A gas analyzer system uses an ionization source, which can be a hot cathode ionization source. A magnet assembly is positioned to define a magnetic field, which permits separation of ion components based on their mass to charge ratio. An ion beam deflector is used, such as a pair of deflector plates, which can scan ion components across a detector. The ion beam deflector defines a deflection electric field across the magnetic field and across a direction of travel of the ions emitted from the ionization source.

Methods for determining the hardness and/or ductility of a material by compression of the material are provided as a first aspect of the invention. Typically, compression is performed on multiple sides of a geologic material sample in a contemporaneous manner. Devices and systems for performing such methods also are provided. These methods, devices, and systems can be combined with additional methods, devices, and systems of the invention that provide for the analysis of compounds contained in such samples, which can indicate the presence of valuable materials, such as petroleum-associated hydrocarbons. Alternatively, these additional methods, devices, and systems can also stand independently of the methods, devices, and systems for analyzing ductility and/or hardness of materials.

A battery pack leakage detection system and detection method are provided. The system includes a test container, a gas filling subsystem, a gas stirring subsystem and a test analysis subsystem. The method can test the sealing performance of the battery pack under the atmospheric pressure, so that the battery pack can meet the corresponding sealing grade requirements of IP67 and IP68. The method not only solves the problem that the traditional gas detection method cannot meet the test requirements of IP67 and IP68 due to insufficient measurement precision, but also solves the problem that the traditional vacuum helium detection method will damage the battery cells in the battery pack.

According to one configuration, an example surveillance system includes a sensor device, analyzer hardware, and processing hardware. During operation, the sensor device scans a monitored location and generates scan data. In one embodiment, the scan data (such as distance-based data) indicates (defines) surface textures of one or more objects present at the monitored location (such as a location of interest) based on distance measurements. The analyzer hardware analyzes the scan data and change in surface textures. The controller hardware: i) generates a communication based on the detected surface textures, and ii) transmits the communication to a remote station.

The present invention relates to a method and a device for determining the robustness and tolerance of pre-filled containers, in particular pre-filled syringes (PFS) against accidental movement of flexible parts, specifically tip cap and/or plunger movement due to external influences by measuring the leakage rate of a test medium in correlation to a movement of a flexible parts.

Tracer gas sensing device comprising a gas discharge cell having cell walls defining a discharge volume and a tracer gas inlet into the discharge volume, an optical spectrometer arrangement having a radiation source on a first side of the discharge cell for emitting radiation into the discharge cell and a radiation detector on a second side of the discharge cell opposite to the first side for detecting radiation which was emitted by the radiation source through the discharge volume, and electrodes on opposing sides of the discharge cell for generating a plasma within the discharge cell, said electrodes being unexposed plasma electrodes. The discharge cell may be a dielectric barrier discharge cell and the electrodes may be powered by an AC power source.

A spray device for detecting leaks is provided, including: a duct including an inlet configured to be connected to a tracer gas source, and an outlet; a valve interposed between the inlet and the outlet; a casing receiving the duct and the valve; at least one probe arranged in the duct, the at least one probe being configured to measure a parameter revealing a presence of the tracer gas in the duct; and at least one information device borne by the casing, configured to provide information on the presence of tracer gas in the duct in relation to a measurement performed by the at least one probe.

A system and method to discriminate between a first preselected gas and at least one other preselected gas use of an absorption spectroscopy analyzer that includes a Herriott cell and a temperature sensitive light source. The light source operates at a temperature that emits a beam at a wavelength that corresponds to high absorption by a first preselected gas. When a predetermined level of this gas is detected in a gas sample, the analyzer changes the operating temperature of the light source to emit a beam at a wavelength that corresponds to high absorption by a second preselected gas. The second preselected gas can be a different isotope of the first preselected gas.

Systems, methods, and devices for detecting leaks in chromatography systems are disclosed. The leak detection system includes a sealable compartment disposed to surround at least one component of a chromatography system. The detector is in communication, e.g., fluid communication, with an interior of the sealable compartment and configured to detect the leak by various mean including the presence of liquid or the presence of vapor, or both within the sealable compartment.
