Overview

Measurement of C2H4O, CO2, CH4 and H2O

Product Details

In Picarro's ethylene oxide (EtO) gas concentration analyzer series, the G2920 environmental analyzer uses a platform that supports long-term monitoring of fugitive emissions at fences and EtO concentrations in community environments. In applications that require accurate and real-time quantification of EtO emissions, Picarro outperforms traditional techniques such as Fourier transform infrared spectroscopy (FTIR) or gas chromatography (GC). The quantification of fugitive EtO emissions from industrial facilities has never been so simple.

  • Best in class sensitivity (ppt level detection limit), specially designed to meet the strictest regulatory requirements

  • Real time measurement can be used for real-time emission detection (seconds)

  • Excellent stability and continuous operation can minimize downtime and reduce data loss to the greatest extent possible

  • Easy to operate, no need to use any consumables, no need for pre enrichment, thus reducing the cost of ownership

  • Small footprint, can be installed in minutes, and can be deployed in various new application scenarios

High quality stainless steel components, working temperature of 80 ℃, and small volume of key gas channels reduce the possibility of C2H4O molecules adsorbing onto the channel surface, shorten the measurement response time (<10='' seconds), and eliminate measurement deviation. In addition, this analyzer can accurately measure carbon dioxide (CO2), methane (CH4), water vapor (H2O), and other volatile organic compounds (VOCs), ensuring interference free operation of the instrument. The analyzer adopts a portable structure, which is convenient for fixed or mobile deployment (rack can be used), thus achieving on-site activities that have not been feasible so far. The analyzer is equipped with a multi port sampling system, which can characterize air quality from various sources, surpassing the limitations of existing technologies (such as FT-IR) and expanding its service range. With the addition of g2920, picarro now provides a range of easy to integrate solutions for service providers, regulatory agencies, and researchers into the next generation
