A second effluent, from the secondary separation module, includes temporally-resolved organic component and analyte peaks due to selective retention of the analyte. The second effluent is provided to a flame-based detector which is disabled when the organic modifier peak is received and enabled at least during the time when the analyte peak is received.

The method includes separating dissolved inorganic halides and dissolved organic halides in water using an electrodialysis technique (S1), which may completely separate the dissolved organic halides and the dissolved inorganic halides, avoid the use of activated carbon and adsorption columns, simplify steps and improve efficiency. The method converts the separated dissolved organic halides into dissolved inorganic halides using a photocatalysis technique (S2), which does not need a special high-temperature combustion device, active carbon and catalysts, and is simple and easy to be performed at room temperature in more environmentally friendly mode.

  • Publication number: 20190094193
    Abstract: Embodiments relate generally to systems and methods for determining the location of a gas detector device, wherein the location may be within a predefined location zone, and automatically configuring the gas detector device based on the location zone. Each location zone in a facility may be associated with a configuration for the gas detector device. The location of the gas detector device may be monitored by a central station, and when it is determined that a gas detector device has moved from one location zone to another, the configuration of the gas detector device may be updated accordingly. Additionally, other parameters may be monitored by the central station and/or the gas detector device to determine the appropriate configuration of the gas detector device.

    Abstract: Contaminant cleaning systems and related methods are provided. Exemplary embodiments include a reactive substance generator to produce or transfer reactive substance(s) that react with contaminant(s) on an item into a cleaning chamber. An analysis section can be attached to the cleaning chamber to perform gas analysis on gas samples brought into the analysis chamber that measure reaction byproducts from the reactive substance(s) interaction with the contaminants. An exemplary valve system can selectively couple the reactive substance generator, the analysis section, and the cleaning chamber. An exemplary pumping system, in combination with the valve system, can selectively generate differential pressure/vacuum levels between the reactive substance generator vs cleaning chamber as well as between the cleaning chamber and analysis section. For example, the analysis chamber can be configured to have a higher vacuum than the cleaning chamber to facilitate passage of gas test samples into the analysis chamber.

Embodiments can identify the existence of one or more anomalies in the uniformity of concrete and/or grout, and/or determine or estimate the size, shape, type, and/or location of one or more anomalies in the uniformity of concrete and/or grout. Embodiments can utilize a string of temperature measuring sensors placed within one or more access bore(s), such as tube(s), positioned at least partially within the concrete and/or positioned proximate the concrete. The measurements obtained from the temperature measuring sensors can then be used to assist in the identification of existence of, size of, type of, shape of, and/or location of anomalies in the concrete and/or grout.
