Definitions
- the invention relates to a device for identifying biotic particles in a gaseous or liquid medium.
- Ambient air are known and continue to be the subject of current research.
- the goal of research and development is to make the detection methods for biotic particles more selective, reliable and faster, and correspondingly reliable and compact devices for the automated identification of biotic particles
- a clean room is a room in which the concentration of airborne abiotic particles (eg dusts) and biotic particles (microorganisms such as:
- Bacteria, fungi, algae, protozoa, viruses is kept as low as possible.
- the clean room conditions to be met will depend on the application or
- Identification of the biotic particles is preferably carried out by the use of Raman spectroscopy [eg. Raman, FT-Raman, NIR-FT-Raman, Resonance Raman, UV Resonance Raman, SERS (Surface Enhanced Raman Spectroscopy), SERRS (Engl., Surface Enhanced Resonance Raman Spectroscopy)).
- Raman spectroscopy eg. Raman, FT-Raman, NIR-FT-Raman, Resonance Raman, UV Resonance Raman, SERS (Surface Enhanced Raman Spectroscopy), SERRS (Engl., Surface Enhanced Resonance Raman Spectroscopy)
- the document DE 10 2004 008 762 B4 discloses such a method and device for detecting and identifying biotic particles (bioparticles).
- the device described comprises a filter on which biotic and abiotic particles are deposited, for example, from an air stream
- the device further comprises a detection unit for determining the position and shape factors of individual biotic particles deposited on the filter and differentiating between biotic and abiotic particles.
- the device finally comprises an identification device, with which Raman spectra of the deposited particles can be determined, and a
- Identification of the detected particles can be further processed.
- the object of the invention is to provide a device which allows a reliable and rapid identification of biotic particles in a medium, compared to the prior art reduces the maintenance and the
- the object is achieved by a device for identifying biotic particles in a medium to be examined, with a flow-through from the medium to be examined measuring cell in the identification of the biotic particles by Raman spectroscopy, and a feed, by means of which the medium to be examined Measuring cell can be supplied, wherein the supply comprises at least one sensor with which the presence of biotic particles in the feed medium can be determined, the supply downstream of the sensor has a controllable bypass valve, via which the medium optionally the measuring cell or a bypass -Canal is supplied, and a first control means is provided, by means of which the bypass valve is controlled such that the medium is supplied to the measuring cell for the identification of the biotic particles only if biotic particles were detected by the sensor in the medium.
- the device according to the invention is based on the idea of supplying the medium to be investigated (gaseous or liquid) to the measuring cell only if it differs from that in the Supply arranged sensor, the presence of biotic particles was detected in the feed medium flowing through. If, on the other hand, no biotic particles in the medium to be examined are detected by the sensor, the medium is fed to a bypass channel instead of the measuring cell, through which the medium, for example, enters the environment. The corresponding switching of the media flow is effected by the bypass valve upstream of the measuring cell, which is controlled by the first control means.
- the bypass valve is preferably configured in such a way that the switching time between the two valve states (forwarding of the entire media flow to the measuring cell or to the bypass channel) is as low as possible, so that ideally the media flow can be digitally transmitted either to the measuring cell or to the bypass. Channel is supplied.
- a “bypass valve” is understood here to mean a device having an input channel E and two output channels A1 and A2, wherein the medium to be examined flowing through the input channel E flows out selectively, ie switchable, either through the output channel A1 or through the output channel A2.
- one output channel of the bypass valve is connected to the measuring cell and the other output channel to the bypass channel
- Such a bypass valve can be produced, for example, using methods of microsystem technology, whereby the switching of the output channels takes place by means of microactuators
- a plurality of inventively designed feeds can be arranged in parallel and connected to the measuring cell.
- bypass channel is understood broadly in the present case, which may be a pipeline, a flow or a discharge opening.
- the term "presence” is synonymous with “presence” or “presence.”
- the sensor used is preferably an optical sensor with which at least one optical property of the medium to be examined, such as the
- Fluorescence, or absorption or transmission property can be determined.
- the sensor is calibrated accordingly, so that the presence of biotic particles is detected sufficiently clearly.
- the sensor preferably evaluates more than one optical property or it is also possible to use a plurality of sensors which detect optical or other properties of the medium to be examined.
- a preferred embodiment of the device according to the invention is characterized in that the one or another sensor is an optical sensor with which a particle size and / or a particle density in the medium to be examined particles can be determined. This allows, for example, a distinction of abiotic and biotic particles.
- the sensor is furthermore preferably configured and configured such that it detects the entire flow cross-section of the medium flowing through the feed. This ensures that all biotic particles present in the medium can be detected by the sensor.
- the evaluation of the sensor signals must, depending on the flow rate of the medium through the supply, take place sufficiently fast, so that the control means switches the bypass valve downstream of the sensor before a volume of media sensed by the sensor reaches the bypass valve.
- the time required for the evaluation of the sensor measurement and the switching time delay of the bypass valve timely switching of the bypass valve can be ensured so that the medium to be examined only enters the measuring cell, if biotic particles are present in the medium to be examined.
- the supply between the bypass valve and the measuring cell or the measuring cell itself has a first means with which biotic particles contained in the medium to be examined can be deactivated.
- activation in the present case also means “kill” or “render harmless”.
- Inactivation in particular harmful germs can be killed.
- the inactivation can generally be used, even if germs that are harmful to health can not be expected in order to generally work with inactive biotic particles when evaluating the Raman spectra obtained in the measuring cell. This has the Advantage that in the evaluation of the spectra for the identification of individual biotic particles do not parallel several reference databases, ie for biotic active particles and biotic inactive particles must be used.
- the first means for inactivating biotic particles preferably has at least one electromagnetic and / or one acoustic radiation source and / or one
- the first means may be designed and arranged to deliver a biotic particle inactivating substance into the medium to be examined.
- Corresponding substances, electromagnetic, acoustic or particle radiation sources are known to the person skilled in the art.
- the measuring cell further comprises at least one sensor means with which the shape, and / or the size, and / or the surface condition, and / or the color and / or elastic scattered light data of one or more biotic particles can be detected.
- sensor data can, for example, be evaluated by means of pattern recognition methods and facilitate or enable differentiation of abiotic and biotic particles.
- the acquired different measurement data can be correlated with each other, which enables an improved classification or identification of the biotic particles.
- a further preferred development of the device according to the invention is characterized in that the measuring cell has a filter on which biotic particles can be deposited for identification by means of Raman spectroscopy.

- the continuous pore channels thus taper from the front of the filter to the back of the filter.
- the capture molecules can, for example, specifically retain a certain type of biotic particles, for example bacteria.

- the filter should continue to provide only a low and / or a constant Raman background signal.
- Suitable filters are micromechanical filters with a filter thickness in the range of 400 nm - 10 pm, for example, of silicon, metal, quartz, with metal-coated material.
