Dr. Petra Krystek













Dr. Petra Krystek gained her PhD in analytical chemistry, and she has more than 25 years of experience within this field; especially in method development with inductively coupled plasma mass spectrometry (ICPMS) and instrumental hyphenations with various separation techniques (e.g. GC, LC and AF4). Her research is strongly application focused, regarding to ultra-trace, speciation and nano-analysis (incl. micro-/nano-plastics) but also sampling and sample pre-treatment strategies. The (scientific) quality assurance is very crucial for her, and she has fulfilled international roles as lead and technical assessor regarding to laboratory quality management systems (ISO/IEC 17025). Dr. Petra Krystek has worked at research institutes as well as in industries in Germany and the Netherlands. Her research is characterized by its embedding in a broad international network consisting of outstanding research groups, while she has been leading many interdisciplinary research projects about anthropogenic substances and possible impact and effects to health, environment (focus: water – soil), and sustainability
