摘要： A method and apparatus for determining a volatility of a fuel sample. A fuel sample is collected in a container and heated for a time period using a heater device. Periodically during the heating, the capacitance of the fuel sample and the temperature of the heater device are determined. After a time period passes, the volatility of the fuel sample is determined using the capacitance decrease and the temperature increase. Specifically, a voltage across the heater device is used, along with the current through the heater device to determine the resistance of the heater device, which gives the temperature of the heater device and the sample. The capacitance and temperature are compared to values derived from experimentation for fuels of varying DI. The first measurement of capacitance with a known sample volume can be used to determine the MTBE or ethanol content in gasoline fuels.

摘要： The present invention includes a microelectrode which achieves a surface-renewal advantage. The sensor and method directly controls the oxidizing and reducing nature of the electrode interface by controlling the cell potential, thereby protecting the sensing electrode's surface during periods in which the sensor is not being used. The microelectrode is biased at a small positive potential relative to the counterelectrode, except when a measurement is desired. To measure oxygen concentrations in brake fluid, the microelectrode is biased at a greater potential and the current is measured. After the current measurement, the potential is returned to the small positive potential. The oxygen concentration (and thus the amount of air) in the brake fluid is linearly related to the current measured.
