Definitions
- the invention relates to a laboratory device according to the preamble of claim 1.
- a generic laboratory device may e.g. a device for performing nucleic acid amplification method (hereinafter referred to as PCR reactions) in which the quantitative formation of the amplification products (PCR products) during the PCR reactions is measured optically.
- PCR reactions nucleic acid amplification method
- This special form of PCR is called a real-time PCR reaction.
- PCR devices are discussed, without any limitation being thereby intended.
- sample mixtures are usually measured which contain fluorescent indicators for optical measurement purposes; which, upon excitation with light of a suitable wavelength, emit fluorescence signals whose intensity is dependent on the amount of PCR product formed.
- fluorescent indicators for optical measurement purposes; which, upon excitation with light of a suitable wavelength, emit fluorescence signals whose intensity is dependent on the amount of PCR product formed.
- the increase in PCR products can be monitored by an increase in the intensity of the measured fluorescence signals.
- measurements in transmission are also conceivable.
- the plurality of samples simultaneously processed in such generic laboratory devices are usually arranged in an array.
- a thermocycler brings the samples e.g. to the various PCR temperature levels, e.g. with a temperature gradient in one or more of the stages.
- the generic laboratory device has an illumination device that emits light of suitable wavelength to the samples. It may be with this light source, e.g. to act as a blue or white LED, other alternatives are e.g. Halogen lamps, xenon lamps, laser diodes, lasers, etc. Further, additional optical imaging components may be provided to illuminate the illumination light, e.g. to filter or to map to the samples.
- a detector which generates measured values as a function of a measured light intensity. It can also be provided more than one detector.
- the detector may e.g. a CCD chip or a photomultiplier or a CCD chip or a photomultiplier included.
- the light intensity usually increases with the number of PCR products. But there are also known methods in which a decrease in fluorescence, the increase of the PCR products is observed.
- the device furthermore generally has optical devices which emit a beam path from the illumination device to the reaction samples and from there to define the detector.
- optical devices include, for example, a dichroic mirror arranged between the illumination device and samples, which allows the excitation light emanating from the illumination device to pass to the samples and reflects a long-wave fluorescence signal emitted from the optically excited reaction samples onto the eg laterally arranged detector.
- a number of other optical components are provided, for example filters upstream of the detector, lenses, etc.
- fluorescence or change in fluorescence will not be observable in all samples. If the starting product to be amplified by PCR is e.g. not included in the sample, no fluorescence will be observed. However, it is indistinguishable in such samples, whether the absence of fluorescence really comes from the absence of the starting product, or possibly the excitation light source is defective, so the fluorescence was not excited. Both lead to the same result. It would be eminently important to be able to clearly determine why fluorescence is not observed, since real-time PCR measurements are e.g. used in medical diagnostics. False diagnoses could have fatal consequences.
- a generic device which has a monitoring device that can monitor the function of the lighting device.
- This monitoring device consists of an additional light detector, which is arranged so that it is acted upon by the illumination light source with illumination light.

A monitoring of the light-emitting diodes for proper function does not take place, so that no clear statement about the cause is feasible in the absence of fluorescence.
- the object of the invention is, starting from the prior art, to provide a laboratory device with a simple and reliable monitoring of the function of the illumination device.
- the illumination device consists of a plurality of light-emitting diodes each assigned to a single one of the plurality of samples, wherein, for example, according to claim 2, advantageously only one of the light-emitting diodes is currently switched off. Radiation is controlled by illumination light.
- the monitoring device has no optical but electrical devices with which an electricalnossübe ⁇ riifung of the LEDs is executable, wherein the monitoring device is further configured to generate a signal upon detection of a malfunction of a light emitting diode.
- the term light-emitting diodes should also encompass laser diodes.
- an electrical function monitoring can be carried out with simple means, to implement a variety of alternative possibilities exist. It could e.g. at each of the light emitting diodes, whether e.g. a current flows through the diode or as e.g. the voltage across the diode behaves. It could also be monitored the device supplying power to the LED according to their electrical properties.
- the laboratory device may continue to be e.g. according to claim 7 advantageously have a thermal cycler, which can be controlled by a control device for controlling the temperature of the plurality of samples to specific reaction temperatures.
- the termocycler can advantageously be used e.g. be driven according to claim 9 for generating a temperature gradient.
- the laboratory device according to the invention can furthermore be designed advantageously according to claim 8 for carrying out real-time PCR reactions.
- the monitoring device advantageously has comparators for comparing the measured output voltage with a predetermined output voltage range.
- the signal of the monitoring device can indicate in the simplest embodiment that a malfunction of the illumination device has been determined without identifying the defective LED in more detail. With such limited information, all measurement results would potentially be error-prone and therefore basically discard. In view of the fact that but for all the trouble-free working LEDs attributable samples usable results, a complete rejection of all results a waste of the used, usually costly samples and the time spent.
- the monitoring device according to claim 6 therefore Generation of the dysfunctional LED identifying signal formed. This information is then immediately available, for example, if a function monitoring takes place locally on each of the LEDs.
- a decentralized function monitoring for example, by monitoring the DC power source, but this information can also be easily obtained, for example by evaluating the information which LED has been driven when lighting and when the malfunction was detected, or eg by the light emitting diodes controlling switch Detecting the fault.
- This evaluation can be done, for example, in an evaluation and control device that contains both the control intelligence for the control of the laboratory device, as well as the Ausenseintelligenz to receive the measurement signals from the detector to record and evaluate. It can then be used in identifying the malfunctioning LED then advantageously all measurements in which no interference has occurred, while selectively that measurement can be discarded, in which the illumination diode has shown a malfunction.
- the laboratory device may e.g. according to claim 10, having a display on which the unusable position is displayed to the user, e.g. by displaying the faulty LED or by displaying the corresponding sample slot in the array.
