Ndtech is an individualized quality control TCA analysis technology for natural cork stoppers that offers the world's first natural stopper with undetectable TCA performance*.
Developed and patented by Amorim, NDtech individually analyzes the presence of TCA in each stopper, using an extremely fast chromatography. This high-precision technology can detect any stopper with more than 0.5 nanograms of TCA per liter* (parts per trillion, the equivalent of a drop of water in 800 Olympic swimming pools), which will be immediately removed from the supply chain.
* Releaseable TCA content equal to or below the quantification limit of 0.5 ng/l; analysis performed in accordance with ISO 20752.
