Organic Chemistry Analysis Services

Researching functional organic compounds, performing chemical analysis and evaluating their biological properties. 

  • The scientific group has a strong background in development and optimization of chromatography (both liquid and gas) and mass-spectrometry based analytical techniques and their applications in environmental, (bio) pharmaceutical and industrial objects; participates in R&D projects.
  • The main tasks are separation, identification and analysis of natural substances (mainly secondary metabolites, such as essential oils, flavonoids, polyphenols, coumarins, alkaloids etc.) with many different biological properties; bio-assays (toxicity, antimicrobial, antioxidant activity etc.) of the extracts, determination of the eco-toxic substances in different industrial matrices. 
  • Qualitative and quantitative determination of phthalates according to three standards: LST CEN ISO / TS 16181: 2011 (N), LST EN ISO 14389: 2014, NERI Reasearch Notes No 185 (N). Price 120 Eur + VAT. The price includes: sample preparation and qualitative / quantitative analysis. A 10% discount is applied for more than five samples.

The laboratory has extensive experience in dealing with cannabis extracts such as cannabidiol (CBD).

Organic Chemistry Analysis sample preparation techniques:

  • preparation of powder samples by a grinding-mill;
  • extraction with organic solvents,  solid-phase extraction, ultra-sonic agitation;
  • distillation, hydro-distillation by a Clevenger type apparatus;
  • pre-concentration procedure.
