Physikalisch-Technische Bundesanstalt (PTB)
Christine Brauckmann, born in 1985, studied chemistry at the Westfälischen Wilhelms-Universität Münster and received her diploma degree there. In 2012, she completed her PhD in analytical chemistry with its focus on speciation analysis and started working at the Physikalisch-Technische Bundesanstalt (PTB) in the same year. Since 2018, she has been responsible for the measurement and organization of one of the first CCQM intercomparison of a metalloprotein in clinical matrix.
Leitmotif
„Thinking Without a Banister“ (Hannah Arendt)
Activities
Christine Brauckmann organizes and performs the measurements in comparisons of the Consultative Committee for Amount of Substance – Metrology in Chemistry and Biology (CCQM) for proteins. These CCQM comparisons assure the traceability of peptide and protein reference materials and measurement procedures at the highest international level of metrology. With such interlaboratory comparisons the international metrology institutes (NMIs) can prove their measurement capabilities. Additionally, she is a member of the Gesellschaft Deutscher Chemiker (GDCh).
Awards
Poster award at the Metallomics 2009 in Cincinnati, as well as poster award at the Protein and Peptide Therapeutics and Diagnostics: Research and Quality Assurance International Workshop 2016 in Chengdu, China.
Focus
The focus of Christine Brauckmann is the development and validation of SI traceable methods for clinical biomarkers as well as the characterization of reference material for SI traceable methods.

World Metrology Day is celebrated annually on the 20th of May and this year’s focus on health provides an opportunity to emphasize the importance of comparable and reliable measurement (…)
Scientists from the Physikalisch-Technische Bundesanstalt (PTB) have implemented a novel pressure measurement method, quasi as a byproduct of the work on the "new" kelvin. In addition to being new, this procedure is a primary method, i.e. it only depends on natural constants. As an independ ... more
Don't Give the Slightest Chance to Toxic Elements in Medicinal Products
Lead, cadmium, mercury, and arsenic do not belong in medicinal products. International requirements for the quality of medicines have therefore become more stringent and introduced new control requirements. Hence, it makes sense to use high-accuracy reference solutions with defined contents ... more
Measurement of the dynamic mechanical properties of viscous materials
In microsystems metallic components are increasingly being replaced by those from low-cost polymers. For the thickness measurement of polymers, there is now the DIN standard 32567 available, which describes both, optical and tactile surface measuring methods for the precise measurement of t ... more

How the Avogadro constant was measured for the last time
Since the 20th of May 2019, the mass unit kilogram is no longer defined by the international kilogram prototype but by the numerical value of the Planck constant, the most important fundamental constant in quantum physics. For this definition, the Planck constant needed to be measured with ... more
Natural constants take center stage
The 20th of May 2019 is a special day. From that day on, the old definitions of what a kilogram, a mole, an ampere and a kelvin represent, are history. The future of the International System of Units will see natural constants play the star roles. more
Gavin O’Connor was born in Dublin and completed a Diploma in analytical chemistry at Athlone Institute of Technology, Ireland, in 1993. He continued his studies in analytical chemistry to B.Sc. level in the UK before completing his PhD in mass spectrometry at the University of Plymouth in 1 ... more
André Henrion, born in 1957, studied chemistry at Humboldt-University in Berlin, where he received his doctorate in 1988 in the field of Physical Organic Chemistry. After working at the Academy of Sciences in Berlin for a short period he moved on to the Physikalisch-Technische Bundesanstalt ... more
Rüdiger Ohlendorf, born in 1959, studied chemical engineering with a focus on instrumental analysis at the Münster University of Applied Sciences. After working at ISAS (Institute for Spectrochemistry and Applied Spectroscopy) and at Schering AG, he moved on to the Physikalisch-Technische B ... more
