Extraction techniques
SPE : Solid Phase Extraction
Solid-Phase Extraction (SPE) is a sample preparation technique that allows extraction, purification and enrichment of analytes before quantification.
Solids/Liquids Extraction
Solid-liquid extraction allows the extraction of a substance from a solid into a liquid.
SBSE : Stir Bar Sorptive Extraction
Stir Bar Sorptive Extraction (SBSE) is a technique for extracting very small amounts of analytes from matrices without using solvents.
Liquid/Liquid Extraction
Liquid-liquid extraction is a sample preparation technique. This technique consists in a transfer of matter between two non-miscible liquid phases.
Examples of application areas
THE FOLLOWING LIST OF APPLICATION AREAS IS NOT EXHAUSTIVE
Agri-food
With 10 years of experience in the food industry, we have expertise in the analysis of bioactive compounds such as antioxidants, applicable to food raw materials as well as to finished products. For this purpose, we use extraction and chemical analysis methods specifically adapted to each type of food or beverage that have been developed in-house by our team.
We perform a broad spectrum screening by Liquid Chromatography-Mass Spectrometry (LC-MS) or a unique antioxidant activity detection system (LC-AOx) allowing the detection and semi-quantification of hundreds of phenolic or other compounds, as well as antioxidant compounds. Thanks to our database, our computer and statistical processing software, we can identify the markers of a product, the compounds of interest or even find the best manufacturing processes for a product.
We are also able to analyze, detect and identify saponins in alfalfa leaves thanks to the collaboration with the University of Applied Sciences Weihenstephan-Triesdorf which has resulted in several publications. The analysis of the alfalfa samples was performed by liquid chromatography coupled to high resolution mass spectrometry (UPLC-HRMS). This analysis allowed the detection and identification of a large number of compounds such as flavonoids, phytoestrogens and saponins. Saponins and other compounds were characterized using reference literature and the TWISTAROMA database.
Cosmetics
We perform a broad spectrum screening by liquid chromatography with a unique coupling of antioxidant activity detection (LC-AOx) to detect and semi-quantify phenolic and antioxidant compounds in all raw materials for cosmetic use.
We carry out the characterization of phenolic compounds, antioxidants and all molecules from plants on all types of matrices from various fields of application.
Extraction techniques
SPE : Solid Phase Extraction
Solid-Phase Extraction (SPE) is a sample preparation technique that allows extraction, purification and enrichment of analytes before quantification.
SPME : Solid Phase Micro-Extraction
Solid Phase Micro-Extraction (SPME) is used to extract chemicals from various types of matrices. SPME does not require solvents.
SBSE : Stir Bar Sorptive Extraction
Stir Bar Sorptive Extraction (SBSE) is a technique for extracting very small amounts of analytes from matrices without using solvents.
HSSE : HeadSpace Sorptive Extraction
HeadSpace Sorptive Extraction (HSSE) is a solid phase microextraction technique that identifies odorous compounds present in the air surrounding various matrices.
Extraction Solide/Liquide
Solid-liquid extraction allows the extraction of a substance from a solid into a liquid.
Extraction Liquide/Liquide
Liquid-liquid extraction is a sample preparation technique. This technique consists in a transfer of matter between two non-miscible liquid phases.

Agri-food
With 10 years of experience in the food industry, we have expertise in the analysis of aromatic compounds applicable to food raw materials as well as to finished products. For this purpose, we use extraction and chemical analysis methods specifically adapted to each type of food or beverage that have been developed in-house by our team.
For flavors, we perform a broad spectrum screening by Gas Chromatography-Mass Spectrometry (GC-MS) to identify and semi-quantify hundreds of volatile compounds. Thanks to our database, our computer and statistical processing software, we are able to identify the markers of a product, the aromatic defects (off-flavors) or to find the best manufacturing processes for a product.
In addition, we offer the quantification of targeted compounds according to our customers' requests. Some examples: determination of safrole in spices, determination of trimethylamine in fish powders, quantification of terpenes, esters and aromatic phenols in beer and wine, ....
We are also able to detect contaminants such as residual solvents, Polycyclic Aromatic Hydrocarbons (PAHs), or pollution coming from the migration of packaging materials or having been in contact with food.
Cosmetics
We propose a method to quantify allergens in cosmetic products (creams, oils, serums, shampoos, ...). The method allows the detection of allergens listed in the European regulation (list of 26 allergens, soon extended to 57 compounds)
We carry out the characterization of volatile compounds on all types of matrices from various fields of application.
