This highly sensitive and accurate method helps in identifying and quantifying even minute levels of impurities within a sample.
Gas Chromatography (GC) is another potent analytical tool particularly suited for volatile impurities. Here, the substance of interest is vaporized and then run through a column with a carrier gas serving as the mobile phase. The components are resolved based on their interaction with the column material or stationary phase. This method is particularly useful in detecting residual solvents that may be present as impurities in the final product. GC can also be paired with a mass spectrometer (GC-MS) to enhance detection and provide structural information about the impurities.
Mass Spectrometry (MS) is invaluable in characterizing unknown impurities due to its ability to provide molecular weight and structural information. This method is often used in conjunction with HPLC or GC and can deliver unequivocal identification of an impurity by breaking it down into smaller ion fragments and analyzing those fragments for molecular structure details.
Furthermore, techniques like Nuclear Magnetic Resonance (NMR) spectroscopy can be employed, providing detailed structural data and confirmation of the identity of the impurities identified through earlier methods. Together, these analytical methods form a comprehensive suite of tools that ensure thorough identification and quantification of impurities within Ornipressin to support safety and regulatory compliance.
