QUESTION:

We are experiencing chemical level changes in our gas delivery system bubbling process.  You have staff that consults on this?

 

ANSWER:

We do.  The bubbling process is critical, and it is important that the gas flow and liquid reagent temperature remain constant. In most systems, the chemical level changes in the bubbler over time, which enhances the cooling effect and reduces bubble path length. This changes the vapor pressure, reducing vapor concentration delivered to the deposition tube. It is very helpful to be able to observe the bubbler chemicals.
