Abstract: A gas chromatographic device comprises an inlet system and a chromatography column. The inlet system includes a liner having pressure reducing means contained therein for reducing pressure between an inlet of the pressure reducing means and an outlet of the pressure reducing means. When the devise is in use, the chromatography column is positioned in the liner of the inlet system downstream from the pressure reducing means, and the chromatography column is under vacuum at its outlet.

Abstract: A plastic device, such as a syringe barrel, tube, cartridge, filter disk, tubing, solvent reservoir, connector, valve, frit, or container, for transferring or storing solids and liquids used in sample preparation and extraction (SPE) methods, is provided with a barrier coating layer of Parylene over the surface of the plastic device, to prevent contamination of the solids and liquids being transferred or stored by the inventive plastic device from contaminants introduced from the plastic of the device.

Abstract: A device for erotically stimulating the male sexual organ and for obtaining an erection by males with Erectile Dysfunction Disorder includes a soft plastic cylindrical container having an open end which forms a cavity for receiving the male sexual organ. The device further includes unattached free-moving membrane-like material within which tap water is sealed inside and said material thus inserted, entirely within the said container. The device is the only device in the medical and sexual aid fields that can easily be assembled at home and provides simultaneous sucking action and realistic-like membranous tactile sensation to the male sexual organ replicating the female vagina.
