Abstract: A system for analysis of at least one analyte gas present in an insulating fluid of an electrical transformer includes a gas sensor in operational contact with at least one analyte gas from an insulating fluid to provide multiple responses from the sensor. One or more processors are configured to receive the multiple responses during exposure of the sensor to the analyte gas from the insulating fluid representative of a concentration of the analyte gas present in the insulating fluid. The processors are configured to select one or more responses of the multiple responses that provide rejection of interfering gases, resolution between gases, improved low detection range of the analyte gas, improved high detection range of the analyte gas, improved response linearity of the analyte gas, improved dynamic range of measurements of the analyte gas, or one or more combinations thereof compared to non-selected responses from the sensor.

Abstract: A sensing system includes a sensor and one or more processors. The sensor includes a sensing region in contact with an industrial fluid. The sensing region includes electrodes and a sensing region circuit electrically connected to the electrodes. The sensing region circuit generates an electrical stimulus having multiple different frequencies that are applied to the industrial fluid via the electrodes. The one or more processors receive one or more electrical signals from the sensor representative of an impedance response of the sensing region to the electrical stimulus. The one or more processors analyze the impedance response and determine at least one of a contaminant concentration of an external contaminant in the industrial fluid, an acid concentration of acidic components in the industrial fluid, or a base concentration of basic components in the industrial fluid based on the impedance response.

Abstract: Methods for selecting a binding-element are provided. The method comprised of different steps. A first mixture is formed using at least one target molecule and a plurality of oligomers, followed by incubating the first mixture to form a second mixture comprising at least one target-bound oligomer and at least one target-unbound oligomer. Then a first accelerator is added to cleave the target-unbound oligomer and the target-bound oligomer is separated from the target molecule. This is followed by addition of a second accelerator for ligation, and a third accelerator for amplification followed by sequencing and post sequence analysis to select the binding-element.
