Analytical Chemistry Expert Centre

Description of the group

The research group deals with the use of advanced measurement techniques to study the processes taking place in living organisms, physico-chemical processes taking place in historic objects and the qualitative and quantitative composition of clinical samples, pesticide residues in food, forensic traces, excavation objects, industrial products and semi-finished products. Access to modern equipment also enables scientific research aimed at understanding the processes of atomization, excitation and ionization in plasma, determining the distribution of elements on the surface and in subsurface layers of solid objects with high surface resolution and devoted to the characteristics of certified reference materials.

Scientific and research and implementation projects:

  • speciation analyzes of selected elements in samples with different matrix;
  • study of the influence of selected elements on the prevention of diseases;
  • proteomic and metabolomic analyzes of human, animal and plant tissues;
  • designing functional food;
  • food analysis for pesticide residues;
  • research of historic buildings;
  • studies of physical and chemical processes occurring on the surface of solids;
  • use of stable isotopes in understanding the origin of doping substances and the provenance of excavation objects;
  • studies of changes/durability of speciation forms during the preparation and storage of samples for analysis;
  • production, certification and use of matrix reference materials in ensuring the validity of chemical measurement results.

Research activity

Analytical Chemistry Expert Centre (ACE) cooperates with economic environment through organisation of scientific internships at CNBCh UW laboratories, for employees of enterprises from the region Mazowsze or supports enterprises with the experience and knowledge of our specialists. Cooperation with the industry is also carried out by conducting joint research and scientific projects or performing specialist contract works.

Analytical Chemistry Expert Centre is one of several laboratories of the University of Warsaw Biological and Chemical Research Centre which is accredited by the Polish Center for Accreditation (AB 1525).


The laboratory regularly participates in research confirming its competence in the field of research methodologies. In the last study for European reference laboratories organized by EURL European Union Reference Laboratory for Pesticide Residues, our laboratory received the highest category A (proficiency test for EUPT reference laboratories  round FV24) in the field of determination of plant protection product residues using the following techniques LC-MS/MS and GC -MS/MS.

Accredited services:

Analytical Chemistry Expert Centre is one of several laboratories of the University of Warsaw Biological and Chemical Research Centre which is accredited by the Polish Center for Accreditation (AB 1525). Experienced staff and appropriate equipment facilities ensure efficient execution of orders and validity of measurement results. The laboratory meets the system and technical requirements of the PN-EN ISO/IEC 17025:2018-02 standard “General requirements for the competence of testing and calibration laboratories”.

The accredited activities of ACE include:

  • testing pesticide residues in food and agricultural products using the HPLC-MS/MS and GC-MS/MS techniques (flexible scope of accreditation);
  • studies of dithiocarbamate residues in food and agricultural products GC-MS;
  • testing of mycotoxins in cereals, cereal products and food using the technique HPLC-MS/MS;
  • testing mycotoxins in animal feed using the technique HPLC-MS/MS;
  • testing the content of selected metals in food using the technique ICP-MS (flexible scope of accreditation);
  • testing the content of selected elements in water using the method ICP-MS.

Analytical Chemistry Expert Centre offers accredited tests of over 600 pesticides in food and agricultural products using the multi-compound method (so-called “multi”) using techniques LC-MS/MS and GC-MS/MS.

Our experts are constantly working on expanding this offer.

In addition, we specialize in demanding analyzes of polar pesticides using single methods using technique LC-MS/MS .

The identified compounds include, among others:

  • glyphosate and trimethylsulfonium cation;
  • ethephon;
  • fosetyl and phosphonic acid;
  • mepiquat and chlormequat;
  • chlorates and perchlorates;
  • bromide ion;
  • glufosinate with metabolites;
  • paraquat and diquat;
  • others.

Analytical Chemistry Expert Centre has a flexible scope of accreditation, which includes the analysis of pesticide residues using the technique LC-MS/MS and the analysis of metal residues in food using the technique ICP-MS.
