Designed for detecting VOCs over the widest dynamic range on the market without compromising performance, the MiniPID sensor range is designed for both diffuse and in-line pumped sampling. It can deliver a reliable response to thousands of VOCs across many applications. ...
These spectrometers are ready for field or laboratory use, with options for fiber optic probes, large area diffuse reflectance sampling for inhomogeneous solids, and temperature-controlled transmission measurements. ...
The AQ1 and AQ2 discrete analyzers will also be on display offering users minimal operator involvement and the ability to run many different chemistry tests from each sample in the same run. For those laboratories that require high throughput, accurate analysis with very low detection limits for very large numbers of samples, there will be an opportunity to see ...
We will be exhibiting our full range of diffusion tubes for monitoring of VOCs, NO2, NOx, O3, SO2, Acid gases, H2S, Ammonia and Formaldehyde. Diffusion tubes are an excellent, low-cost sampling method allowing pollution over wide areas to be efficiently monitored for a long time period – each exposure period is usually 2-4 weeks. ...
If warranted by the results of the sampling data, EPA may undertake additional sampling and/or mitigate exposure to contaminants through indoor air utilizing its emergency response authority. EPA will conduct groundwater sampling and analysis of samples from the existing well network during the week of October 24th. ...
Rock core contaminant analyses at this site, and at many other sedimentary rock sites where more advanced versions of the method have been applied, shows that at aged sites, nearly all of the contaminant mass now resides as dissolved and sorbed phase in the low permeability matrix blocks between fractures due to diffusion. Noteworthy is the fact that groundwater ...
The traditional measurement methods were developed for repacked sieved soil and are not well-suited for measuring intact soil samples, since they require prior knowledge of the magnitude of diffusivity of the individual soil sample – something which is often not available for intact soil due to its heterogeneous nature. ...
