Witryna8 cze 2008 · In many cases it is impractical to identify and synthesise the impurity. It is then usual to estimate the amount of impurity by assuming it has the same response as the active. A highly concentrated sample (1) is injected where the main peak is overloaded in order to give a reasonable response from the impurity.
