20140291170 | ETHYLENE GAS DETECTION DEVICE AND METHODS OF USE - Provided herein are methods, apparatuses, and systems for enhancing the detection of reactive gases, such as ethylene gas, that are present at low concentrations in air samples. The methods and systems enhance the selectivity, sensitivity, and accuracy of electrochemical cells by removing interfering gases from the air samples. Some systems include an ethylene sensor that includes an electrochemical cell and a polar solvent gas trap pre-filter, wherein the gas trap is positioned upstream of the electrochemical cell. Some methods are methods of measuring an ethylene level in an air sample, and include passing the air sample by through a polar solvent gas trap, and measuring the ethylene level in the air sample with an electrochemical cell. | 10-02-2014 |
