Nima,

Are you sure that the odor is caused by silane?  PEX pipe has odors from many different volatile organic chemicals that are either used to manufacture or result from heating/oxidation.  I am attaching an article for your review.

Dear Dr.Dietrich

Thanks for your useful article. whats your idea about the main source of ETBE in PEX-b?

Nima,

ETBE results as a by-product of PEX manufacturing.

Dear Prof.Dietrich

Do you know a simple technique other than SPME/GC-MS to trace ETBE in a PEX specimen?

Any idea how to reduce the amount of this by-product during the process?

Best Regards

Nima

Nima,

The very low concentration of ETBE in PEX will require a sensitive method like SPME/GC to measure.  I am not aware of methods to reduce ETBE formation.
