3 Method summary
Electrical and electronic products or materials used in the analysis sample obtained GB/Z20288, crushed by liquid nitrogen, methanol ultrasonic extraction
take. In the right acidity to tetraethyl borohydride derivatization. Equipped with a flame photometric detector gas chromatograph (GC-
FPD) determination, external standard.
4 Reagents and materials
Unless otherwise indicated in the analysis using only recognized as analytical grade reagents and distilled or deionized water or equivalent purity.
