Description: SAMPLE VIAL WITH TRANSPONDER Title: Vial, method for the use of a vial for the purpose of performing an analysis on a sample, and a system for practicing the method according to the invention using a vial according to the invention. The invention relates to a vial provided with an outer vial and an inner vial, wherein, in the space enclosed by the inner vial and the outer vial, a memory chip is included. Such a vial is known from Figure 2 of the European patent application EP-A-0 875 292. It is known that vials are disposable products. It is therefore highly important to the customers that the price of a vial be low. Heretofore, the vial known from the European patent application has been too expensive to be used in practice, notably because the entire vial, the memory chip included, has to be thrown away after use. To the present day, the prices of the memory chips do not allow this. As is known from the European patent application mentioned, it is of great importance that, during use, the sample cannot be separated from the memory chip, so that confusion of data stored relative to a particular sample in a particular memory chip, with data of another sample cannot occur. Such confusion has indeed always been completely precluded with the known vial, however, as indicated hereinabove, the use of the known vial was so costly that, up to the present day, this has impeded its introduction in practice. The invention contemplates a vial, the use of which is considerably less expensive than the known vial, while it is still guaranteed that the data of a particular sample which are stored in a memory chip of a vial, are never confused with the data of another sample. Hence, a vial with which no fraud can be committed and which meets the standards set by the various government agencies, such as, for instance, the Food and Drug Administration, more in particular FDA21CFR11, the Environmental Protection Agency, and with the aid of which the requirements can be met which are set by Good Laboratory Practice (GLP), Good Manufacturing Practice (GMP) and/or Standard Operation Practice (SOP). To this end, the vial of the type described in the preamble is characterized according to the invention in that the inner vial and the outer vial are connected to each other with the aid of a connecting ring, so that they are detachable from each other, the connecting ring forming a seal in that it can only be broken by destruction, the memory chip being connected to the outer vial. Such a vial is relatively inexpensive in use in that the outer vial with the memory chip can be used over and over again and only the inner vial needs to be replaced after use. After analysis of the sample present in the inner vial, the inner vial can be separated from the outer vial and a new inner vial can be placed in the outer vial. Such recycling can take place in the laboratory itself, but can also take place in a recycling facility, especially equipped to that end. Such a recycling facility can, for instance, be set up by the producer of the vials according to the invention. According to a further elaboration of the invention, the connecting ring can have a substantially cap-shaped configuration with a side wall and a top wall, a lower edge of the side wall being folded around a collar of the outer vial, while the inner vial is enclosed between the collar of the outer vial and the top wall of the connecting ring. The top wall of the connecting ring can be provided with an opening, so that the interior of the inner vial is accessible. Optionally, the filling opening of the inner vial can be provided with a septum for closure thereof. Then, evidently, this septum closes off the opening in the top wall of the connecting ring. When a sample is to be brought into or taken out of the inner vial, the septum is pierced with a needle, with the aid of which the sample can be added or removed, respectively. Such a septum is known per se and the skilled person knows the operation thereof. According to a further elaboration of the invention, in the space enclosed between the inner vial and the outer vial, further an antenna can be included, which is connected to the memory chip to form a transponder. With such a transponder, the memory of the memory chip can be written on and/or read out remotely. According to an alternative, further elaboration of the invention, the memory chip can also be provided with contact points or proximity sensors, arranged for exchanging information by direct or virtually direct contact between the memory chip and read/write equipment. The invention also relates to a method for the use of a vial for performing an analysis on a sample. The object of the method is to enable the performance of an analysis using a vial provided with a memory chip such as, for instance, a transponder, while the costs of the use of such a chip still remain limited. To that end, the method according to the invention comprises the following steps: providing a vial according to the invention; placing a sample in the inner vial; storing an identification, coupled to the sample, in the memory chip of the vial; - analysing the sample; storing the analysis data of the respective sample; after storage of the analysis data, breaking the connecting ring and separating the outer vial and the inner vial. When storing the analysis data, these analysis data are coupled to the identification mentioned. Storing the analysis data can take place in the memory chip of the vial but also in a laboratory information management system (LIMS) or like database. However, the analysis data should always be coupled to the unique identification of the sample. As the connecting ring is only broken after storage of the analysis data and the outer vial is separated from the inner vial, it is prevented that an identification of a sample, stored in the memory chip of the vial in which the sample is present, will, at any given time, inadvertently, or as the result of fraud, be coupled to a different sample. The fact is that sample and identification are coupled to each other until after storage of the analysis. This coupling is physical with the aid of a connecting ring serving as a seal. When the coupling is broken this is visible as the connecting ring has to be destroyed to that end. According to a further elaboration of the invention, the method can further comprise at least one pre-analytic step, such as centrifuging, weighing or the like. According to a further elaboration of the invention, it is preferred that after breaking the connecting ring and separating the outer vial and the inner vial, a new inner vial is placed in the outer vial. Also, at that moment, or afterwards, the memory of the memory chip can be erased. Optionally, the memory chip can be loaded with the various pre- analytical and analytical operations the sample has to undergo, the pre- analytical and analytical processing stations being provided with read/write devices for reading out information from and writing information in the memory chip. The various pre-analytical and analytical processing stations can be provided with control software and displays, the displays providing information to the user about the operations to follow, depending on the information coming from the memory chip of the respective