Definitions

  • the invention relates to a device for removing liquids, which can be used in particular in the microliter range.
  • a removal system which consists of a desorption sample container and a needle unit.
  • This container is covered at its frontal opening with an end cap having a through hole.
  • the through-bore of the end cap has a closure made of PTFE with a through-hole through which a trained as a hollow needle or cannula needle unit for sampling is pierceable.
  • the inner diameter of the through hole is equal to or smaller, preferably slightly smaller than the outer diameter of the needle unit, whereby a sealing effect along the outer circumference of the needle unit comes about upon import of the needle unit.
  • This known removal system in turn has a pierceable septum in the form of a closure, which is fastened by means of a crimp cap on the container. Once the closure is pierced, the crimp cap and thus the closure is removed, which therefore obviously does not close and thus is only suitable for single use, so for the mere closing of the container.
  • the invention is therefore based on the object to provide a device for the removal of liquids available, in which after the first removal of solution sample loss can be reliably prevented by evaporation of volatile solvent.
  • a device for removing liquid which can be preferably used in the microliter range, which has a container, a lid for closing the container with a bore, and a removal cannula with a lateral opening at the distal end, wherein the cannula sealing, however slidably Jerusalemiiehmbar along its longitudinal axis in the bore Jerusalemiiehmbar, and the lid has a thickness such that the lateral opening of the cannula when removing the cannula from the container is completely sealed in the lid.
  • the cannula can be passed through the hole provided in the lid directly into the interior of the container, whereby the lateral opening of the cannula can be in fluid communication with the outside environment after the lid has passed through it.
  • the cannula can then be used to remove solution which is present inside the container.
  • the cannula can be guided to the bottom of the container, wherein almost all the liquid can be absorbed by the Soöfmung.
  • the cannula is withdrawn until the side opening of the cannula is within the lid.

  • the lid has a thickness which is greater than the axial length of the lateral opening of the cannula, preferably twice the length or more.
  • the distance of the lateral opening from the cannula tip is advantageously chosen equal to the diameter of the opening or larger.
  • the cannula needle itself is directly connected to the syringe body, i. integrally formed.
  • the cannula needle has a coupling, usually a screw or bayonet coupling with the syringe body.
  • a coupling usually a screw or bayonet coupling with the syringe body.
  • the proximal end of the cannula is provided with a screw coupling unit in the form of a screw cap, which can be screwed onto a complementary screw thread on the syringe body.
  • a snap coupling is provided between the proximal end of the cannula and the syringe body, which can be used for a quick coupling or decoupling of the cannula with the syringe body.
  • the distal formation of the cannula can be uncritical, ie it can be provided with a lateral bore or else with a front bore.
  • this cannula formation can also be used for purposes other than for the purposes of the invention. It is particularly suitable when the sampling system according to the invention is to be operated in conjunction with an automated sample introduction system of an analytical device or in conjunction with a laboratory robot for automated sample preparation.
  • PTFE polytetrafluoroethylene
  • PTFE also has favorable sealing properties, provided it is used in a screw cap for screwing onto a container with a corresponding screw end.
  • the lid can be replaced with the cannula therein, for example, by a conventional lid without bore, the lid is preferably designed screwed to the container and optionally a PTFE disc is used as an additional sealant.
  • the nominal diameter of the bore or the diameter of the bore of the lid is equal to or slightly smaller than the outer diameter of the cannula.
  • minor is a maximum of 10%, advantageously at most one
  • the sampling device additionally has a mechanical safeguard to prevent leaks due to unintentional complete withdrawal of the cannula from the container and undesired contamination by accidentally exchanging the needles belonging to different containers.
  • a fuse may for example consist of a spacer having a mounted on the top of the lid linkage or from a nose at the distal end of the cannula. Other embodiments which accomplish the same object are known in the art and skilled in the art.
  • Figure 1 is a schematic cross-sectional view in the parts A-D of a device for withdrawing liquid, wherein
  • Figure IA illustrates a syringe assembly according to the prior art
  • FIG. 1B shows a syringe arrangement which can be used according to the invention
  • FIG. 1C shows a cross-sectional view of a cannula, which is provided in a sealed state in a container, with an enlarged partial section, in which the inserted cannula is shown,

