  • Patent number: 10823649
    Abstract: A microfluidic device includes a sample inlet for a fluid sample, a degassing chamber having a gas-permeable membrane and defining first and second portions separated by the gas permeable membrane, and a detection chamber. The sample inlet and the detection chamber are fluidly coupled to the first and second portions, respectively of the degassing chamber. The detection chamber is operably coupled to a light source and a detector. Assessing a concentration of chlorine gas in an aqueous sample includes providing an aqueous sample to a microfluidic device, separating gas from the aqueous sample in the microfluidic device, providing the gas to a detector, assessing the absorbance of the gas sample at a known absorption wavelength of chlorine, and based on the assessed absorbance of the gas sample at the known absorption wavelength of chlorine, assessing a concentration of chlorine gas in the aqueous sample.

  • Publication number: 20140008303
    Abstract: An absorption device for use with a waterless urinal comprises an exchange container containing at least one ion exchange resin. The exchange container comprises a housing and at least one resin support. The ion exchange resin can be a cation exchange resin that removes calcium and magnesium ions from urine. The ion exchange resin can be an anion exchange resin that removes anionic pharmaceuticals from urine. The ion exchange resin can be a hybrid anion exchange resin that removes phosphorous comprising anions from urine. The absorption device permits the removal of cations that result in scale and blockage of waterless urinal drain pipes and removes ions that otherwise would require treatment at wastewater treatment facilities.