vial. Besides providing information, the control software of the processing stations can be designed such that it prevents execution of an operation which is not programmed in the memory chip, and gives directions to the user about the operation which does have to be performed. Further, the invention relates to a system for practising the method according to the invention using vials according to the invention, the system comprising at least a number of processing stations for performing an operation on a sample present in a vial, at least one of the processing stations being provided with a read write station for, respectively, reading out information from the memory chip of a vial and writing information in the memory chip of a vial, the system being provided with a control provided with control software arranged for processing the information coming from the memory chip. Such a system offers the advantage that the analysis can be carried out without confusion of samples while, still, use is made of vials with a memory chip, such as for instance a transponder. According to a further elaboration of the invention, it is preferred that the various processing stations are provided with displays, the software providing the system user, via the displays, with information about the operations to be performed, which a particular vial has to undergo. Such a system can even be operated by relatively unskilled analysts without this lack of training leading to incorrect pre-analytical and analytical operations. Optionally, the various processing stations can even be controlled by the control such, that these processing stations perform the operation dictated by the control, suitable for the respective sample at the respective processing station. It will be clear that the processing stations can comprise pre-analytical processing stations, such as, for instance, centrifuges and weighing devices, and analytical processing systems, such as, for instance, gas chromatographs and mass spectrographs, all known per se. Hereinbelow, the invention will be elucidated on the basis of two exemplary embodiments of vials according to the invention which can be used with the method according to the invention and in the system according to the invention. Fig. 1 shows a cross sectional view of a first exemplary embodiment of a vial; and Fig. 2 shows a cross sectional view of a second exemplary embodiment of a vial. Both Figures show a vial 1, 51, which are provided with an outer vial 2, 52 and an inner vial 3, 53. In the space R enclosed by the outer vial 2, 52 and the inner vial 3, 53, a memory chip 4, 54 is included. In the present exemplary embodiments, this memory chip 4, 54 is connected to an antenna 5, 55 designed as a coil. More in particular, the combination shown of the memory chip 4, 54 with antenna 5, 55 is a transponder whose memory can be loaded with data and be read out remotely. It is clearly visible that the memory chip 4, 54 and the antenna 5, 55 are connected to the outer vial. To that end, they are both embedded in a plastic layer 6, 56, which, in the present exemplary embodiments, is designed as a cylindrical ring 6, 56, connected with an outer surface to the inner wall of the outer vial 2, 52. It is noted that instead of or in addition to the antenna 5, 55, the memory chip 4, 54 can be provided with contact points or proximity sensors arranged for exchanging information by direct contact or virtually direct contact between the memory chip and the read/write equipment. In the present exemplary embodiments, the inner vial 3, 53 is a disposable and the outer vial 2, 52 with memory chip 4, 54 is reusable by fitting a new inner vial 3, 53 therein. In the present exemplary embodiments, the outer vial 2, 52 comprises a substantially cylindrical body 7, 57, provided at the top with a neck-shaped constriction 8, 58. The constriction 8, 58 links up with an outer vial collar 9, 59. The inner vial 3, 53 comprises a substantially cylindrical body 10, 60 with a filling opening 11, 61 at one end. The body 10, 60 of the inner vial 3, 53 bounds an inner space S, which serves for receiving a sample. At the filling opening 11, 61, the inner vial 3, 53 is provided with an inner vial collar 12, 62. In a fitted condition, the inner vial collar 12, 62 rests on the outer vial collar 9, 59. In both exemplary embodiments, the outer vial collar 9, 59 links up with a cylindrical wall 13, 63 whose inner diameter is such that the inner vial collar 12, 62 is receivable therein. The outer vial 2, 52 is connected with the inner vial 3, 53 with the aid of a connecting ring 14, 64, such that they are mutually detachable, the connecting ring 14, 64 forming a seal in that this can only be broken by destruction. The connecting ring 14, 64 has a substantially cap-shaped configuration with a side wall 15, 65 and a top wall 16, 66. A lower edge 17, 67 of the side wall 15, 65 is folded around the collar 9, 59 of the outer vial 2, 52. The inner vial 3, 53 is enclosed between the collar 9, 59 of the outer vial 2, 52 and the top wall of the connecting ring 16, 66. In both exemplary embodiments, the top wall 16, 66 of the connecting ring 14, 64 is provided with a central opening which gives access to the filling opening 11, 61 of the inner vial 3, 53. In the present exemplary embodiments, the connecting ring 14, 64 is designed in aluminum. Aluminum offers the advantage that it can be easily folded with the aid of a hand tool. Moreover, removing an aluminum connecting ring 14, 64 is not particularly complicated. The vials 1, 51, generally designed in glass, undergo the removal of a connecting ring 14, 64 without these vials 1, 51, thereby sustaining damage. Upon removal of the connecting ring 14, 64, the connecting ring 14, 64 itself, however, is irreparably damaged. Both exemplary embodiments are further provided with a septum 18, 58. The exemplary embodiments are distinguished from each other by the manner in which the septum 18, 68 is fitted. In the exemplary embodiment of Fig. 1, the inner vial 3 is provided with an inner vial cap 19, which comprises a top wall 19a with a central opening, a side wall 19b contiguous to the top wall 19a, while a lower edge 19c of the side wall 19b is folded around a lower side of the inner vial collar 9. The septum is enclosed between the top wall 19a of the inner vial cap 19 and a top wall of the inner vial collar 12. This inner vial 3, in itself closed off by a connecting cap 19 and a septum 18 is connected to the outer vial 2 with the aid of the connecting ring 14. In the exemplary embodiment of Fig. 2, the septum 68 is clamped between the top wall 66 of the connecting ring 64 and a top wall of the inner vial collar 62. To ensure a clearance-free connection between the inner vial 53 and the outer vial 52, between the collar 62 of the inner vial 53 and the collar 59 of the outer vial 52 a distance ring 69 is included. This distance ring 69 can be designed in aluminum, plastic or rubber. For the method of the use of the vial or the analysing system in which the vial can be applied, reference is made to the introduction to the specification of the present application. It will be clear that the invention is not limited to the exemplary embodiments described but that various modifications within the framework of the invention are possible.
