Abstract:

Total response factor correction method and multiple linear regression method were adopted to quantify the sum of short chain chlorinated paraffins (SCCPs) in chlorinated paraffin mixtures. Both methods were based on electron capture negative ionization mass spectrometry. The results showed that high SCCPs quantitative accuracies were obtained by the two methods both with eliminating the potential interferences of mediumchain chlorinated paraffins. However, both two methods were slightly dependent on the ranges of calibration solutions. Dilution of the sample solution was necessary when performing these two methods. Besides, multiple linear regression method was suitable for more wide-quantitative-range of SCCPs than total response factor correction method.

Key words: multiple linear regression method, short chain chlorinated paraffins (SCCPs), total response factor correction method
