- the invention relates to an ion mobility spectrometer with such a drift tube and a method for producing such a drift tube
- Ion mobility spectrometers are known from the prior art which serve to detect chemical substances, warfare agents, explosives, drugs, etc. It is also known, for example, from DE 20 2013 105 685 U1 to use such ion mobility spectrometers in medicine, for example in the monitoring of narcosis during medical interventions. This is a

- ion mobility spectrometer no exact, repeatable and reliable Measurements of a proportion of an anesthetic in the respiratory air of a patient can be measured. Furthermore, it has been shown that, at first glance, apparently identical ion mobility spectrometers have output different measurement results for identical samples.
- Embodiments are subject of the dependent claims and / or explained below.
- the invention relates firstly to a drift tube made of, in particular, thermoplastic, plastic for use in an ion mobility spectrometer, which is used to monitor anesthesia of a patient during a medical procedure, comprising: an ionization chamber section in which molecules from to
- the drift tube is at one
- Inner wall of the ionization chamber section and / or the Driftcrobitess which radially defines a passage region of the air to be analyzed, aftertreated by means of a smoothing finishing process, whereby an adhesion of the present in the ppb region molecules of the anesthetic at
- Inner wall surface is at least greatly reduced, preferably completely prevented.
- ion mobility spectrometer according to the invention is a device to understand in which chemical substances, in particular molecules of
- analyzing breath are first ionized and then accelerated by an electric field to a detector and detected there.
- the ionization preferably generated by irradiation, takes place in one
- Drift chamber section / a drift space In the latter, the generated ionized particles drift against a gas flow. Particles / ions / molecules can both in the Drift frabites and in the ionisationscrobites with a
- the drift tube according to the invention can be seen as the above-mentioned component.
- the drift tube can only have one ionization chamber section, only one
- Drift chamber section has.
- the core of the present invention is that it has been found that a
- the inner wall surface of the drift tube is a central parameter in order to detect propofol in the respiratory air of a patient which is preferably used because of its pharmaceutical properties. According to the invention, it has been found that not the plastic material used for the drift tube allows use thereof in an ion mobility spectrometer as described above, but rather
- ion mobility spectrometer is crucial. It has been found that aftertreatment of the inner wall surface of the drift tube by means of a smoothing finishing process for the use of the drift tube in a
- ion mobility spectrometer is indispensable. An adhesion of the present in the ppb region molecules of the anesthetic, in particular propofol, is thereby greatly reduced or - as extensive series of experiments have shown - mostly completely prevented. Cleaning the ion mobility spectrometer is not necessary after every single measurement. Reliable, exact,
- At least one average roughness Rz of less than 2 ⁇ preferably an average roughness Rz of less than 1 ⁇ generated by the smoothing finishing process, creating a difference of peaks and valleys of the
- Inner wall surface is reduced so that a mechanical stopping or stopping the molecules of the anesthetic on their way through the drift tube through the tips of the inner wall surface is greatly reduced.
- the parameter of the averaged roughness Rz to a value less than 2 ⁇ , preferably less than 1 ⁇ , must be brought by the smoothing finishing process.
- the Rz value is determined in such a way that one measuring section is divided into five individual measuring sections, one
- the Rz value takes into account peaks and valleys of the surface responsible for mechanical sticking / stopping / stopping, thus better than others
- Roughness characteristics such as the average roughness Ra and thus according to the invention is the decisive parameter to be taken into account. It has been found that, if the Rz value is less than 2 ⁇ m, the tips of the inner wall surface have been removed such that stopping or arresting the molecules of
- Anesthetic is greatly reduced by the tips of the inner wall surface. Further, it has been found that when the Rz value is less than 1 ⁇ m, the tips of the inner wall surface have been removed such that stopping of the molecules of the anesthetic by the tips of the anesthetic
- the average roughness Rz of less than 2 ⁇ by
- polishing of the inner wall surface in particular has proven to be advantageous. Polishing generally creates a micro-roughness of a surface without activating the surface in any way and thus promoting specific adhesion of the molecules of the anesthetic.
- mechanical polishing by means of diamond has proved to be advantageous as a polishing agent.
- laser polishing has proved particularly advantageous for the application. In laser polishing, laser radiation is absorbed near the surface and the surface is smoothed by remelting (instead of material removal). Laser radiation is thereby by means of a
- Deflection unit steered onto the inner wall surface to be polished.
- polishing agents may be precluded during laser polishing.
- Inner wall surface is achieved and is prevented by the deformation, leveling and / or rounding of the tips of the inner wall surface, a mechanical stopping or stopping the molecules of the anesthetic on their way through the drift tube. It has been found according to the invention that an inner wall surface produced by mechanical polishing or laser polishing not only reduces a difference between peaks and valleys of the surface but also deforms, levels and rounds the peaks. This deformation / flattening / rounding of the tips prevents the anesthetic molecules from being stopped or stopped by the tips of the inner wall surface as they pass through the drift tube.
- drift tube is formed of a fluoroplastic, preferably polytetrafluoroethylene (PTFE) or perfluoroalkoxy (PFA), which is distinguished by antiadhesive properties.
- PTFE polytetrafluoroethylene
- PFA perfluoroalkoxy
- Thermoplastic fluoroplastics such as PTFE or PFA are characterized by their non-polarity, their anti-adhesive properties, as well as their mechanical and chemical resistance. They have an extremely low surface tension, and hardly any near-surface functional groups, whereby specific
- thermoplastic fluoroplastics PTFE and PFA lead to no / hardly any surface activation and thus reduced by the methods mentioned mechanical adhesion mechanisms due to the smoother surface / prevented and specific adhesion mechanisms are not reinforced / promoted by the selected pretreatment.
- the fluoroplastics used to make the drift tube is highly pure and virginal, that is unprocessed and unprocessed, not sintered and not recycled, not chemically modified and not provided with fillers, thereby providing even a marginal outgassing of volatiles containing a measurement result of the in ppb Region of the present molecule
- Fluoroplastic material PTFE or PFA
- the drift tube is made by machining, in particular by turning or milling, whereby a high manufacturing accuracy and reproducibility, a suitable functional integration and a variety of processing options can be achieved.
- machining the drift tube in particular a
- an Rz value of about 8 ⁇ is first realized, which is reduced by the smoothing finishing process according to the invention to less than 2 ⁇ .

- the drift tube 22 shown in FIG. 2 is made of a thermoplastic, preferably of a fluoroplastic, preferably of polytetrafluoroethylene (PTFE) or perfluoroalkoxy (PFA), and preferably produced by machining, in particular by turning, milling and / or drilling.

Since the present invention provides an ion mobility spectrometer which is intended to detect molecules of anesthetic (propofol) present in the ppb (parts per billion) range, a measurement result can be falsified even by only marginal outgassing of volatiles such as gases. It has been found according to the invention that only when highly pure, virginal plastic material is used, exact and repeatable
