PristiQuant™
With over 40 tests,
we redefine industry standards
PristiQuant Essential Oil Testing
A Standard, Not a Slogan
Quality at Delune is measured, not claimed. PristiQuant™ is our proprietary testing protocol: a science-led, multi-checkpoint system that holds every essential oil to one exacting benchmark for purity and safety.
Precision in Every Drop
Each batch is evaluated from first impression to molecular fingerprint. Visual and olfactory assessment sits alongside advanced instrumentation, including Gas Chromatography–Mass Spectrometry (GC-MS), Fourier-Transform Infrared Spectroscopy (FTIR) and DNA authentication, to confirm that every oil is true to its botanical source.
40+ Analytical and Purity Tests
The PristiQuant™ Assurance Spectrum brings together more than 40 tests, from microbial screening and pesticide residue analysis to optical rotation and antioxidant content. The result is verified quality, safety and traceability for every oil. The full protocol is set out below.

| Chiral Analysis | Determine the chirality of certain components in the oils. | Chiral chromatography or other methods are used to analyze and quantify the different stereoisomers. |
| Ethical Sourcing Verification | Ensure the oils are sourced sustainably and ethically. | Verification is done through supply chain audits and documentation to confirm ethical practices. |
| Certificate of Analysis (CoA) | Provide transparent information on test results for each batch of oils. | Each batch of oils is tested, and a CoA is issued with detailed results, which can be accessed by customers. |

Excellence at Every Step
-
Safety, Without Compromise
Safety is non-negotiable. Every oil is screened for microbial contaminants, heavy metals and other potential hazards, and sourcing is held to the same standard, with care for the growers and environments we depend on.
-
Authenticity, Verified
Authenticity is established through analysis, not assumption. Each oil is checked against its botanical profile, so what is in the bottle is exactly what the label says.
-
Consistency, Bottle After Bottle
Nature varies from harvest to harvest. PristiQuant™ holds every oil to the same benchmark, so the quality you trust today is the quality you receive next time.
PristiQuant™-Certified Quality
Every Delune essential oil is held to the PristiQuant™ standard: more than 40 tests covering purity, safety and authenticity. For ethical sourcing at its most rigorous, our Field to Sealed™ promise follows our Organic Wellness Grade oils from the field where they are grown to the moment they are sealed.
What is PristiQuant™?
PristiQuant™ is Delune's own quality system: a suite of more than 40 tests applied to our essential oils. It checks what an oil is, what it should not contain and how it should look, smell and perform, so that every bottle is examined rather than assumed.
What does the PristiQuant™ Assurance Spectrum cover?
The Assurance Spectrum is the full range of checks behind each oil. It spans the senses (appearance, colour and aroma), identity (FTIR analysis and optical rotation), freshness (peroxide value) and safety (flash point, formaldehyde and contaminant screening). The complete list is set out in the table above.
How does PristiQuant™ support safety and authenticity?
Each oil is screened for microbial contaminants, heavy metals and other potential hazards, and its composition is analysed to confirm it is exactly what the label says. Authenticity and safety are verified, not taken on trust.
How is a PristiQuant™ oil different?
Essential oils vary with harvest, origin and handling. PristiQuant™ is how we keep that variation in check: every oil is measured against the same standard, so what reaches you is consistent from one bottle to the next.
How does PristiQuant™ relate to Field to Sealed™?
PristiQuant™ is the standard behind all Delune essential oils. Field to Sealed™ goes a step further for our Organic Wellness Grade oils, following each one from the field where it is grown to the moment it is sealed. Discover Field to Sealed.
Where does the name PristiQuant™ come from?
It joins two ideas: pristine, meaning pure and untouched, and quantified, meaning measured rather than assumed. Purity, for us, is something we test for, not simply a word on a label.
With over 40 meticulous tests, we redefine industry standards.
