Dear colleagues, does anyone know what kind of chromatography column and detector can be used to determine the individual contents of a mixture of **dichlorosilane and phenyltrichlorosilane (with dichlorosilane being the main component)? Boiling points: trichlorosilane – 201°C, dichlorosilane – 205°C. Urgent! Waiting online, thank you all

The heating is carried out using the DB-1701 30*0.25*0.25 program; the initial temperature is 150, the heating rate is 15, the final temperature is 250, the vaporization temperature is 280, the detector temperature is 300, and the split ratio is 100:1. It’s a TCD detector. For more details, contact me on QQ at 313171922

I hope to get your help. I can’t add you on QQ; my QQ number is 88625033. Also, why does using your method allow us to separate the two groups of substances at 4 degrees? What’s the logic behind this? Looking forward to clarification.
