Recently, Thermo Fisher Scientific announced the release of an application note describing its analysis of red wine using ultrafast chromatography. Red wine is a good source of antioxidants and is said to contain natural compounds that may be beneficial to human health.

The application note titled “Direct Analysis of Red Wine Using Ultra-Fast Chromatography” describes a method using Thermo's LTQ Orbitrap XL hybrid mass spectrometer combined with Accela U-HPLC to identify and quantify the antioxidant constituents in red wine. As red wine is a complex mixture this makes analysis of natural compounds difficult.

In this application note phenolic compounds in red wine that are considered to be most beneficial to health were identified and a variable difference across two harvest years was observed. Researchers also performed comparative analyses using the Thermo Scientific SIEVE 1.2 software defining significant change as a minimum of two-fold concentration difference between the two harvest years.

The overall results demonstrate that there is a significant difference in concentration levels for different compounds, especially the phenolic compound quercetin, over the two harvest years analysed.

More information about this application note and the products used within is available on the website www.thermo.com/redwine or alternatively you can e-mail [email protected] or phone +1 800 532 4752 to request a copy.
