How to prepare HCl gas from HCl acid
How to prepare HCl gas from HCl acid
(OP)
Hi,
I heard that HCl gas could be effective for cleaning the quartz tube in the high temp. furnace. But, seems there is no commercially available HCl gas. So, we are planning to prepare HCl gas using HCl acid we have in our lab. Could you tell me how to prepare HCl gas using HCl acid? I'm not sure what solutions are required for preparing HCL gas exactly, the recipe, and the needed equipments.
Thank you.
