    摘要: A modular gas detection system includes a primary gas chromatograph, a constant volume extractor positionable to provide a continuous fluid sample to the primary gas chromatograph, and a total hydrocarbon analyzer. The modular gas detection system also includes a processing device and a memory device including instructions executable by the processing device for causing the processing device to perform operations. The operations include adjusting a detection scheme of the primary gas chromatograph to update a detection range for the continuous fluid sample to detect different hydrocarbons within a single column. Further, the operations include controlling routing of the continuous fluid sample from the constant volume extractor to the primary gas chromatograph and the total hydrocarbon analyzer.

    摘要: A gas analysis device suited for e.g. medical analysis of exhaled breath from a subject. A gas inlet receives a gas sample to a flow path for guiding the gas sample to two or more gas separators, e.g. gas chromatography columns, with respective molecule selectivity properties which are different. One or more detectors, each with a sensor, are arranged to generate respective responses to outputs from the two or more gas separators. A communication module generate output data in response to the respective responses from the one or more detectors, e.g. data indicative of selected molecules in the gas sample, e.g. data indicative of one or more diseases identified as a result of identified biomarkers in the gas sample. The device is suitable as a compact device, e.g. a handheld breath analysis device, since the use of a plurality of gas separators allows use of very molecule specific gas separators which can be implemented with a small size. E.g. a flow path with several parallel paths each comprising one or more gas separator may be used.

    摘要: A method in a separation system including parallel fluid paths each having a separation module, includes providing a sensor of the same type in at least each of the parallel fluid paths except one: measuring a characteristic fluid property with at least one of the sensors in the parallel fluid paths; possibly measuring the same characteristic fluid property with a system sensor positioned in the outlet of the separation system; and comparing measured characteristic fluid properties to evaluate and/or qualify the performance of the separation system.

    摘要: Embodiments of a gas detector with a first gas sensor having a first gas specificity and a first response time and a second gas sensor having a second gas specificity and a second response time. The first gas specificity is different than the second gas specificity, the first response time is different than the second response time, or both the first gas specificity and the first response time are different than the second gas specificity and the second response time. A readout and analysis circuit is coupled to the first and second gas sensors to read and analyze data from the first and second gas sensors, and a control circuit is coupled to the readout and analysis circuit and to the first and second gas sensors to execute logic that operates the first gas sensor, the second gas sensor, or both the first and second gas sensors.

    摘要: A system and method for separating the functions of a liquid chromatography (LC) system into physically separate systems that allow for a more versatile LC system, wherein an LC device provides column 50 a liquid solvent, a sample, and a pump and injector that pushes the sample in the solvent to an output port, and providing an attachable module containing a module input port, a column, a heater for the column, and at least one detector for on-column detection, then attaching the module to the LC device using a press-fit connection that enables the sample in the solvent to be pumped through the column to the at least one detector in order to separate, identify and quantify substances in the sample and transmit results from the at least one detector to the LC system for collection and analysis.
