Hi everybody,

I am a PhD student in Korea. I intend to analyze siloxane. Now I prepare the standard to set up the method but I have some troubles about linear siloxane.
Normally, they analyzed linear silioxanes (l4-L16) based son silicone oil Polydimethylsiloxane (PDMS; viscosity 5cSt).
Do you know how to determine the concentration and compostion of those linear in the PDMS mixture using GC/MS?

Thanks in advance.
