Chlorinated paraffins (CPs) are complex mixtures of compounds and isomers.
CPs contain short-chain CPs (SCCPs) and medium-chain CPs (MCCPs).
SCCPs and MCCPs were analyzed using GC-NCI-qTOF-HRMS.
CPs were quantified, and their accurate masses and detection limits determined.
The developed method allows the analysis of samples from a range of matrices.
