摘要： A combination of a membrane, such as a silicone rubber membrane, and a valve having a chamber within it, such as a solenoid valve. The present invention is suitable, for example, for use with a mass spectrometer. The membrane partitions the chamber into a first chamber portion and a second chamber portion. The valve has at least three passageways into it. The first two passageways lead to the first chamber portion. The third passageway leads to the second chamber portion. A solenoid plunger is used to close off the third passageway when desired. When used with a mass spectrometer, the third passageway is connected to the vacuum inlet of the mass spectrometer and a sample is flowed into and out of the first chamber portion via the first two passaageways. A component of interest in the sample can permeate across the membrane into the second chamber portion and can flow via the third passageway to the mass spectrometer. When desired, the plunger can be used to close the third passageway.

摘要： A device for introducing a sample into a mass spectrometer which generally comprises a probe which is connected to the mass spectrometer and a semipermeable capillary tube connected at the end of the probe. The probe includes conduit passageways for permitting bidirectional fluid flow through the probe, and the capillary tube is connected to the end of the probe so as to permit the flow of a fluid containing the sample to be analyzed through the probe and the capillary tube. This fluid flow through the capillary tube will enable at least a portion of the sample to be transferred into the mass spectrometer via diffusion through the capillary tube.

摘要： The present invention is a laminate which comprises: a) a plastic substrate having a surface; b) an adhesion promoter layer which is a first plasma polymerized organosilicon compound deposited on the surface of the substrate in the substantial absence of oxygen; and c) a protective coating layer which is a second plasma polymerized organosilicon compound deposited on the surface of the adhesion layer at a power density from about 10.sup.6 J/kg to about 10.sup.8 J/kg, and in the presence of a sufficient stoichiometric excess of oxygen to form a silicon polymer of SiO.sub.1.8-2.4 C.sub.0.3-1.0 and H.sub.0.7-4.0. The coating layer provides abrasion and solvent resistance for the substrate, and the adhesion promoter prevents the coating layer from peeling off the substrate. The coated plastic substrate can be used in liquid crystal display devices as an alternative to glass.

摘要： A system for measuring the permeation rate of organic molecules across a polymer film, which includes a membrane chamber, an electron impact mass spectrometer and a flow-through hollow fiber probe for providing an interface between the membrane chamber and the mass spectrometer. The membrane chamber supports the polymer film sample to be tested, and permits one side of the sample to be exposed to a vapor containing a known concentration of organic molecules under substantially atmospheric pressure and controlled environmental conditions on both the upstream and downstream sides of the sample. The membrane chamber features a unique permeation cell and sample holder arrangement which employs a pair of adhesive backed cards to sandwich the sample and maintain a permanent desirable alignment of the sample.

摘要： This invention relates to several improvements in mass spectrometric analysis. In accordance with one aspect of this invention, a mass spectrometer sampling system is provided in which a continuous flowing liquid stream can be sampled into a carrier gas stream where it is heated and vaporized. The gas and vapor mixture is transmitted into a plurality of chambers connected in series which have the effects of diluting the concentration of the vaporized liquid injected into the inert gas streams and also shaping the concentration time profile at the exit of the last chamber to be a symmetric peak. These effects have been found to provide several advantages such as prolonging the instrument operation time, and allowing a faster sample injection rate. Once the mixture has exited the last of the chambers, a molecular leak is provided to reduce the pressure to that necessary for the operation of the mass spectrometer. A series of chambers in accordance with this invention has also been found to enable very thorough mixing of reagents.
