The present invention relates to an apparatus () for sampling the headspace, comprising: a mobile station () provided with a plurality of housing seats () to house a plurality of containers () for sampling the headspace; an oven (); a blocking device () comprising at least one first mobile element () that moves between a first position adapted to prevent a container () from passing from the mobile station () to the oven (), and a second position adapted to allow a container () to pass from the mobile station () to the oven (); at least one first sensor () placed upstream of the first mobile element (), to detect the presence of a container () in a housing seat (); a movement element () moving between said mobile station () and the oven (), the movement element being configured to move a container () from the mobile station () to the oven ().

Apparatus having one or more sensors for sampling the headspace and process for sampling the headspace

The present invention concerns an apparatus () for transferring a vial () from a first station () to a second station (), comprising a stock () of vials in said first station, a mobile arm () provided with at least three gripping elements (-) movable between one another in a controlled way at least between a first and a second position, wherein the free ends of at least part of said gripping elements (-) have a magnet (), and wherein the area of the polygon (P) having as vertexes said free ends in said first position is smaller than the area of the polygon (P) having as vertexes said free ends in said second position.

Apparatus for transferring a vial from a first station to a second station

Process for sampling the headspace, comprising the steps of: (i) preparing a container () containing a substance in the liquid phase (), a substance in the gaseous phase (), a substance to be analyzed () initially at least partially contained in the substance in the liquid phase (), wherein the substance in the liquid phase () has a contact surface (S) contacting the substance in the gaseous phase; (ii) constraining said container () to a supporting element () rotatable around a rotation axis (A); (iii) rotating said supporting element () 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 (); (iv) stopping the rotation of said supporting element (); (v) collecting a sample of the substance to be analyzed, in the gaseous phase.

Process and device for sampling the headspace

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.

Sampling method for the chromatographic analysis of the headspace

Chromatography column assembly of the direct heating type, comprising at least a capillary column, at least a tubular structure which envelops the capillary column and is coaxial with it, means to directly heat the column, means to detect the temperature of the column and one or more electrically insulating covering elements, wherein the tubular structure comprises a plurality of tubular meshes each formed of a plurality of filaments woven together (FIG.).

Chromatography column assembly

A direct-heating column assembly for chromatography, includes at least one capillary column and at least one element made of electrically conductive material in contact with the capillary column. The element includes a plurality of filaments woven together to form a tubular mesh that uniformly envelops the outer surface of the capillary column both in radial and longitudinal directions.

Chromatography column assembly with woven tubular mesh heater element

A method and an apparatus for chromatography are described, wherein at least one element in electrically conductive material is provided to heat the capillary column in a direct way and wherein the control of the temperature is carried out according to a mathematical model having a component of predictive type, or Feed Forward type, that describes the thermodynamic behavior of the assembly comprising the electrically conductive element and the column at least as a function of the thermal resistance and the thermal capacity of the assembly thus constituted in order to regulate the supply of electrical power supplied to the conductive element.
