About Pyrolyscience

Pyrolyscience is a unique commercial laboratory & consultancy for analytical pyrolysis techniques such as pyrolysis-GC-MS (Py-GC-MS,Py-GC/MS).

This contract laboratory provides analytical and scientific services for the assessment of the molecular composition of natural organic matter by means of Py-GC-MS (conventional analytical pyrolysis) and THM-GC-MS (thermally assisted hydrolysis and methylation). Due to the complexities of pyrolytic reactions, good research in this field requires ample knowledge and experience. As a result these molecular tools are infra-utilized in many fields. Pyrolyscience focuses on providing that know-how, especially in the fields of the Earth and Heritage Science. By engaging in data evaluation up to the final phases of scientific research (publication in peer-reviewed  journals), clients can explore the realms of analytical pyrolysis without investing in equipment or training/hiring qualified personnel. In this sense, Pyrolyscience represents a different way of performing science not only in terms of methodology, but also in the nature of research collaboration through public–private partnerships (PPP). If done correctly, this kind of research is time- and cost-efficient. 


Pyrolyscience’s mission is to breathe fresh air into analytical pyrolysis applications, particularly in the fields of Earth Science and Heritage Science (in a wide sense: agronomy, archaeology, archaeometry, ecology, limnology, organic geochemistry, palaeoclimatology, petroleum science, soil science, etc.).

Pyrolyscience provides high-quality analysis and data evaluation in the field of analytical pyrolysis, in particular pyrolysis-gas chromatography-mass spectrometry (Py-GC-MS) and associated methods such as derivatization-Py-GC-MS (e.g. THM-GC-MS). Analytical pyrolysis is a rapid and straightforward approach to identification of organic polymers and mixtures thereof. These are cleaved by thermal energy in inert gas (pyrolysis) and their products separated by GC and identified by means of MS. Especially in complex samples such analysis allows for a rapid screening of virtually all the organic constituents present in a sample.

Pyrolyscience has experience with the characterization of diverse environments and materials such as soil organic matter (SOM) from soils around the world (drylands, permafrost, paddy fields, colluvial soils, tropical soils, etc.), lacustrine sediments, speleothems, dissolved organic matter (DOM), Blue Carbon ecosystems (coastal plants, seagrass sediments, mangrove sediments, tidal marsh), Black Carbon materials (anthropogenic dark earths, charcoal, biochar, urban dust, ceramics), geological materials (coal, kerogen, amber) and diverse archaeological and historical samples (a.o. paintings, bones, mummies, jewels) (Applications).

Pyrolyscience has active partnerships with the Institute of Agrarian Sciences (ICA-CSIC, Madrid, Spain), Institute of Heritage Sciences (Incipit-CSIC, Santiago de Compostela, Spain), ECOPAST (Universidade de Santiago de Compostela, Spain), NOMLAB (Southwest University, Chongqing, China) and Lablicate GmbH (Hamburg, Germany).


Joeri Kaal


Joeri Kaal finished his MSc. in Earth Sciences at IBED of University of Amsterdam studying tannin adsorption by synthetic soils. He completed his PhD research on the fire history of Galicia in 2011 – using molecular (Py-GC-MS, NMR), pollen (palynology) and charcoal (anthracology) records – at the University of Santiago de Compostela and the Institute of Heritage Sciences (Incipit, CSIC). Since then, he worked as an independent scientist performing palaeoecological and analytical pyrolysis research. Working at both the soil science department of the University of Santiago de Compostela and the Incipit, being responsible of an organic chemistry lab, allowed him to work with a large variety of organic materials from Earth and Heritage science, gaining experience and versatility. In 2018, he launched Pyrolyscience. Joeri’s publication record can be found on Google Scholar, Researchgate, Orcid or Scopus.

Dr. César Plaza de Carlos

Member of the Scientific Advisory Board

César Plaza graduated in Chemistry in 1998 and completed his PhD in 2002 at the Universidad Autónoma de Madrid (Spain). At the Institute of Agrarian Sciences (ICA-CSIC, Madrid), César leads the Sustainable Agriculture and Biogeochemistry research group. His research focuses on mechanisms of soil organic matter stabilization and C sequestration, in addition to organic waste amendment strategies in agriculture (composting, pyrolysis, etc.). He has a particular interest in SOM dynamics in dryland ecosystems. César (co-)authored more than 100 publications (Orcid). César has served as Chair of the Soil Chemistry Subdivision of the European Geosciences Union (2016-2018) and is a Member of the Spanish Ministry of Agriculture Expert Group on Fertilization (2020-).

Dr. Ir. Klaas G.J. NIerop

Member of the Scientific Advisory Board

Klaas Nierop studied Chemical Technology with specialisation in organic chemistry at Twente University. After obtaining his PhD at Wageningen University on organic matter in incipient podzols he worked as a postdoctoral fellow at the University of Amsterdam on soil (organic matter) chemistry, meanwhile meeting Joeri. Moving to Utrecht University (UU) he changed from terrestrial to marine geochemistry and currently works as an analytical (geo)chemist at the organic geochemical and stable isotope labs of the GeoLab. He functions as the interface between scientists, technicians and students, which he advises on analytical and organic chemical techniques. He is Associate Editor of Organic Geochemistry and has published 100 papers in internationally refereed journals. Klaas is a renowned expert in the field of analytical pyrolysis. He has unparalleled knowledge on aliphatic and phenolic macromolecules in soils and sediments and their characterization using analytical pyrolysis. Research interest include analytical development and application of biomarkers (both extractable lipids and biopolymers) to trace (past) environmental conditions.
