摘要：

The separation and detection of various silicon-based compounds are reported. The components of the sample are separated by nonaqueous reversed-phase gradient liquid chromatography. The eluting silicon species are detected with a direct current plasma atomic emission spectrometer. Poly(dimethylsiloxane) oligomers and trimethysilyl derivatives of sodium silicate solutions are used to demonstrate the technique. A detection limit of 0. 25 ng of Si/s is observed with the 251. 6-nm emission line. Typical precision is in the 1-5% relative standard deviation range.
