Ensuring the purity of catalysts involves multiple steps, starting from the sourcing of high-grade raw materials. Analytical techniques such as inductively coupled plasma mass spectrometry (ICP-MS) and gas chromatography-mass spectrometry (GC-MS) are employed to detect trace impurities. Additionally, rigorous purification processes, including recrystallization and filtration, are utilized to eliminate contaminants. Regular quality checks are performed at various stages of catalyst preparation and storage.
