PROBLEM TO BE SOLVED: To provide a PCB analysis method which enables the sensitive measurement of lower chlorinated PCBs (the mono- and di-chlorinated PCBs) and in close relation with the official method. SOLUTION: The PCB analysis method for analyzing PCBs in test samples, liquids containing PCBs, includes: a column chromatography treatment process for treating the test samples by two-layer column chromatography using a silica gel and florisil; a sulfuric acid treatment process for treating an eluent, which has been eluted by a column chromatography treatment, with sulfuric acid; a neutralization process for performing a neutralization treatment on the material treated with sulfuric acid; and a PCB concentration measuring process for measuring the concentration of PCBs in the neutralized material. The PCB analysis method uses speedy, simple, and inexpensive preliminary treatments and has high correlation with the official method. COPYRIGHT: (C)2007,JPO&INPIT
