摘要:
Methods and assemblies for ion detection in samples using a chip with elevated sample zones, also known as a “pillar chip.” Methods include analyzing such a sample by desorbing a sample from a chip, producing a described ion sample and detecting the same. The chip comprises a base having a surface and one or more structures protruding above the surface of the base. Each structure comprises a pillar and a sample zone, the latter containing a support material and the sample to be analyzed. Assemblies include a chip such as that described above and a conductive element that comprises an aperture of sufficient proportion to allow passage of a molecular ion and that is adapted to be at a different electrical potential than the base of the chip.
摘要:
Method for manufacturing a machine housing having a fluid chamber (14) with a hardening layer (16) on an internal wall surface, in which the hardening layer (16) is made of a material, that, per-se, is not electrically conductive but has been made conductive by additives, and in that the surface of the hardening layer (16) is machined by electro-discharge machining.
摘要:
An apparatus for opening and depositing a signature onto a transporting device includes a continuously rotating gripper cylinder having a first shaft and carrying at least one signature. First and second opening cylinders are arranged below the gripper cylinder to open the signature and deposit the opened signature onto the transporting device. The first and second opening cylinders each have a second and third shafts, respectively, extending substantially parallel to the first shaft. The first and second opening cylinders each have a peripheral section, the peripheral section of the first opening cylinder engaging in a region of rotation of the gripper cylinder to grip a signature such that the signature can be released again. The first opening cylinder includes a guide element to aid in conveying the signature.
摘要:
Methods, devices and arrays for measuring a change in zeta-potential of a surface indicative of a binding event are provided. Pharmacologically active compounds and delivery systems for active pharmaceutical ingredients determined to be pharmacologically active or optimized for pharmacological activity or determined to be useful for delivery of the active pharmaceutical ingredient to a target via measurement of a change in zeta-potential of the compound, ingredient or delivery system are also provided.
摘要:
A system for storing and rendering multimedia data includes a first storage configured to store multimedia data files of a plurality of formats. The system also includes a second storage configured to store program files including information regarding a transformation of multimedia data files of a first format into multimedia data files of a second format, where the first format is one of the plurality of formats. The system also includes a rendering device configured to render multimedia data files of the second format. At least one of the multimedia data files stored in the first storage is linked to at least one of the program files, and the program file includes information regarding a transformation of multimedia data files of the format of the at least one of the multimedia data files into the second format.
摘要:
A method and kit for assaying a cell sample for the presence of at least a threshold number of cells of a given type are disclosed. The kit includes an assay device having a sample chamber for receiving the cell sample and an elongate collection chamber containing a selected-density and/or viscosity medium and having along its length, a plurality of cell-collection regions, and particles which are capable of specific attachment to cells of the selected cell type, and which are effective, when attached to the cells, to increase the density or magnetic susceptibility of the cells. In operation, particle-bound cells and particles in the cell sample are drawn through the elongate collection chamber under the influence of a gravitational or selected centrifugal or magnetic-field force until the particle-bound cells and particles completely fill successive cell-collection regions in the collection chamber. Indicia associated with at least one collection regions indicates a concentration of cells of the selected type effective to at least partially fill that collection region.
摘要:
A pump having an axial impeller (40) with helical blades (38) for sucking liquid through an intake opening (38) formed at a bottom side of the axial impeller (40), in which the blades (38) are provided, at the bottom side of the axial impeller (40), with a first cutting edge (58) which, when the axial impeller (40) rotates, are in cutting relation with at least one second cutting edge (60) formed at the intake opening (36).
