Flow-induced errors in airborne in situ measurements of aerosols and clouds
Abstract. Aerosols and clouds affect atmospheric radiative processes and climate in many complex ways and still pose the largest uncertainty in current estimates of the Earth’s changing energy budget. Airborne in situ sensors such as the Cloud, Aerosol, and Precipitation Spectrometer (CAPS) or other optical spectrometers and optical array probes provide detailed information about the ...

Monitoring Considerations for Critical Environment Cleanrooms
Facilities grappling with USP797 and USP800 verify their compliance through cleanroom certification. Airflow measurements, leakage testing and environment measurements (differential pressure, temperate and relative humidity) are documented and certified. Non-cGMP certified facilities, do not generally have ongoing monitoring of their cleanroom space and have difficulties identifying when ...

Prosperity Years 1951-1953 - Part 4 Teledyne Hastings History
The early part of the 1950’s was prosperous for Hastings due in part to the demand for the Raydist and large military contracts as a result of the Korean War. Sales nearly tripled between 1950 and 1953 and there were almost 200 employees. Hastings had outgrown its space yet again and expanded to a 14,000 square foot building on Newcomb Avenue (current day location for Teledyne Hastings). ...

Ventilation Measurements Using Sulfur Hexafluoride (SF6) Tracer Gas
Sulfur Hexafluoride, also known as SF6, is by far the most common tracer gas used for ventilation studies. The primary reason is that it is easy to detect at very low concentrations—even in the parts per billion (ppb) or parts per trillion (ppt) range and has a very low toxicity. The best instrument to detect SF6 is an infrared spectrophotometer. Although the portable units are still a bit ...

What`s the Best Air Pollution Control Technology for My Process?
Air pollution control equipment is not something that business owners address by saying, “Let’s do the right thing for the environment and install an oxidizer!” In fact, the scenario is more likely to be “We need to increase productivity (always a good thing!), but that will put us over our annual emissions limits. Do we know what we will need? Where do we start? Who can ...

Influence of relative air/water flow velocity on oxygen mass transfer in gravity sewers
Problems related to hydrogen sulfide may be serious for both network stakeholders and the public in terms of health, sustainability of the sewer structure and urban comfort. H2S emission models are generally theoretical and simplified in terms of environmental conditions. Although air transport characteristics in sewers must play a role in the fate of hydrogen sulfide, only a limited number ...
