Abstract
A method for quantification of the amount of meso-lactide in a composition containing at least one other lactide stereoisomer with respect to the total amount of lactide stereoisomers in the composition. The quantification is based on measurements performed on absorptions in the Infra-Red region of the electromagnetic spectrum. Small amounts of meso-lactide in a lactide composition could be measured online in an easy and reproducible manner. Preferably near-IR has been used in this quantification method. The method can be applied with great advance in a lactide production device.
