The WitrynaResults: Spiking experiments with individual and complex impurity mixtures show the method can distinguish among samples differing in impurity content by 0.2% wt. The method has been applied to monitor changes in impurity profile among different batches of the same oligonucleotide and changes in the same batch over time (stability analysis).

WitrynaAn impure substance is a combination or mixture of two or more different substances that are not chemically bonded together. Purity is how pure a substance is or the degree to which a substance is free from contamination. An impurity is a substance that is mixed with, and contaminates, a desired substance.
