Fast, Sensitive, and Reliable Hydrocarbon Measurements in Ambient Air

Aug 11 2020 Read 1689 Times

Teledyne API provides a complete line of ambient air quality monitoring instruments for both gas and particulate pollution, as well as gas calibration instruments, that help ensure consistently high data quality to government agencies, consultants, industrial facilities, and institutions around the world.

One of Teledyne API’s latest product innovations, the Model N901, is a near-continuous (1-min cycle time) hydrocarbon gas analyser that measures the concentration of Methane (CH4) and Total Hydrocarbons (THC) in air. The concentration of the non-Methane hydrocarbons (NMHC) component is calculated by the subtraction of CH4 from THC, with high sensitivity and accuracy. The hydrocarbons are measured using a robust Flame Ionization Detector (FID), in combination with patented gas chromatography (GC). The instrument's range and performance are tuned specifically for use in ambient air quality monitoring assessments, , including perimeter (or fenceline) air monitoring and community assessment projects for oil and natural gas (O&NG) production operations.

Certain industrial facility processes in these applications result in fugitive emissions into the ambient air and surrounding communities. These emissions can be precursors to ground-level ozone formation and can have negative health impacts directly. Performing ambient air quality monitoring using the best technology is critical to mitigating these fugitive emissions and other air pollutants that are regulated by many developed countries around the world, in order to protect the public and the environment.

The Model N901 is designed for simple operation and maintenance with a modular hardware and state-of-the-art electronics architecture. A long-life stainless-steel fritted filter is used at the sample intake to effectively remove particulate matter without introducing any gas-phase measurement artifacts. Instrument operation, calibration functions, chromatogram views,​ and data handling are all automated and controlled using the internal NumaView™​ Software interface, without the need for an external PC.​

For remote connection to the N901 instrument, Teledyne API’s NumaView™ Remote PC-based Software provides a virtual interface, instrument controls, and data downloading capability to all TAPI analyzers operating NumaView™ Software.

All of Teledyne API’s products include advanced communications capabilities that are designed to integrate seamlessly into other external data systems, providing real-time and transparent access to any instrument data or other diagnostic parameters.
