Impurity detection
WitrynaThe detection of impurities is achieved by UV or mass spectrometry (MS). The impurity profile of relugolix and semaglutide impurities can be established using HPLC-UV or HPLC-MS methods. HPLC-UV is a rapid and cost-effective method that can provide information on the presence and quantity of impurities in relugolix. However, … Witryna6 gru 2024 · In this paper, an impurity-detection system, including a grain-sampling device and machine vision system, was developed. Sampling device structure and impurity extraction algorithm were studied to enhance the …
