Gas fittings: Chromatograph and Sputtering

AI Thread Summary
The discussion revolves around restoring a Plasma Sciences CrC-150 Sputtering system, specifically focusing on the source gas fittings. The user, Mike, is seeking assistance in identifying the correct components for the system, which includes brass compression fittings with a 1/4" mean thread diameter. He recalls that a chemist previously helped him assemble a stainless steel tube with stainless steel nuts and graphite ferrules, typically used in gas chromatography. Mike expresses a need for help in sourcing these parts, as well as finding a reasonably priced gas dryer/purifier and necessary adapters. The thread concludes with Mike confirming that the fitting he needed was a 1/8" Swagelok tube fitting, thanks to assistance from a representative at Torr.

Hello,

I'm attempting to restore my Plasma Sciences CrC-150 Sputtering system, and I'm having a terrible time working out the source gas fittings.
Each is a brass compression fitting with a roughly 1/4" mean thread diameter.

The last time I used this machine, a chemist helped me by assembling a 1/16" or 1/8" stainless steel tube with stainless steel nuts and graphite ferrules. At the time he said the components were normally used for his gas chromatograph.

I'd greatly appreciate help identifying these parts as well as finding a reasonably priced gas dryer/purifier and associated adapters.

Thanks in advance,

Mike

Hah! It was a 1/8" swagelok tube fitting.
Many thanks to a young man at Torr for getting me the answer.

Stay Warm My Friends,

Thread 'Solubility of MgSO47H2O in water'

It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...

Thread 'Why does having 8 valence electrons make an element inert?'

I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
