<p class="MsoPlainText">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. <o:p></o:p></p>

Subject: [labnetwork] Liquid nitrogen and argon shortage</p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">Hello everyone,<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">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.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">If you have any thoughts or ideas that will help with this issue, please share them.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
