Technical Bulletin No. 0551: NCASI Procedures for the Preparation and Isomer Specific Analysis of Pulp and Paper Industry Samples for 2,3,7,8-TCDD and 2,3,7,8-TCDF
This technical bulletin describes the sample preparation and isomer specific analysis procedures NCASI has developed in support of the industry programs investigating the source and significance of 2,3,7,8-TCDD and 2,3,7,8-TCDF in pulp and paper industry matrices. Part I describes the sample preparation procedures which insure the stability and homogeneity of the samples. Part II describes the matrix-specific extraction, cleanup and isomer-specific GC/MS analysis procedures.
