Know what you’re testing.
Research quality starts with knowing exactly what is in a sample. We provide access to independent analytical testing for research samples: objective laboratory data on identity, purity, quality and contamination, documented through laboratory reports and Certificates of Analysis where applicable.
Provided in partnership with Axiom Performance Labs.
Why Independent Testing.
Data from laboratories with no stake in the result.
Findings tied to a batch, recorded in a laboratory report or CoA.
Purity, identity and contamination are different measurements — we help identify the right combination.
HPLC/UHPLC Purity
Chromatography separates the components within a sample to assess its chromatographic purity. It can help identify: the relative purity of a sample; additional peaks consistent with impurities or degradation products; batch-to-batch differences; and whether further analytical investigation may be appropriate.
Purity alone does not establish identity or quantity. Where stronger confirmation is required, complementary methods may be recommended.
Identity (mass spectrometry/LC-MS)
A sample appearing highly pure is only part of the picture. Mass spectrometry examines the mass characteristics of the material to provide evidence about molecular identity. Used alongside chromatographic testing, it gives a much stronger analytical picture of a research sample.
Endotoxin
Endotoxins are components associated with certain bacteria and can remain present even when viable bacteria are no longer detected. Specialist endotoxin testing quantifies endotoxin levels within a sample and forms an important part of broader quality assessment where relevant.
Sterility & Microbiological
Where appropriate, testing may include: sterility testing; microbiological assessment; bioburden testing; endotoxin analysis; and environmental or contamination-related investigation. Sterility, purity and identity are different measurements. A full assessment may need more than one method.
Heavy Metals & Contaminants
Testing can investigate contaminants such as heavy metals using techniques including ICP-MS. Depending on requirements, a programme may incorporate:
identity • purity • potency/assay • endotoxin • sterility • microbiology • heavy metals • stability.
Stability & Batch Programmes
Testing isn’t necessarily a one-time process. We support structured batch testing and stability programmes — assessing consistency between batches and monitoring how research materials behave under defined storage conditions over time.