  • a syringe 10 is shown in the image A according to the prior art, the needle tip 12 is opened.
  • This syringe 10 is formed in one piece and is not suitable for the purposes of the invention, since it can be used only for single use for sampling and then must be discarded.
  • a Traumhahmenan Aunt 14 is shown in the form of a two-piece syringe assembly 15, which consists of a syringe body 16 with a syringe channel 18 and a scale 20, wherein in the syringe channel 18, a punch 22 is immersed with an actuating member 24.
  • a screw 28 At the opposite end 26 of the syringe body 16 is provided with a screw 28 which has an external thread 30.
  • the syringe channel 18 passes through the screw 28, which is expanded to receive the proximal end 32 of the cannula 34 accordingly.
  • This proximal end 32 in this case has a screw cap 36 with an internal thread which cooperates with the external thread 30 of the syringe body 16 complementary, wherein in the screwed state, the cannula channel 38 is aligned with the syringe channel 18 and forms a flow path.
  • the actuating member 24 is shown in Figure IB as a handpiece, which allows manual movement of the punch 22. If an automatic dosing system (not shown in the figure) is used, a corresponding connection to the mechanically moving parts of such a system can also be installed at this point.
  • the distal end 40 of the cannula 34 is closed and either rounded or pointed, but preferably pointed, as shown in particular from the enlarged view of Figure IC and Figure ID is apparent. Adjacent to the distal end, a cannula opening 42 is recessed laterally in the cannula wall, which forms the aforementioned flow path, formed by the cannula channel 38 and the syringe channel 18, to the interior of a container 44.
  • the container 44 is not shown in detail, with only the outer wall 46 and the container wall 48 are of interest.
  • a lid 50 is placed, which is designed as a screw cap.
  • the lid 50 covers the container 44 with its main lid part 52 and thus seals the container in the screwed-on state.
  • main lid part 52 is according to the embodiment shown in Figure 1 axially from a ring member 54 which has on the inside an internal thread 56 which can cooperate with a complementary external thread 58 of the container 44 such that the main lid member 52 sealingly cooperates with the container 44.

  • the main lid portion 52 is penetrated with a bore 60 which creates a flow connection from the environment to the container interior 48.
  • the cannula 34 can be pushed through, wherein it can be locked according to the enlarged views in Figure 1 either in the lid 50 or, as shown in Figure IC *, is advanced to the deepest container.
  • the nominal diameter or diameter of the bore 60 is designed so that it corresponds at most to the outer diameter of the cannula 34.
  • the nominal diameter is somewhat smaller, but not more than 10% of the nominal diameter of the cannula 34.
  • the thickness x of the main lid portion 52 is at least twice as large as the diameter y of the lateral cannula opening 42, advantageously more than three times. This ensures that the cannula 34 can be adjusted to seal the container 44 with respect to the environment without difficulty. This is especially true for an automatic feeding and retracting the syringe assembly 14 by means of a dosing, not shown.
  • the material of the cover 50 is advantageously made of PTFE, on the one hand sufficiently rigid to produce a satisfactory sealing effect with the container 44, but has excellent sliding properties, so that the cannula 34 only with low friction, even with tight tolerances of the bore 60 in the container can be pushed, but not jammed in the bore 60.
  • Essential to the invention is therefore that the lateral opening 42 closes the container interior tightly against the environment over a longer period with locked opening 42 in the main lid part 52, so that no volatile solvents can escape from the container 44.
  • FIG. 1C shows a special container arrangement which has a microliter vessel 62, to which a reflux pipe 64 adjoins.
