    摘要: The flushing of the syringe with a side port is performed by introducing a liquid solvent through the side port while the plunger is retracted from the barrel. At the completion of the flushing operation the plunger is fully inserted into the barrel expelling all the solvent except that in the needle. The needle is then inserted into the sample and the plunger is raised to withdraw the sample. With this arrangement, it is possible to take a 0.1 L sample and dispense it because of the solvent reserve in the barrel. Furthermore, the solvent reserved in the barrel provides a buffer so that sampled material does not contact the plunger or get into the annular space around the retracted plunger.

    摘要: An electrostatic chuck is provided with an electrode split into two sections. The separate sections are joined through a tapered joint and bonded using epoxy. An insulator electrically separates the two sections and covers the top of the joined sections to form a clamping surface. The geometry of the electrode forms three annular regions, dividing the clamping surface into two equal areas distributed symmetrically. Moreover, the split-ring electrostatic chuck just described is fabricated by forming the two, separate electrodes; coating the separate electrodes with an insulator; joining the electrodes; machining the joint, top surface of the electrodes to form a single, co-planar, flat, smooth surface; and applying an insulator to that top surface.
