Abstract: Vial comprising an outer vial and an inner vial, wherein in the space enclosed between the inner vial and the outer vial a memory chip is included, characterized in that the inner vial and outer vial are connected to each other with the aid of a connecting ring, such that they are detachable from each other, the connecting ring forming a seal in that this can only be broken by destruction, the memory chip being connected to the outer vial. The invention also relates to a method for the use of a vial for the purpose of performing an analysis on a sample and to a system for practicing the method using vials according to the invention.

Abstract: A device for storing and/or treating chemicals is described. The device includes a glass casing provided with a receiving cavity for storing chemicals therein, and further includes a transponder having a memory, the transponder being arranged in the device such that it cannot be affected by the chemicals.

Abstract: An assembly for desorbing sampling tubes comprises a gas chromatograph known per se provided with an injector. The sampling tubes are provided with an inflow opening and an outflow opening. The assembly comprises an adapter which is placed in the injector and which is provided with a chamber which is bounded by a heat conducting housing. The adapter is arranged for placing a sampling tube in the chamber thereof, while in a condition of a sampling tube wherein it is placed in the adapter, the inflow opening thereof is in fluid communication with a first carrier gas supply duct, while the outflow opening of the sampling tube is in fluid communication via the injector with a gas chromatography column disposed in the gas chromatograph.

Abstract: The invention relates to a sampling tube comprising a glass tube (2) with two closed ends (3), the sampling tube (1) being filled, at least over a portion of the length of the tube, with an adsorption material (4), the adsorption material (4) being confined between two gas-permeable plugs (5). According to the invention, the plugs (5) are manufactured from completely inert material and no non-inert material is present in the sampling tube. The invention further relates to a sampling tube whose ends (3) are closed off with sealing caps (6) which are manufactured from TEFLON.RTM., the sealing caps (6) comprising an end portion (7) and a cylindrical stopper (8) integrally connected therewith, which stopper (8), at least locally, has an external diameter receivable with a proper fit in the interior of the glass tube (2), the end portion (7) having a diameter greater than the internal diameter of the glass tube (2). The invention further describes a method for manufacturing such sampling tubes.

Abstract: Device for connecting a first duct of a very small diameter, such as for instance a needle or a capillary column, to a second duct, wherein the device comprises a receiving part and a sealing element, wherein the receiving part is provided with a duct bore in which the first duct is slidably receivable, wherein the receiving part is also provided with a sealing-element bore which intersects the duct bore and in which the sealing element is slidably received, wherein the sealing element is provided with a recess, wherein the sealing element is adapted to assume a sealing position in which the duct bore is sealed, and is adapted to assume a connecting position in which the two duct bore parts on either side of the sealing-element bore are in fluid connection with each other via the recess, wherein the sealing element is biased in the sealing position by a spring under spring action.

Abstract: A closing element intended for closing off an end of a capillary gas chromatography column comprises a closing body provided with a blind hole, which tapers over at least a portion of the length thereof, and the walls of the tapering portion of the hole include an angle with the centerline of the hole, this angle being so small that upon placement of the closing element on the end of the capillary gas chromatography column, a self-locking engagement between the end of the column and the closing element occurs. The closing element is manufactured from a form-retaining, inert, gastight material.
