A device for transporting and focusing ions in a low vacuum or atmospheric-pressure region of a mass spectrometer is constructed from a plurality of longitudinally spaced apart electrodes to which oscillatory (e.g., radio-frequency) voltages are applied. In order to create a tapered field that focuses ions to a narrow beam near the device exit, the inter-electrode spacing or the oscillatory voltage amplitude is increased in the direction of ion travel.

An assembly design for an oscillating resonator-based sensor where an oscillating crystal resonator such as a quartz crystal resonator is rigidly affixed or ‘mounted’ onto a solid substrate in such a fashion that the resonator can either rest flush against the substrate surface or upon a rigid mounting adhesive. Once cured, the mounting adhesive forms a liquid tight seal between the mounted resonator and the substrate such that only the sensing electrode surface will be exposed to fluids applied to the front side of the substrate. The mounted resonator assembly is designed in such a way that it can be interfaced with a fluid delivery system to form a liquid tight chamber or flow cell around the mounted resonator without incurring additional physical impact upon the mounted resonator. The assembled flow cell can in turn be used to direct multiple fluid streams to flow in a laminar manner over the sensing surface of the mounted resonator and by varying the rates of flow for the different laminar flowing fluid streams the total hydraulic pressure exerted on the surface of the mounted resonator can be held constant.

A composition comprising alkyl esters, with a C1-C8 alkyl group, and partial glycerides, with a free glycerol content of, at most, 2%, by weight, based on the weight of the composition, derived in an enzymatically-catalyzed reaction from saturated or unsaturated, straight or branched C8-C22 fatty acids of vegetable oils, and useful, inter alia, in biofuels, such as biodiesel, and as an additive for improving the lubricating performance of fuel compositions.
