Multi-Method Identification of Unknown Substances
OIKOS performs identification analyses of chemical substances of unknown composition or unestablished origin. Qualitative identification determines what compounds are present; quantitative identification provides concentrations and proportions. Non-routine analyses performed outside standard AB 934 accreditation scope — not intended for conformity assessment in regulated areas. Prior to accepting an order, OIKOS assesses analytical feasibility and informs the client of method limitations.
Why OIKOS for Chemical Identification
Four reasons our chemical identification stands out — non-routine analysis with transparent scope:
- Comprehensive analytical diagnostics: qualitative determination of chemical composition and quantitative determination of identified component concentrations
- Multi-method approach — GC, GC/MS, HPLC, UV/VIS and IR spectrophotometry, characteristic reactions — selected for the specific sample
- More than 35 years of analytical experience, including identification of environmental and industrial substances
- Transparent scope communication — clear indication of what results cover and what method limitations apply
GC, GC/MS, HPLC, UV/VIS, IR Spectrophotometry
The choice of analytical method depends on the sample characteristics and the analytical question posed:
Gas chromatography (GC) and GC/MS for volatile organic compounds and mixtures; HPLC for non-volatile and polar compounds; UV/VIS and IR spectrophotometry for functional group identification and concentration determination; characteristic chemical reactions as supplementary confirmatory tests.
OIKOS has operated as an analytical laboratory for more than 35 years, with broad methodological competence in instrumental analysis. Although identification analyses are performed outside the AB 934 accreditation scope, they are carried out by analytical personnel with documented qualifications and experience. Reliability is supported by independent verification through proficiency testing programmes organised under PT 010 accreditation.

FAQ
Chemical Identification Questions
What types of unknown substances can OIKOS identify?
OIKOS can identify liquid, gaseous, and solid substances of organic or inorganic chemical character, particularly mixtures of organic substances and environmental or industrial substances. Analytical feasibility is assessed individually for each enquiry before the order is accepted.
Are chemical identification results accredited?
No. Identification analyses are performed outside the AB 934 accreditation scope and do not carry accredited status. These results should not be used for conformity assessment in areas regulated by law.
What information is needed to request identification analysis?
Please provide: a sample description (state of matter, colour, odour, available quantity), probable or confirmed origin or application, the analytical question (qualitative, quantitative, or both), and any constraints on method or turnaround time.
Have a substance that needs identification?
