Abstract: The present invention concerns an apparatus (100) for transferring a vial (200) from a first station (301) to a second station (302), comprising a stock (101) of vials in said first station, a mobile arm (1) provided with at least three gripping elements (2a-2d) 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 (2a-2d) have a magnet (5), 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.

Abstract: The present invention relates to an apparatus (1) for sampling the headspace, comprising: a mobile station (2) provided with a plurality of housing seats (21) to house a plurality of containers (100) for sampling the headspace; an oven (3); a blocking device (4) comprising at least one first mobile element (41) that moves between a first position adapted to prevent a container (100) from passing from the mobile station (2) to the oven (3), and a second position adapted to allow a container (100) to pass from the mobile station (2) to the oven (3); at least one first sensor (5a) placed upstream of the first mobile element (41), to detect the presence of a container (100) in a housing seat (21); a movement element (6) moving between said mobile station (2) and the oven (3), the movement element being configured to move a container (100) from the mobile station (2) to the oven (3).

Abstract: 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 (a) 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.

Abstract: The invention relates to a device for positioning and holding one or more chromatographic column lengths being subjected to one or more jets of fluid to change the temperature, especially in a modulator for GC×GC. The device comprises one or more V-shaped seats in which the column is housed, and pushed within the groove.
