  • Analyzing sulfur in soil and sediment with handheld XRF

    Background Sulfur creates more than nasty odors. Exposure to low levels (0-10ppm) of hydrogen sulfide (H2S) causes irritation of eyes, nose, and throat; higher levels can cause headaches, dizziness, nausea and vomiting, coughing, and breathing difficulty. H2S and numerous other odor-causing compounds are generated as a result of organic material decomposition. In the case of the Muddy River in ...

  • 5 Reasons to Perform a Consequence Modeling Analysis for Your Facility

    The potential for accidental release of toxic chemicals to the environment is a daily threat for many industrial facilities and plants. These releases can occur very suddenly and unexpectedly, putting employees and the public at risk of injury or death, and the surrounding environment at risk of damage or destruction. A consequence modeling analysis is a powerful tool (and sometimes a regulatory ...

  • Analysis of Natural Gas Products by GC / TCD / FID

    The complex mixture of condensible hydrocarbons and permanent gases in a natural gas product has historically been separated on gas chromatographs equipped with dual columns and a switching valve. The light gases are separated from heavier compounds on a molecular sieve column, which is then backflushed onto a suitable column to separating the rest of the mixture. The Buck Scientific Model 910 ...

  • Performance of solid-state sensors for continuous, real-time measurement of soil CO2 concentrations

    Recent advances in sensor technology provide a robust capability for continuous measurement of soil gases. The performance of solid-state CO2 sensors (Model GMM220 series, Vaisala, Inc., Helsinki, Finland) was evaluated in laboratory, greenhouse, and irrigated winter wheat (Triticum aestivum L.). In ambient CO2 concentration, the GMM222 sensor averaged 427 ± 8.3 µL L–1. Under variable CO2 ...
