Detection of trace trichlorosilane in silicon tetrachloride
Thread Content
Now, it is necessary to detect the trace amount of trichlorosilane in silicon tetrachloride; what is a good method for this? Which institution can conduct the testing?
What is the level considered as a trace amount? Generally, gas chromatography is used to detect the content of trichlorosilane in silicon tetrachloride； If it is at the ppb level, the contents of B and P in substances like trichlorosilane can be determined using ICP-MS
Silicon tetrachloride is too prone to hydrolysis; it can corrode equipment, and it is rather difficult to analyze
I also want to know which institution can detect trace impurities in trichlorosilane. It’s urgent; if anyone knows of such an institution, please let me know. Thank you!
For universities, generally gas chromatography can be used for this.
Tianjin Jinbeli Technology Co., Ltd. has developed a specialized silicon tetrachloride testing and analysis system that enables both online and offline testing, and can determine the content of trichlorosilane.
:L – this seems to be something that laboratories in ordinary polysilicon factories in China can handle, right? It’s a bit too simple
