摘要： The invention concerns a method for preparing a sample to be introduced in a chromatographic analysis system from the headspace of a vial, by introducing a pressurized inert gas in said headspace, controlling the pressure or flow, and subsequently by discharging said pressure from the headspace through a loop having constant volume and through a discharge duct provided with a valve, the discharge duct branching with respect to the feed duct. To eliminate the drawbacks of the known methods, during the step of discharging the pressure, the feed duct is kept open and the pressure in said loop is controlled by detecting the feed and/or discharge pressure.

摘要： Process for sampling the headspace, comprising the steps of: (i) preparing a container (1) containing a substance in the liquid phase (2), a substance in the gaseous phase (3), a substance to be analyzed (4) initially at least partially contained in the substance in the liquid phase (2), wherein the substance in the liquid phase (2) has a contact surface (S) contacting the substance in the gaseous phase; (ii) constraining said container (1) to a supporting element (10) rotatable around a rotation axis (A1); (iii) rotating said supporting element (10) at such an angular velocity to tilt said contact surface (S) by an angle (α) of at least 20 degrees with respect to a plane (H) parallel to the bearing surface of the supporting element (10); (iv) stopping the rotation of said supporting element (10); (v) collecting a sample of the substance to be analyzed, in the gaseous phase.

摘要： An autosampler for sampling liquids is disclosed. The autosampler may comprise a holder 13 for holding at least one vial 30, a syringe 20 for withdrawing a liquid sample from the at least one vial 30, an actuator 21 for actuating the syringe 20, a housing 11 for accommodating the syringe 20 and the actuator 21, and a magnifying lens 16 attached to the housing 11 to facilitate visual inspection of the syringe 20 during use. The magnifying lens 16 may be accommodated in a door 14 of the housing 11, behind or integrated in a transparent section of the door 14. The autosampler may be used in conjunction with a chromatograph, such as a gas chromatograph, a liquid chromatograph, or an ion chromatograph.

摘要： A connector 200 for a gas chromatography (GC) column includes a receiving portion 202 coupled to a ferrule receiving conical surface and a column holding portion 204. The column holding portion 204 includes a column guide tube 212 and a column retention spring 214 to fix the axial position of the column and a compression spring 216 to bias the column guide tube 212 towards the ferrule receiving conical surface. When connected, a ferrule 222 is compressed between the ferrule receiving conical surface and the column guide tube.

摘要： Described are techniques for performing automated maintenance evaluations on a gas chromatograph (GC) or a gas chromatograph-mass spectrometer (GC-MS). Systems and methods are described for directing an injector 106 of a GC or GC-MS instrument system 100 to autonomously inject a diagnostic material sample 114 into a material analysis chamber and initiate a scientific analysis to formulate a set of results. The systems and methods further include the instrument system analyzing the set of results generating one or more output reports.
