The present invention provides a device and process that rapidly assesses volatile organic compounds (VOCs) present in a gaseous state by reading gas emitted through a subject's skin into the ambient surroundings. The device delivers rapid high-sensitivity capture, classification and pattern recognition to identify a unique VOC profile derived from that bio-sample. A flexible probe module can be appropriately configured with attachments to collect gases from the air surrounding any person, any area enclosed or proximal to a potential VOC source, and/or in clinical applications, near any skin surface, from zones or areas within or immediate adjacent to a body orifice such as nasal passage, otic canal, mouth, armpit, vagina, urethra, navel, anus, vagina, scalp, torso, palm, foot, etc. The device thus provides a practical screening device for clearing persons of interest, e.g., in a waiting room, planning to enter a room or building, a client seeking a personal meeting, etc., and/or providing a handyman, health care worker, or other service provider, a means of assurance when entering a place of service.

A gas-liquid separator, adapted for separating liquid and gas in an ebullated bed reactor under operating conditions, is disclosed. The device may be used in the petroleum and chemical processing industries in catalytic reactions of hydrocarbonaceous feedstocks in the presence of hydrogen, at an elevated temperature and pressure, to separate gas and liquid from gas and liquid mixtures within the reactor. The device is generally vertically oriented and may be installed in the flow through pan of an ebullated bed reactor. The device comprises a transfer conduit for transferring a gas-liquid mixture stream from a lower section of an ebullated bed reactor to an upper section of the reactor, a vortex separation section having gas-rich and liquid-rich stream outlets, and a gas-rich stream outlet conduit located on top of and adjacent to the vortex separation section. The transfer conduit includes internal means to produce a spiral flow in the gas-liquid mixture, such as a helical or spiral insert. The vortex separation section is located at the top of the transfer conduit and includes separation means to separate the gas-liquid mixture stream into a liquid-rich stream and a gas-rich stream. A separator conduit extending from the top of the vortex separation section to the transfer conduit upper opening, aligned with and having substantially the same cross-sectional dimensions as the gas-rich stream outlet, may be used as the separation means. Among the benefits provided are improved efficiency of gas and liquid separation and reduced gas holdup within the reactor.

A measuring apparatus and a method for determining the degree of bacterial contamination of process liquids uses at least one gas sensor for measuring the gas concentration of a gas producible by aerobic bacteria in the process liquid. An evaluating device is connected with the sensor for evaluating a sensor signal generated by the sensor and correlated with the degree of bacterial contamination. To determine the degree of bacterial contamination a funnel-shaped gas collecting bell is partly immersed in the process liquid so that a gas collection cavity for collection of the escaping gas is formed directly above the process liquid surface in the gas collecting bell. The gas escaping can be fed by a gas pump via a gas feed line to the sensor, conducted via the sensor and pumped back again to the gas collection cavity by way of a gas return line.

The purpose of the present invention is to provide an injection apparatus and an injection method for a liquid sample for standard gas production, wherein the injection apparatus for injecting a liquid sample present in a liquid state at room temperature into a standard gas container has an improved structure that minimizes the area in which the liquid sample directly contacts the injection apparatus so as to prevent the problem in which the liquid sample is adsorbed into the injection apparatus. Furthermore, another purpose of the present invention is to provide an injection apparatus and an injection method for a liquid sample for standard gas production, in which a step of volatilizing the remaining liquid sample by heating is eliminated during the injection of the liquid sample, thereby preventing the apparatus from being damaged by heating to thereby improve the durability of the apparatus.

The present document describes a process for production of hydrogen gas (H.sub.2) from fermentation of crude glycerol with a hydrogen producing microorganism in a bioreactor. The process comprises the step of introducing a volume of crude glycerol in a fermentation mixture which comprises a fermentation medium comprised of crude glycerol and hydrogen producing microorganisms under a fermentative hydrogen production condition, and then removing a volume of the fermentation mixture equal to the second volume of the crude glycerol, to maintain constant the total volume of the fermentation mixture.
