Estimation of Elemental Composition of Additives in Polymers Using Quick-CI and MassWorksTM
GC-MS offers a wealth of fragmentation data and a thorough, highly useful mass spectral library, so it is used for identifying unknown compounds. To identify unknown compounds, searches using a mass spectral library are commonly used. However, considerable difficulties with compound identification can be encountered if a compound detected is not registered in the mass spectral library. The Mass WorksTM software from cerno BIOSCIENCE mathematically calculates the accurate mass from the quadrupole MS mass profile. It then outputs candidate composition formulas using the accurate mass and isotopic ratios.This application sheet introduces the results of composition estimation using MassWorks for data acquired by means of the EI and CI methods with Quick-CI when analyzing additives in polymers.* MassWorksTM is a trademark of cerno BIOSCIENCE.
