Accredited Sample Analysis for Other Laboratories
OIKOS accepts samples for analysis delivered by other laboratories: air on filters (dust, metals, Cr6+), in absorption solutions, on sorbent tubes (organic substances, formaldehyde), indoor and atmospheric air samples, and stack gas samples. All analyses are performed within the scope of PCA accreditation No. AB 934 (PN-EN ISO/IEC 17025). The ordering laboratory receives results in a test report bearing the accreditation symbol, allowing direct use in conformity assessment procedures and legally regulated areas.
Why OIKOS for Subcontracted Sample Analysis
Five reasons our subcontracted sample analysis stands out — accredited results that fit straight into your test report:
- Results carry full AB 934 accredited status — ready to be incorporated into your test report and accepted in legally regulated areas
- Formal chain of custody compliant with clause 6.6 of PN-EN ISO/IEC 17025:2018 — subcontracting does not compromise the integrity of your accreditation
- Broad analytical scope: filters (dust, metals, Cr6+), absorption solutions, sorbent tubes (organic substances, formaldehyde), stack gases
- More than 35 years of experience in workplace and atmospheric air analysis — methodological reliability
- PT programme organiser (PT 010 accreditation) — analytical competence independently confirmed, not merely declared
Filters, Absorption Solutions, Sorbent Tubes
OIKOS accepts samples in a wide range of matrices: filters (particulate matter, heavy metals, hexavalent chromium Cr6+), absorption solutions (chemical substances analysed by spectrophotometric and chromatographic methods), sorbent tubes (organic substances, formaldehyde), and stack gas samples.
The sample intake procedure incorporates a formal chain of custody: delivery documentation, sample integrity verification, matrix identity confirmation, and storage conditions required for individual analytes. The ordering laboratory may specify its own turnaround time requirements.

FAQ
Sample Submission Questions
Do results issued by OIKOS carry accredited status?
Yes. Analyses performed within AB 934 scope are documented in a test report bearing the PCA accreditation symbol. Results may be used by the ordering laboratory in legally regulated areas.
What is the sample delivery procedure?
Samples should be delivered to OIKOS premises in Święta Katarzyna near Wrocław, accompanied by documentation identifying the sample, matrix, analyte, and storage conditions. Detailed requirements will be communicated after the order scope is confirmed.
How does OIKOS manage chain of custody for samples delivered by other laboratories?
OIKOS applies a documented sample intake procedure covering delivery registration, integrity verification, identification, and storage under conditions required for the given matrix. This procedure forms part of the accredited laboratory management system and meets the requirements of PN-EN ISO/IEC 17025.
Which analytes can OIKOS determine in stack gas samples delivered by another laboratory?
For stack gases, OIKOS analyses samples collected in absorption solutions and on sorbents, in accordance with the AB 934 accreditation scope. A full list of analytes is available on the Laboratory Documents page.
