Introduction 2-Nitrobiphenyl as a stationary phase for the separation of methylchlorosilane and silicon tetrachloride. It is less toxic than nitrobenzene and can completely separate the four components at a column temperature of 55 ° C. 2. Introduced a sample introducer for capillary crushing to prevent chlorosilane hydrolysis. 3. Describes a simple and robust structure, easy to manufacture metal tungsten filament thermal conductivity pool.
