[labnetwork] Liquid nitrogen and argon shortage

[Tom Britton]

Hi Manish,

Critical Systems recently released a facility management software system the besides other things, records gas usage on a day by day basis so you can see if you are trending down and when you have a spike on usage. It could help you get your usage under control.

If you want to see Ngoc on it, let me know.

Hi Manish,

It may be more related to a transport issue as described in article linked below...

... we have certainly had our own issues with its delivery, a lack of drivers, and changes to how our supplier operates.

Best Regards,

Hi Manish,



Some months ago we introduced a Nitrogen Generator in our system. It didn’t replace our original LN2 tank, but complemented it. All the purge gas for pumps is now supplied by this generator. In case of some technical problem happens we still have the N2 from the LN2 tank as backup.

Hello everyone,



We just learned that there is a severe shortage of liquid nitrogen and argon in the US. Our entire lab will be impacted by this and we will need to evaluate consumption of these gases for different tools in our Nano fabrication center and make priority for tools usage based on that. Nitrogen is used as a purge gas for pumps and equipment and we will be looking into tools that consume significant amount of nitrogen and how to minimize their use or use them more efficiently.



If you have any thoughts or ideas that will help with this issue, please share them.



Thanks,

Manish
