TY - CONF A1 - Meyer, Klas T1 - BAM quality toolbox framework for qNMR N2 - Accreditation of analytical methods, either according to GxP or ISO regulations, requires a comprehensive quality management system. General quality documents are often already in place, which need to be extended by method-specific documentation. In this presentation we like to show an idea of a modular set of standard operating procedures (SOP) specifically developed meeting the requirements for quantitative NMR. The future goal is to collaborate with different accreditated NMR laboratories to compile a universal set of SOP and other quality documents that can be modified and used as a starting point for developing your own quality system for applications of qNMR in a regulated environment.

It is the basis for accreditation by an accreditation body. The current version was published in 2018. Implementing ISO/IEC 17025 as part of laboratory quality initiatives offers both laboratory and business benefits, such as expanding the potential customer base for testing and/or calibration, increasing the reputation and image of the laboratory at national and international level, continuous improvement of the data quality and the effectiveness of the laboratory or creation of a good basis for most other quality systems in the laboratory sector, such as GxP. The main difference between a proper approach to analysis and a formal accreditation is shown in a targeted documentation, especially on the qualification of the personnel, the test equipment and the validation of the analytical methods. Using quantitative NMR spectroscopy as an example, it is shown how accreditation can be carried out and what documentation is required. In our case, we have described the procedure in an SOP ("Determination of the quantitative composition of simple mixtures of structurally known compounds with 1H-NMR spectroscopy") and supported it with a modular system of organizational and equipment SOPs. The special feature is that the accredited method is independent for the choice of the analyte and the matrix and therefore it is possible to operate with a single validated method. In our case, we have proposed three quality levels ("leagues") with different levels of analytical effort, which differ in their measurement uncertainty, in order to simplify the workflow and analysis design.

The potential of digital technologies belongs to these. Flexible and modular chemical plants can produce various high-quality products using multi-purpose equipment with short downtimes between campaigns and reduce time to market for new products. Intensified continuous production plants allow for difficult to produce compounds. Therefore, fully automated “chemical” process control along with real-time quality control are prerequisites to such concepts and thus should be based on “chemical” information. The advances of a fully automated NMR sensor were exploited, using a given pharmaceutical lithiation reaction as an example process within a modular pilot plant. A commercially available benchtop NMR spectrometer was integrated to the full requirements of an automated chemical production environment such as, e.g., explosion safety, field communication, and robust evaluation of sensor data. It was thereof used for direct loop advanced process control and real-time optimization of the process. NMR appeared as preeminent online analytical tool and allowed using a modular data analysis tool, which even served as reliable reference method for further PAT applications. In future, such fully integrated and intelligently interconnecting “smart” systems and processes can speed up the high-quality production of specialty chemicals and pharmaceuticals.

Zunächst stark fokussiert auf den Forschungs-bereich, sind sie heute zunehmend auch nahe der Produktion auf dem Vormarsch. Die Zielstellung ist nur selten der Ersatz von klassischer „Hochfeld“-NMR-Spektroskopie. Vielmehr erschließen die kompakten Geräte oftmals neue Anwendungsfelder, beispielsweise in der Online-Reaktionsverfolgung im Labor oder der schnellen at-line Qualitätskontrolle in der chemischen Produktion. Hier kommen die Vorteile der geringeren Anschaffungs- und Betriebskosten, die Möglichkeit des prozessnahen Einsatzes, sowie besonders der einfachen Bedienung zum Tragen. Während es zahlreiche Beispiele von Online-Applikationen im Labor gibt, ist die direkte Einbindung in großtechnische Produktionsanlagen bislang selten. Im Vergleich zu etablierten prozessanalytischen Verfahren, wie z.B. der Nahinfrarot- oder Raman-Spektroskopie ist die Benchtop-NMR-Spektroskopie noch Neuland und es existieren kaum prozesstaugliche kommerzielle Lösungen. Im Rahmen eines gemeinsamen Entwicklungsprojekts zwischen BAM und Evonik wurde eine Einhausung für ein handelsübliches Benchtop-NMR-Spektrometer konzipiert und gebaut. Diese dient nicht nur der Erfüllung sicherheitstechnischer Auflagen wie dem Explosionsschutz, sondern auch der Abschirmung rauer Umgebungseinflüsse auf den Betrieb des Laborgeräts. Eine flexible integrierte Automatisierung ermöglicht die skalierbare Anbindung an übergeordnete Prozessleittechnik im Sinne eines PAT-Moduls. Dieser Vortrag gibt einen Überblick über die Herausforderungen auf dem Weg von der Idee, über die Umsetzung bis hin zur tatsächlichen Prozessintegration. T2 - 47.
