Definitions

  • the invention relates to an arrangement for chemical analysis and synthesis in columnar reaction devices according to the preamble of claim 1.
  • HPLC High Pressure Liquid Chromatography
  • This process which was developed from column chromatography, is mainly used for the rapid separation of mixtures of substances.
  • the separation performance of a porous material (stationary phase) located in a column is used.
  • the reaction solution hereinafter referred to as the mobile phase
  • a valve system is connected upstream of the pump arrangement. In this case, the pump arrangement and the valve system can be controlled via a control device.
  • Such devices are primarily used as analyzers.
  • HPLC systems can also be used for synthesis processes.
  • molecular chains for example oligonucleotides, are synthesized in the so-called heterogeneous phase on polymers, the polymeric support usually being in the form of fibers or spheres in the columnar reaction devices.
  • the object of the invention is to provide an arrangement which enables several components
  • Processes i.e. also analysis and synthesis processes, can be controlled simultaneously and independently of one another, whereby at the same time a free configuration of the individual systems is possible, and with which, in addition to the control of the processes, an evaluation, e.g. a numerical evaluation or the development of other conditions can be carried out.
  • an evaluation e.g. a numerical evaluation or the development of other conditions
  • Embodiments of the invention are characterized in the subclaims.
  • the advantages associated with the invention consist essentially in the control of several processes that run simultaneously and independently of one another, in one process. Improvement with regard to the configurability of the systems and a relief of the central control part, which is usually implemented by a microcomputer.
  • Fig. 3 shows a second embodiment of the invention
  • Fig. 4 shows an example of a variable system configuration.
  • the arrangement for an HPLC system shown in simplified form in block form in FIG. 1 has four feeds for the mobile phase M.
  • the feeds are connected to a pump P via a valve arrangement V with four valves.
  • This is connected to the columnar reaction device S via an injection system I.
  • the control of the individual valves in the valve arrangement V and the control of the pump P takes place via the control device K.
  • This can be a microcomputer that controls the processes provided for a synthesis process. Practically, this means that the setting and monitoring of the valves and the pump parameters is carried out by the control device K under program control.
  • a detector device D assigned to the reaction device S determines current measurement results and provides corresponding signals.
  • FIG. 2 shows an exemplary embodiment according to the invention for carrying out analysis processes, with which m systems SY1 to SYm can be controlled simultaneously and independently of one another.
  • the individual systems SY1 to SYm are constructed similarly to the system described with reference to FIG. 1.
  • Each system SY1 to SYm consists of a valve arrangement V1 to Vm, each with n valves for the n feeds to the composition the mobile phase M.
  • the valve arrangement can be implemented, for example, by a so-called multiposition valve.
  • a valve arrangement V1 to Vm is connected to a corresponding reaction device S1 to Sm via a pump P1 to Pm.
  • control device ST An essential part of the arrangement is the control device ST. This takes over corresponding information, namely address and control information from a central control unit PR, which can be implemented by a microcomputer known per se. In the opposite direction, the control device ST transmits information, essentially reporting information, to the central control unit PR.
  • the control device ST has a modular structure and can therefore be adapted to different system configurations without any significant effort. The arrangement can thus be used both for carrying out analysis processes and for carrying out synthesis processes, preferably for a DNA synthesis or a peptide synthesis.
  • the control device ST has address evaluators AD1 to ADm in the form of address decoders for recording and evaluating the information to be transferred, that is to say in the incoming direction; Furthermore, the control device ST contains these function decoders FD1 to FDm which are connected to the individual systems SY1 to SYm, input memories ES1 to ESm and converter circuits U1 to Um. Encoders C1 to Cm and output memories AS1 to ASm assigned to the individual systems SY1 to SYm are present in the outgoing direction.
  • the connections between the individual units of the systems, ie between the valve assemblies, the pumps and the reactors and the units mentioned in the control device ST, are made via control and signaling lines SL and ML.
  • the individual functions Device B designed as a comparator may be present, to which the information stored in the input memories ES1 to ESm and in the output memories AS1 to ASm is supplied.
