The Tartaric Acid Assay Kit - Specific for the assay of tartaric acid in white / red wines and fruit juices.

Liquid Ready Reagent; Includes Homogenous Assay for Red Wine.
The Tartaric Acid test kit is a rapid, simple, reliable and accurate method for the specific measurement and analysis of tartaric acid in wine, fruit juice and other materials. This kit includes a homogenous assay for red wine that is amenable to automation. Supplied as a “ready to use” liquid stable formulation that is suitable for manual, auto-analyser and microplate formats.

Note for Content: The number of manual tests per kit can be doubled if all volumes are halved.  This can be readily accommodated using the MegaQuantTM  Wave Spectrophotometer (D-MQWAVE).

Determination of the Complexing Capacity of Wine for Zn Using the Absence of Gradients and Nernstian Equilibrium Stripping Technique.

Chito, D., Galceran, J., Companys, E. & Puy, J. (2013). Journal of Agricultural and Food Chemistry, 61(5), 1051-1059.

The complexing capacity of synthetic (0.011 M tartrate in 13.5% ethanol) and real wine (Raimat Abadia) in titrations with added total Zn concentrations up to 0.03 M has been determined following the free Zn concentrations with AGNES (absence of gradients and Nernstian equilibrium stripping) technique. A correction to find the preconcentration factor or gain (Y1) really applied at each one of the ionic strengths reached due to Zn additions along the titration has been applied. The standard implementation of AGNES to real wine led to the observation of two anomalous behaviors: (a) an increasingly negative current in the deposition stage (labeled as “HER” effect) and (b) a minimum in the currents of the stripping stage plot (labeled as the “dip” effect). A practical strategy to apply AGNES avoiding the dip effect has been developed to quantify properly free Zn concentrations. The van den Berg–Ružic–Lee linearization method (assuming the existence of just 1:1 complexes) has been adapted to consider the dilution effect and the ionic strength changes. Aggregated stability constants and total ligand concentrations have been calculated from synthetic and wine titration data. The found complexing capacity in the studied wine (CT,L = 0.0179 ± 0.0007 M) indicates the contribution of ligands other than tartrate (which is confirmed to be the main one).