- the laboratory device can thus continue to be used with this restriction; not until replacement of the defective LED e.g. to be serviced by a service technician.
- the consideration of a light-emitting diode identified as faulty can e.g. even with Neukalibaration of the device done or when calibrating the device to a new dye. It can e.g. the measurement result to be assigned to this light-emitting diode is excluded in averaging.
- the device 10 has a schematically illustrated conventional thermal cycler 11 with receptacles 12 for receiving a plurality of samples.
- 12 reaction vessels not shown, are used in the recordings, in each of which a PCR approach is included with a fluorescence indicator.
- a cover housing 13 is mounted with a lighting device with a plurality of light-emitting diodes 14.
- the light-emitting diodes 14 are arrayed, as are the receptacles 12. In the measurement, the light-emitting diodes 14 are preferably switched on and off individually by the control and evaluation device 50 so that only one assigned receptacle 12 is irradiated at a time.
- An exemplary light path from a light emitting diode 14 to a detector 27 is shown at 15, 15 '.
- the light 15 is emitted from the light emitting diode 14, and then may be e.g. pass a short-pass filter 16, not shown, are filtered out with the long-wave components.
- the light 15 can be focused on the associated receptacle 12 by a lens array, also not shown.
- the excitation light 15 passes through a beam splitter 17, which is preferably completely permeable in this direction.
- a dichroic mirror is used as the beam splitter 17, which passes excitation light 15 with high efficiency, but reflects the emitted longer-wavelength fluorescence signal 15 'with high efficiency.
- the light 15 emitted by the light-emitting diode 14 is intended to excite a fluorescence indicator located in the receptacle 12 in a PCR approach. It must have a suitable wavelength to stimulate the fluorescence can.
- the fluorescent indicator Upon excitation, the fluorescent indicator emits a fluorescence signal 15 '.
- the beam splitter 17 is designed such that the fluorescent signal 15 'impinging on it is reflected to the side.
- the optical arrangement shown thus corresponds to a typical 90 ° measurement arrangement for fluorescence measurements.
- the reflected fluorescence signal 15 'then passes to a detector 27 which detects the fluorescence intensity.
- the detector 27 is preceded by various optical devices with which the fluorescence signal 15 'can be imaged onto the detector 27.
- the optical devices comprise a plurality of optical fibers 20 with light entry surfaces 21, each associated with a receptacle 12 or the fluorescence signals 15 'emitted from the receptacles 12 and reflected at the beam splitter 17.
- the light entry surfaces 21 are preferably in turn arranged like the light emitting diodes 14 and the receptacles 12 in an array.
- the optical fibers 20 are combined at its outlet end into a bundle 23.
- the bundling ensures that the fluorescence signals from all the receptacles 12 emerge relatively close together from the exit ends of the respective fibers, namely in the vicinity of the optical axis 28 of the detector 27.
- a narrowly defined exit surface is preferred in order to collimate the exiting fluorescent light beams. their propagation directions differ only slightly from optical fiber to optical fiber. This is particularly advantageous if the filter following the outlet end are interference filters whose spectral transmission characteristics are dependent on the angle of incidence on the filters.
- the fluorescence signal 15 is then imaged by the optical fiber bundle 23 on the detector 27 via further optical devices, eg a lens 24, a bandpass filter 25 and a further lens 26.
- the filters may also be automatically interchangeable to adapt the device to different fluorescent indicators.
- the LEDs 14 are all connected in parallel to a DC power source 30, which consists essentially of a supply voltage source 32, such as a power supply, which is current-stabilized with a conventional electronic circuit 34, for example, a negative feedback transistor. Other supply voltage sources and other electronic circuits for current stabilization are also possible.
- each of the light-emitting diodes 14 is dominated by a respective associated switch 39, 40, which can assume a closed and an open position.
- the plurality of switches 39, 40 which are combined to form a switch unit 38, are closed or opened by the control and evaluation device 50 with control signals. In the example shown switch 39 is closed and switch 40 is open.
- each individual light-emitting diode 14 can be realized in a preferred manner by switches which control all light-emitting diodes of a column or all light-emitting diodes of a row. Closing a column switch and a return switch energizes the LED that is in both the selected column and the selected row.
- a monitoring device 45 monitors the output voltage of the light emitting diodes 14 supplied with power constant current source 30. It can be observed that when current flows through a functioning light emitting diode, the output voltage drops. This voltage drop is substantially the same for all when using the same light-emitting diodes. For example, considering aging and drift effects, a voltage range may be defined in which the measured output voltage should be when a functioning light emitting diode is energized.
- the monitoring device 45 is com communicating with the control and evaluation device 50 connected. In the illustrated embodiment, the monitoring device 45 receives control signals when one of the LEDs 14 is turned on. It then measures the output voltage and compares the measured voltage with a voltage range defined as permissible.
- an error message is sent via the signal line 47 to the control and evaluation device 50, which determines from the temporal occurrence of the error signal or, for example, from the positions of the switches 39, 40, which light-emitting diode 14 causes a faulty output voltage and therefore classified as dysfunctional.
- the control and evaluation device 50 determines from the temporal occurrence of the error signal or, for example, from the positions of the switches 39, 40, which light-emitting diode 14 causes a faulty output voltage and therefore classified as dysfunctional.
- the results which originate from the sample which is to be assigned to the functionally faulty light-emitting diode 24 are not taken into account or indicated as being faulty.
- the dysfunctional LED 14 may be displayed on a display device 55 with an indication that the correspondingly assigned recording should not be used. This error message is eliminated as soon as the malfunctioning LED 14 is replaced.
- the error message can graphically indicate the sample location in the array associated with the failed light emitting diode 14, and thus can not be used. Also, a
