  • Method and device for calibrating a fluid detector having a preconcentrator
    Patent number: 11927514
    Abstract: A method is provided for calibrating a measurement process for a measurement system having a fluid detector, which is provided with a preconcentrator and a fluid sensor. The measurement system for detecting a concentration of a substance to be detected has a sorption phase, during which the fluid to be detected is enriched for a sorption duration (t) in the preconcentrator in a first state, and a measurement phase, in which a concentration of the substance to be detected resulting from the release of the substance to be detected that was enriched in the preconcentrator is measured. The fluid detector is calibrated by adjusting the sorption duration (t).

  • Cells having cavities and the manufacture and use of the same
    Patent number: 9498777
    Abstract: Cells having cavities and the manufacture and use of the same are described. An example cell includes a first layer including a gap to at least partially define a cavity and a reservoir area to receive material to enter the cavity by diffusion. Additionally, the cell includes one or more other layers coupled to the first layer to at least partially define the cavity and to hermetically seal the cavity from an exterior environment.

  • Gasoline additives
    Patent number: 7901470
    Abstract: The use of an effective concentration of a hydrocarbyl amine wherein the hydrocarbyl moiety has a number average molecular weight in the range 140 to 255 as an additive in an unleaded gasoline composition is provided containing a major proportion of a gasoline suitable for use in a spark ignition engine, for reducing injector nozzle fouling in a direct injection spark ignition engine. A method of operating a direct injection spark ignition engine is also provided.
