OAK WOOD ARÔMATIC COMPOUNDS

Volatil, non-volatil, coumanins, phenolic compounds

LEC offers different services for the analysis of a very wide range of relevant chemical compounds from oak wood. The technical team has developed different methods to offer services according to your needs, quality control, monitoring of aging in contact with wood, research and development for any type of solid or liquid matrix;
> Solid: wood for barrels or shavings, tannins...
> Liquid: spirits, wines, water, hydroalcoholic solutions, wood extract...

POSSIBLE TO BE INCLUDED IN PACKAGES

Coumarins Aglycones

Compounds naturally present in the wood, they are known to be interesting markers of the aging of spirits in contact with oak wood.

> Analysis by HPLC-HLD can be carried out alone or in addition to non-volatile compounds (identical extraction).

> *Scopoletin, 4 - Methylumbelliferone, Umbelliferone and Esculetin

COMPLETE PROFILE

Volatile and non-volatile compounds

Non-volatile compounds: Analysis by HPLC in all solid and liquid matrices. We also offer the analysis of the 2 compounds syringaldehyde/Vanillin at trace concentrations of the order of µg/L in spirits by LLDME-GCMS.

Volatile compounds: This analysis carried out in GCMS, at concentrations of the order of ppb (µg/L) makes it a more demanding analysis in terms of sensitivity.

Thanks to the R&D work carried out, we have validated the analysis for solid matrices from the same extraction carried out for non-volatile compounds, offering both a complete profile of the sample and allowing a more accessible price offer.

Possibility of grouping services in the form of packages

ADDITIONAL ANALYZES

Phenolic compounds

Many of these phenolic compounds are also known as smoky flavors generated by burning organic materials like wood or peat.

> Composés "tourbés" : matrice liquide ou solide, prestations notamment pour les spiritueux (whisky) et les grains (après extraction) réalisé en HPLC.

> Composés "fumés" dans le vin : méthode par SBSE-TD-GCMS.
