  • Patent number: 11293912
    Abstract: A method for measuring TOC in test water is disclosed. Test water is injected into a combustion tube, which is controlled to be heated in a state of flowing carrier air generated by discharging stored water filled in a combustion gas or carrier air storage tank. After the drying process, temperature in the combustion tube is increased, and the dried organic carbon is burned. Combustion gas is guided to the combustion gas storage tank. An inside of the combustion tube is purified due to high pressure steam generated by injecting pure water and organic carbon removed in the purification process is burned and oxidized. The generated combustion gas is guided to the combustion gas storage tank and is pushed into an infrared meter to measure a carbon dioxide gas concentration. Otherwise, the generated combustion gas is guided to the infrared meter to measure the carbon dioxide gas concentration.

  • Patent number: 11221318
    Abstract: Provided is a system for detection and discrimination of gases, such as volatile organic compounds (VOCs), in a sample comprising two chambers, a first chamber equipped with a crystalline microporous material (CMM) and a second chamber equipped with a gas detector. A gas sample is introduced first into the second chamber for detection by the gas detector and is then re-routed to the first chamber for adsorption/desorption on the CMM. The gas detector in the second chamber produces electronic signals that correspond to the adsorption/desorption profile for the gas, which allows for discrimination of the gas in the sample from other possible gas samples.
