Abstract: The present techniques, including methods and systems, relate to obtaining or producing a concentrated gas sample from a non-concentrated gas sample with a trap that is not inline with (or indirectly connected to) a chromatographic method, and injecting a controlled volume of the concentrated gas sample in a sample loop including a valve or similar chromatographic component through a sample line. The method includes preparing the concentrated gas sample from the non-concentrated gas sample with a trap; controlling a temperature of an internal volume of the trap to reach a release temperature; injecting the concentrated gas sample in a sample line towards a sample loop, the sample line and sample loop being at a sub-atmospheric pressure; and operating the sample loop to release the concentrated gas sample contained in the sample loop in a chromatographic method, wherein the trap is not inline with the chromatographic method.

Abstract: A discharge-based photo ionisation detector (PID) for use with gas chromatography systems is provided. The PID includes a discharge zone in which a plasma can be generated, resulting in the emission of energetic photons. The PID further includes an ionisation zone in which the gas sample to be analysed is bombarded by the photons created in the discharge zone, photo ionising the impurities in the gas sample. The generated current is measured in order to measure the concentration of impurities in the gas sample. Plasma localizing of the plasma in the discharge zone and optical monitoring of the emission from the plasma in the discharge zone may be provided. Methods using such a PID with a split input from a chromatography column or with inputs from two different chromatography columns are provided.

Abstract: A ball valve is provided. The ball valve includes at least one load varying mechanism provided in the static body assembly. The load varying mechanism includes a biasing member pressing one of the ball seat seals against the outer surface of the ball of the ball valve with a variable sealing load force applied on the ball, toward the ball and coaxial with the direction of the fluid. The load varying mechanism also includes a movable member operatively connected to a cam and to the biasing member, a rotation of the cam translating the movable member coaxially to the direction of the fluid, in order to variably load the biasing member toward or away from the ball, based on the different positions of the ball.

Abstract: Methods and systems for measuring, in a gas stream, an analyte concentration level from a gas chromatography elution peak outputted by a gas chromatography system are provided. The method includes receiving an analyte signal representative of the gas chromatography elution peak in the time domain, converting the analyte signal from the time-domain to the frequency domain, in the frequency domain, preprocessing the analyte signal to distinguish frequencies of the analyte signal, integrating the analyte signal after preprocessing to obtain a redressed analyte signal in the time domain, the redressed analyte signal having a substantially Gaussian shape, and processing the redressed analyte signal to obtain the analyte concentration level. The system includes a detector operable for generating the analyte signal and one or more processors configured for preprocessing and integrating the analyte signal to obtain the redressed analyte signal and processing the redressed analyte signal to obtain the analyte concentration level.

Abstract: An actuator for actuating a plunger of a valve is provided. The actuator has an inlet and includes first and second hollow caps. A main actuation assembly is provided between the caps. The main actuation assembly includes a deformable diaphragm; first and second chambers, static sealing elements and a main piston movable between actuated and unactuated positions. A biasing mechanism biases the piston in the unactuated position. When pressurized gas is flown through the inlet and/or drawn from the outlet of the actuator, the first chamber expands, moving the main piston from the unactuated position to the actuated position, an actuating stem connected to the main piston thereby sliding within a channel provided in the bottom cap. Stackable actuating assemblies can also be used between the caps. Using static sealing elements advantageously avoids friction between moving parts.

Abstract: There are provided techniques, including methods and systems, for chromatographically analyzing a test sample. The techniques include obtaining a sample chromatogram of the test sample with a chromatography system, the chromatography system including a detector having an adjustable response factor. The techniques also include adjusting, while obtaining the sample chromatogram, the response factor of the detector based on a compensation signal for compensating expected chromatographic artefacts to obtain an artefact-compensated sample chromatogram. The disclosed techniques allow compensating for chromatographic artefacts, which include baseline drift(s) and/or peak tailing(s), during acquisition of chromatograms.

Abstract: A valve comprising a valve cap, a valve body and a diaphragm positioned between the valve cap and the valve body. The valve further has a plurality of plungers movable, by an actuation system, between a closed position where the plunger engages the diaphragm, and an open position where the plunger is disengaged from the diaphragm. Each plunger comprises a base section connected to the actuation system and having a head projecting away therefrom; a top section extending between the base section and the diaphragm, the top section having a foot in contact with the head of the base section; and a biasing mechanism biasing the top section away from the diaphragm when the plunger is in the open position. Tangential contact points may also be provided between components of the actuation and the biasing mechanism for preventing a misalignment of the actuation system within the valve body.

Abstract: An emission-based detector for use in conjunction with capillary chromatography or other applications involving a gas sample having a small volume is provided. The detector is based on optical emission from a plasma medium. An optical cartridge or other detection and/or processing means may be provided to receive and analyse the emitted radiation and thereby obtain information on the gas to be analysed. The emission-based detector includes a gas inlet, a gas outlet and a capillary channel which is in fluid communication with the gas inlet and gas outlet. The capillary channel acts as the plasma chamber. Preferably, the capillary channel has transversal dimensions of the same order as the cross-section of typical chromatography capillary columns and defines a winding path within the detection area. A multi-cell emission-based detector and a method of analysing a gas sample using multiple detection cells are also provided.
