    摘要: Pressurised aerosol compositions comprise a medicament, a hydrofluorocarbon propellant and a polyethoxylated surfactant, the compositions containing substantially no solvent, other than the propellant, capable of increasing the solubility of the surfactant in the propellant. The compositions according to the invention are advantageous in that the solubility of the surfactant is such as to ensure good dispersion of the medicament and smooth operation of the aerosol valve.

    摘要: A method of preparing functionalized particles including (a) treating an activated substrate (CPG) with a bifunctional cross-linking agent containing a cleavable bond so as to immobilize the cross-linking agent, (b) conjugating an activated particle (P) with the immobilized cross-linking agent, and (c) cleaving the cleavable bond so as to separate the particle (P) from the substrate (CPG). The functionalized particles subsequently can be conjugated to biologically active molecules for use in assay methods.

    摘要: The invention provides apparatus and methods for investigating a small selected area of the surface of a specimen. The specimen is irradiated by a primary beam of X-rays or electrons to cause it to emit electrons. These are collected by a novel electron-optical arrangement and are used to create an image of the selected area of the surface using only those electrons emitted with energies lying in a specified range. Apparatus according to the invention has greater sensitivity and spatial resolution than previously known apparatus.

    摘要: A charged particle analyzer which irradiates a specimen and analyzes charged particles emitted therefrom, for example a photo electron spectrometer, having a flood-source which emits charged particles to neutralize the charge which develops on a specimen. The analyzer is provided with electrostatic and magnetic lenses which may be used separately or in combination. The flood source is provided within the lens column of the analyzer and is arranged such that when the electrostatic lens is in use, the charged particles emitted by the flood source pass around the outside of the objective electrostatic lens element, whereas when the magnetic lens is in use, or when both lenses are in use, they pass through that element.
