Wood, oenological tannins, Liquid Extract, Wine, Spirit and Water

LEC routinely analyzes a very wide range of relevant chemical compounds (tannins, lactones, etc.) in different matrices (wood, liquid extracts or oenological tannins).
-
No volatil compounds by HPLC.
-
Volatil compounds by GCMS.
-
Coumarins by HPLC-FLD

Analysis of aromatic compounds from oak wood

Particularly well suited for monitoring aging in contact with wood.

Determination of vanillin and syringalhyde at trace thresholds (µg/L)

Two complementary analysis methods for the main compounds of interest likely to migrate into wine.

Coumarines Aglycones Analysis : Scopolétine, 4 - Methylumbelliferone, Umbelliférone et Esculétine

Compounds naturally present in wood, they are known to be interesting markers of the aging of spirits in contact with oak wood.
The
HPLC-FLD analysis can be carried out alone or in addition to non-volatile compounds (identical extraction)
