EPA Method T0-11A EPA outlines practices for measuring formaldehyde using the 4,2-DNPH denuder method, subsequent derivatization, and analysis by HPLC. While the DNPH method has been a stalwart of air quality monitoring for decades, it provides only time-averaged exposure estimates (typically 8 or 24-hour), requires offline analysis at third-party labs, and continues to experience suspected…

Natural gas stoves in >40 million U.S. residences release methane (CH₄)--a potent greenhouse gas--through post-meter leaks and incomplete combustion. We quantified methane released in 53 homes during all phases of stove use: steady-state-off (appliance not in use), steady-state-on (during combustion), and transitory periods of ignition and extinguishment. We estimated that…

A general feature in the diurnal cycle of atmospheric ammonia (NH₃) concentrations is a morning spike that typically occurs around 07:00 to 10:00 (LST). Current hypotheses to explain this morning’s NH₃ increase remain elusive, and there is still no consensus whether traffic emissions are among the major sources of urban NH₃. Here, we confirmed that the NH…

The reduced economic and social activities during the Chinese Spring Festival provide a unique experiment to evaluate reductions in anthropogenic NH₃ emissions in China. However, quantifying this unique scenario is challenging as meteorology may mask the real changes in observed NH3 concentrations. Here, we applied a machine learning technique to decouple the effects of…

Ventilation is of primary concern for maintaining healthy indoor air quality and reducing the spread of airborne infectious disease, including COVID-19. In addition to building-level guidelines, increased attention is being placed on room-level ventilation. However, for many universities and schools, ventilation data on a room-byroom basis are not available for classrooms and other key…

The Picarro G2509 gas concentration analyzer is designed for use in livestock farming, manure processing, and fertilizer studies. In these challenging environments, high ambient methane concentrations and rapidly evolving ammonia dynamics can make it difficult to get precise measurements of ammonia and greenhouse gases. The G2509 provides real-time, at-scale measurements of nitrous…

Mr. Gallo is the CEO of Italgas, the leading gas distributor in Italy and the third biggest in Europe. Italgas, headquartered in Milan, Italy,…

Coastal wetlands play an important role in nitrogen removal and are a vital blue carbon sink. The produced methane (CH₄) in coastal wetlands has been recently identified as a possible carbon source for denitrification process, providing a significant contribution to coastal nitrogen cycling. However, the in-situ correlation between CH₄ emissions and denitrification…

It’s now common knowledge that the atmospheric carbon dioxide concentration is increasing steadily due to the burning of fossil fuels, and that the increase in emissions of greenhouse gases (GHGs) like carbon dioxide is causing climate change and triggering substantial changes in our ecosystems. One effect of increasing carbon dioxide concentrations is a higher photosynthetic activity that…

Picarro uses the same type of KNF pump in some of our systems but they might be in different housing:
* Inside a CPVU of a G1000 series analyzer
* G2000 pump (p/n S2000 or A2000)
* Vaporizer pump (p/n S1100)

This video shows one for the S2000 pump housing but the diaphragm replacement part is applicable for all pumps above.
