporating advanced techniques and state of the art instrumentation. Over the past two decades, the CAS supplied field GC’s have been thoroughly evaluated in various locations against current standards to show conformity. Furthermore, real-time GC monitoring systems are capable of measuring PAMs, TO-14A and European Norm target VOC compounds (including benzene, 1,3-butadiene, styrene). These systems are now operating successfully in multiple locations throughout North America.
