We run a hot-wire CVD process. We flow both inert and hazardous gases to achieve this. From what we know about our process, we know that it is very very sensitive to gas purity, accurate metering of gas flows, and extremely intolerant of water / oxygen contamination. We could really use some expert analysis of our situation to 1) accurately assess our current gas purities at several points in the system 2) make recommendations on what process or analytical equipment we may want to purchase to help us stay on top of this situation in the future (avoid long lasting, hard to detect problems).
As such we are asking ourselves the following sort of questions.. are the gases we are purchasing…
1) really what their CoA’s promise they are?
2) Remaining pure while in our bulk storage containment, and immediately downstream of it (i.e do we have moisture or other contaminants in our bulk tanks)
3) Remaining pure at the point of use in the process?
4) In particular do any of our process gases somehow have moisture or oxygen contamination that they are bringing into the process?
5) Do we have any leaks in our system that are allowing atmospheric contamination into a process gas stream.
What we really need is someone to come here and answer these questions for us (or at least give us clear steps toward answering these questions), and depending on the findings recommend ways we can stay on top of the situation going forward (analytical equipment to buy, etc)
Can anyone offer any suggestions on where to look for this sort of service, or happen to know of any particular company that does this sort of thing. I know of a one or two, but since it is a significant expenditure would like to be able to 'shop around' a bit.
I imagine we will find a gas analyzer to be a useful tool to have, but would prefer to hire an expert if possible to make purchasing recommendations.
Thanks!
