Determination of Eight Nitrosamine Impurities
April 17, 2023
This application note demonstrates that the Agilent 6475 
triple quadrupole LC/MS system can confidently quantify 
nitrosamine impurities at the low concentration levels 
specified by regulatory requirements. This method can 
be used to quantify these impurities in different ARB drug 
products, with some changes in chromatographic conditions 
based on the elution pattern of the drug product.
