[labnetwork] Deuterated Silane detection

[Owain Clark]

Dear all, our researchers wish to add a SiD4 (Deuterated silane) line to the facility. Looking at the gas properties it is unsurprisingly incredibly similar to SiH4 as one might expect. And therefore one might also suspect that a SiH4 gas detection head would have near 100% cross sensitivity to it. However our gas detection system provider (Drager, polytron heads) cannot confirm this and has no data on the subject. Our safety staff are unsurprisingly not keen to proceed on the basis of "it should work".

Does anyone run this gas in their facility and if so would you mind sharing information on your detection system for it? Or if anyone knows of a company that can fabricate a 4-20mA capable gas detection head pre-calibrated for it? Or as a 3rd line of inquiry if anyone knows of a service whereby one of our SiH4 standard polytron heads could be cross-calibrated against SiD4 empirically that would also be of interest.

BR, Owain
