  • Patent number: 10302605
    Abstract: A column assembly for gas chromatography, which is coolable by a fluid, includes a capillary column, a heating element for heating at least a portion of the capillary column, and a tube having a lumen and in contact with at least one of the capillary column and the heating element. When energized, the heating element raises the temperature of the capillary column. To lower the temperature of the capillary column, a fluid flows through the tube, and heat is transferred from the capillary column to the fluid in the tube.

  • Patent number: 6682699
    Abstract: This invention provides a reduced power consumption gas chromatograph system (10) which includes a capillary gas chromatograph column member (12) which contains a chemical sample to be analyzed. The gas chromatograph system further includes a heating mechanism (16) which extends throughout the length of the capillary gas chromatograph column member (12) and surrounds both the member (12) and a temperature sensing mechanism (14) which is mounted adjacent to the column member (12). The temperature sensing mechanism (14), the heating mechanism (16) and the column member (12) form a chromatograph column assembly (20) which includes a coiled section (28) where the components are tightly packed with respect to each other and allows for a reduced power consumption for temperature programming miniature gas chromatography column assemblies.

  • Patent number: 6530260
    Abstract: A gas chromatography system includes a gas chromatography oven having a door adapted for integration with gas chromatography modules which are located outside of the oven cavity. For these purposes, the oven door has module receiving openings in which the modules are secured. The gas chromatography module includes a module housing containing a main coil of the capillary column, a pair of transfer lines sleeved on the free ends of the capillary column, a heater wire wound on the transfer lines, and, optionally, a pair of chromatography connectors which extend into the oven cavity and through which the free ends of the capillary column, as well as transfer lines, projecting into the oven cavity. A wall of the GC oven has an injector port and a detector port for injection of a sample into the oven cavity and for detecting the sample constituents. Column lengths extend within the oven cavity between the module and injector and detector, respectively.

  • Patent number: 6223584
    Abstract: A system for analysis of vapor constituents in a gaseous and/or liquid media includes an analyzing gas chromatographic unit, an in-line preconcentrator assembly having a trap housing, an adsorbent material received in the trap housing, and a transfer line unit couplable to the trap housing and directly connected to the analyzing unit. Carrier mechanism drives the trap housing with respect to the transfer line unit linearly or along an arc trajectory. When the trap housing is displaced from the transfer line unit, the media surrounding the trap housing is forced inside of the trap housing by a pump and vapor constituents are adsorbed on the adsorbent material within the trap housing. When the trap housing is moved in pressure tight engagement with the transfer line unit, the adsorbent material is heated to release the vapor constituents from the adsorbent material.

  • Patent number: 5932397
    Abstract: Multicolor lithography is described in which the wavelength-dependent variation of light penetration into a photosensitive polymer is used to provide three-dimensional control of the refractive index gradients in the polymer resulting from photo-induced changes in the polymer. This invention provides the first method for three-dimensional index control compared to previous waveguide fabrication technologies which provide primarily two-dimensional control with very limited or no process variation in the third (depth) dimension. This method makes possible the simultaneous fabrication of multiple sizes of single mode buried channel waveguides in a single fabrication with low loss waveguide tapers connecting these channel waveguides. This approach provides large waveguides for efficient coupling to fibers while at the same time providing low loss waveguide taper transitions to small single mode waveguides.

  • Patent number: 4479795
    Abstract: The present invention relates to medical polymers and devices made therefrom, and is based on the discovery that certain carboxylate antimicrobial agents can be releasably incorporated into permeable polymers. The walls of medical devices such as catheters can be fashioned from such polymers. In use, the antimicrobial agent diffuses from the walls to the surface of the device to form an antimicrobial barrier on the surface of the device and a zone of microbial inhibition on tissue surfaces surrounding the device, thereby effectively supplementing the body's own natural microbial barriers where they have been compromised. The bacterial contamination-resistant carboxylate-plus-polymer compositions herein can be used in the manufacture of a wide variety of medical devices, especially urinary catheters, intravenous catheters, wound dressings, and the like.

  • Patent number: 4410442
    Abstract: Disinfecting solutions for use with hydrophilic soft contact lenses, containing effective amounts of C.sub.5 -C.sub.12 fatty acids, especially octanoic acid, are disclosed. These solutions provide broad spectrum antimicrobial efficacy together with rapid and complete desorption of the fatty acid antimicrobial from the contact lens material, resulting in a minimization of irritation and sensitization risks to the user. The method of disinfecting hydrophilic soft contact lenses using C.sub.5 -C.sub.12 fatty acids is also disclosed.