  • the information arriving via the common data path from the central control unit PR for example as 16-bit words, first reaches the address evaluators AD1 to ADm. Decoding takes place there and a corresponding selection criterion A1 to Am is formed. Subsequent control information is thus fed to the function decoders FD1 to FDm assigned to the selected system, decoded there and stored in the relevant input memory ES1 to ESm. In the assigned converter circuit U1 to Um, the control information is converted into a form suitable for controlling the individual units of the selected system.
  • the control criteria SK formed in this way reach the individual units of the selected system via the control lines SL. Such control criteria set one or more of the valves in the selected valve arrangement and thus the composition of the mobile phase.
  • Such a control criterion consists, for example, of a sequence of impulses.
  • Other control criteria switch the selected pump from external to internal control, set the flow rate of the relevant points and, if necessary, one or more pump valves.
  • the control criterion with which a pump is switched from internal to external control consists, for example, of a voltage signal.
  • the flow rate can be controlled by means of a rectangular pulse sequence of variable frequency.
  • Can be used to control a pump valve voltage signals of different amplitudes are used as control criteria.
  • Further control criteria are used to set certain sequence parameters, for example the temperature, in the selected reaction device.
  • Such a control criterion can be, for example, a signal of a certain voltage.
  • corresponding message criteria MK are available, which are issued by the individual units of the selected system and transferred to the relevant encoder via the message line ML.
  • the reporting criteria are also, for example, voltage signals of different amplitudes or pulse trains of variable frequency.
  • These reporting criteria MK are in turn converted into binary signals in the encoders C1 to Cm and stored in the relevant output memory AS1 to ASm. They are therefore available for a comparison with the information stored in a relevant input memory ES1 to ESm.
  • the central control unit PR can also be equipped with an additional memory, for example in the form of one or more floppy disks (so-called floppy disks), as a result of which the storage capacity for the operating conditions is significantly increased. It is also possible to use the central control unit PR in parallel with the control and monitoring of the systems for numerical evaluation or for the development of other operating conditions.
  • Control criteria SK reach the aggregates of a selected system via the control lines SL and queried reporting criteria MK are transferred from the aggregates to the control device ST via message lines ML.
  • the mobile phase M enters the reaction devices S1 to Sm via a first valve arrangement V31 with n * valves in the example, via a pump arrangement P31 and via a second valve arrangement V32 with a number of valves corresponding to the number of reaction devices.
  • a reaction device S1 to Sm is selected by the m valves of the second valve arrangement V32.
  • a third valve arrangement V33 whose m * valves are always actuated together with the valves of the second valve arrangement V32, is arranged downstream of the reaction devices S1 to Sm.
  • a further valve arrangement V34 enables the mobile phase to be directed into individual collecting containers ASl to ASl.
  • the target product e.g. an oligonucleotide is produced here in a reaction device, i.e. in a column Sl to Sm.
  • the corresponding valve in the valve arrangement V31 and the corresponding valves in the valve arrangements V32 and V33 are determined by means of corresponding control criteria SK formed by decoding the information transferred from the central control unit PR set.
  • the pump assembly P3 is switched to internal control if necessary, and the pump parameters are also set.
  • the reaction device S1 receives control criteria for setting the loading conditions for the current process or step are necessary. Reporting criteria are queried by the individual units as described via the reporting lines ML.
  • the mobile phase M is not continuously promoted. Rather, the reaction devices S1 to Sm are rather, so to speak, loaded, whereupon a reaction then takes place in the reaction devices. Since the loading time is considerably shorter than the reaction time, the pump arrangement P3 can operate a series of reaction devices in succession. This means that the synthesis processes are carried out in parallel in the m reaction devices. In practical operation, e.g. up to 16 oligonucleotides can be produced simultaneously.
  • reaction devices are each implemented as so-called individual columns.
  • reaction devices can be operated in a so-called column oven common to all reaction devices, the temperature of which can be set and regulated in the manner described by means of control and reporting criteria.
  • FIG. 4 shows one possibility of configuring a series of HPLC systems in a manner corresponding to the desired purposes of use.
  • two namely the systems designated SYA
  • two namely those designated SYS Systems intended for a synthesis process.
  • Both the analysis and the synthesis processes run under the control of the central control unit PR, which is provided only once, and also only once provided control section ST simultaneously.
  • the same external units reaction devices, pump and valve arrangements
