Lab accreditation & certificates
Chemyo’s commitment to purity and accuracy is not a marketing claim — it is a testable, verifiable standard. This page explains who tests our products, what accreditation means, and how to access the Certificate of Analysis for your specific batch.
Independent third-party testing
Every Chemyo product batch is sent to an independent, accredited analytical laboratory for testing before it is made available for sale. We do not rely on manufacturer-provided certificates, in-house testing, or batch-representative sampling. Each distinct batch is tested individually.
The laboratories we work with are completely independent from Chemyo — they have no commercial interest in the results they produce. That separation is the only way to provide genuinely objective assurance of product quality, which is why it sits at the centre of our quality-control process.
Why an independent ISO/IEC 17025 lab matters
An accreditation standard exists so that a test result carries weight beyond the lab that produced it. ISO/IEC 17025 is that standard for testing and calibration laboratories.
A recognised competence standard
ISO/IEC 17025 is the international standard for the competence of testing and calibration laboratories. It governs quality management, method validation, equipment calibration, personnel qualification, and data integrity.
Assessed, not self-declared
Accreditation is not something a lab claims for itself. It requires rigorous assessment and periodic re-assessment by the accrediting body, including review of quality systems, method validation records, proficiency testing, and on-site audits.
Recognised accreditation bodies
Our testing partners operate under bodies such as A2LA (American Association for Laboratory Accreditation) in the United States, UKAS (United Kingdom Accreditation Service) for EU/UK partners, and other bodies recognised under the ILAC mutual recognition arrangement.
No conflict of interest
Because the lab is independent of Chemyo, it has nothing to gain from a favourable result. That is what separates an objective measurement from a vendor’s assurance. We are a US-based supplier of research-grade compounds, supplied for research use only.
How each batch is verified
Each batch undergoes a minimum of three forms of analytical verification — identity, purity, and concentration. Identity is typically confirmed using High-Performance Liquid Chromatography (HPLC) coupled with mass spectrometry (LC-MS) or nuclear magnetic resonance (NMR) spectroscopy, techniques that generate compound-specific fingerprints. Purity is reported against our standard of greater than 99% for all compounds, and for solution products the concentration is checked against the stated value. The methods drawn on across these checks include:
- HPLC-UV / HPLC-DAD — High-Performance Liquid Chromatography with UV or diode-array detection, used for purity and concentration quantification of small organic molecules.
- LC-MS / LC-MS/MS — Liquid chromatography coupled with mass spectrometry, for definitive identity confirmation using molecular weight and fragmentation-pattern matching.
- NMR spectroscopy — Nuclear magnetic resonance for structural confirmation, particularly for novel or complex compounds where mass spectrometry alone may be insufficient.
- Residual solvent analysis — Gas chromatography (GC-HS) where applicable, to confirm that solvents left over from synthesis do not remain above acceptable limits.
Access the certificate for your batch
Every Chemyo product carries a unique batch code printed on its label. That code is the direct link between the material in your hand and its own Certificate of Analysis — never a generic or pooled certificate.
Find the batch code
Locate the batch code printed on your product label. Each 50 ml solution is induction-sealed and batch-coded so it traces back to a single documented test.
Email your request
Send the batch code to sales@chemyolabs.co with the product name, and your order number if you have it. We aim to respond to COA requests within one business day.
Read your COA
The certificate identifies the testing laboratory, the analytical methods used, the results obtained, and the date of testing — documentation specific to your exact material.
What accurate testing protects in your research
Compound purity and concentration accuracy are not quality-of-life concerns in research — they are fundamental to experimental validity. A compound at 90% purity instead of the stated 99%+ introduces a 10% impurity load that may carry its own biological activity. A solution at 8 mg/ml instead of 10 mg/ml makes every dose in a study 20% lower than intended. Either error can render results unreproducible and keep work from publication. Per-batch, third-party testing exists to remove those variables before a product ships.
You can read more about the wider process behind every order on our quality-control page and our about page, review the literature behind each compound in the research library, or browse the catalog by way of the shop and the solutions category. All Chemyo compounds are supplied strictly for laboratory and research use only.
