I don't follow. What's the gas? Anyhow, it seems your CCl_4 surface is 
sublimating, which might not be surprising.

I suspect this is just a language issue, but "expect" in English carries 
the implication that someone is obliged to make an answer. All of us 
here who might answer your email are volunteers. A paragraph like "I'll 
look forward to any answers. Thanks a lot!" will avoid annoying people :-)
