KAIN is taking over the on-line VOC patent of TNO Kwaliteit van Leven, previously developed by the founder of KAIN in salaried employment. This patented invention can be used to purify dirty and high molecular samples on-line using GPC for example, prior to a quantitative GC/LC analysis. The intention is to develop the technique further and eventually to market it in cooperation with an instrument firm. The technique is described in detail in the enclosed article.
