AN73455: Determination of Nitrite Impurity in Dalteparin Sodium using Ion Chromatography Be the first to rate this application


In this application note, the nitrite determination described in the USP monograph was evaluated with a Thermo Scientific Dionex IonPac AS15 column using an IC system. The method and conditions were exactly as described in the USP Dalteparin Sodium monograph. Key performance parameters were evaluated including the system suitability separation, linearity, limits of detection, accuracy, and robustness. One Dalteparin Sodium sample was analyzed. The percentage of nitrite result was compared with the USP acceptance criterium.
