ANALYTICAL AND SENSORIAL SERVICES
The analysis of volatile organic compounds (VOCs) is of crucial importance in assessing the quality and toxicity of various solid, liquid or gaseous matrices, such as natural and synthetic raw materials, extracts, perfumes, materials, various waste products, etc.
These compounds can significantly influence the olfactory and gustatory properties of products, as well as restricting their use or release within regulatory limits.

ESSENTIAL OIL ANALYSIS
The analysis of essential oils (EO) is crucial across various sectors, including perfumery, cosmetics, aromatherapy, and healthcare. The quality of essential oils is fundamentally linked to the verification of their chromatographic conformity with established standards, such as AFNOR standards and applicable pharmacopoeias in different countries. A comprehensive analysis of essential oils and their contaminants is an integral part of the regulatory requirements necessary for IFRA certification and compliance with cosmetic regulations.
In the field of aromatherapy, verifying the chemotype of an essential oil is particularly important. The chemotype reflects the specific chemical composition of the oil, which directly influences its therapeutic efficacy. By identifying the correct chemotype, practitioners can ensure they are using oils that deliver the desired effects while minimizing the risks associated with improper use.
At ScentXpertiseS, we bring over 20 years of expertise in this domain, enabling us to perform high-level analyses that adhere to the best practices in the industry. Our proficiency in methods such as gas chromatography with flame ionization detection (GC/FID) and gas chromatography-mass spectrometry (GC/MS) allows us to provide comprehensive and reliable assessments of essential oils.
The accuracy of our analyses not only ensures compliance with industry standards, but also supports our clients in making informed decisions regarding the use of essential oils in their products. Whether for therapeutic applications in aromatherapy or for fragrance development in perfumery and cosmetics, we deliver the critical information required for essential oil evaluation.

ODOUR ANALYSIS
Odour analysis is a strategic tool in perfumery, flavours, cosmetics, food industry, and environmental management. At ScentXpertiseS, we distinguish between two complementary and essential approaches.
On the one hand, sensory evaluation allows for the assessment of the overall olfactory profile of a product through trained sensory panels and standardized methodologies. This approach combines continuous training in natural and synthetic odours with vocabulary standardization. Our experts are trained, among others, in the Field of Odours and the Language of Noses, to evaluate fragrance performance, diffusion, and longevity, but also to characterize olfactory and environmental pollution, identify imbalances, detect off-notes, and support reformulation strategies.
On the other hand, the analytical evaluation of odorous compounds using gas chromatography coupled with olfactometry (GC/O) offers a precise and targeted interpretation. This method separates volatile molecules and identifies those with olfactory impact, traces the source of unwanted odours, and supports complex formulation projects involving rare raw materials, unstable matrices, or regulatory and budgetary constraints.
With over 20 years of experience in GC/O, our founder has developed a revolutionary methodology for the interpretation of olfactometric data (aromagrams/olfactograms), known as the Bubble Method®. This innovative visual system translates olfactory profiles using a synesthetic link between odours, intensity, detection frequency, and qualitative perception — creating hybrid representations that enhance understanding and decision-making.
With ScentXpertiseS, you benefit from a unique combination of scientific rigour and olfactory sensitivity, helping you to master and enhance the scent profile of your products.

ANALYSE DES COV
The analysis of volatile organic compounds (VOCs), BTEX (benzene, toluene, ethylbenzene, xylenes), and residual solvents (RS) is crucial to ensure the quality, safety, and regulatory compliance of fragranced, aromatic, cosmetic, and industrial products. These compounds impact sensory perception, product stability, and regulatory adherence (REACH, IFRA, ISO 16000, pharmacopoeias, etc.).
At ScentXpertiseS, we master the most advanced analytical techniques: gas chromatography coupled with mass spectrometry (GC/MS), gas chromatography-olfactometry (GC/O), and sample preparation by headspace (HS)—including solid-phase microextraction (SPME).
Mastering the HS preparation step is essential to isolate relevant volatile fractions, optimize reproducibility, and preserve the integrity of volatile profiles, especially in complex matrices such as creams, natural extracts, perfumes, and technical raw materials.
Our approach enables us to:
Identify and quantify residual solvents originating from extraction or manufacturing processes,
Detect BTEX compounds,
Trace compounds responsible for undesirable odours (off-notes),
Establish interpretable and actionable volatile profiles for R&D, reformulation, or compliance.
With over 20 years of experience in chromatographic analysis applied to perfumed and aromatic materials, ScentXpertiseS delivers reliable, actionable, and expertly interpreted results, combining analytical science with olfactory expertise.
