  • Patent number: 6620331
    Abstract: The invention relates to a method for etching an opening, and more precisely, to etching in a silicon plate for creating a nozzle opening. According to the invention, one side of the silicon plate (1) is protected by a protective layer (2), and a recess (5) is made in the protective layer. Etching is made anisotropically through the recess so as to create a cavity (4) in the shape of a truncated pyramid of a predetermined depth in the silicon plate. The cavity is doped so as to create a doped layer (3) at the predetermined depth. The etching is then continued until the bottom surface of the cavity has passed the doped layer. Subsequently, etching is performed from the other side, while a voltage is applied to the doped layer, so as to free the nozzle opening at the other side. The invention enables an accurate control of the surface area of the nozzle opening. Through this, the amount of discharged fluid and the directional precision can be controlled very accurately.

  • Patent number: 6345540
    Abstract: A fluid flow meter has a semi-conducting substrate and a number of integral flexible tines orientated across an aperture in the substrate to deflect in the direction of the fluid flow by an amount dependent on that fluid flow. Piezo-resistive regions are included on the respective tines to provide them with electrical characteristics which vary dependent on the degree of deflection. A monitor, operably coupled to the regions of the tines, is provided to monitor the changes in their electrical characteristics and to calculate the flow therefrom.

  • Patent number: 6192768
    Abstract: A sampling cell of flow-through type and use of such a sampling cell. The sampling cell is preferably manufactured by etching of silicon wafers. It is especially useful for continuous picovolume sampling in an analytical flow. The pressure pulse generator (9) generates pulses directly into a flow channel (3). The flow channel (3) is preferably formed by a first basin (4) in a first structure (1) and a second basin (5) in a second structure (2). In a first embodiment the pressure pulse generator (9) comprises at least one piezo-ceramic disc and/or devices acting by way of magnetostrictive, electrostatical or electromechanical forces and/or devices acting by way of thermal expansion. Method of directing samples from a flow-through sampling cell by establishing a difference in electrical potential between the liquid in the flow-through sampling cell and the object to which the samples are to be directed.
