<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt">Hi Everyone,</span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt"> </span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt">I received a question from another lab on campus here and I’m not sure of the correct advice, I was hoping to rely on this experienced community.</span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt"> </span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt">This lab in question is interested in using reactive metal materials (Ba, Sr, etc..) in one of their UHV deposition tools. Since these materials are reactive in air, they were shipped immersed
in an oil. They were asking me about the best way to clean off the oil prior to installing the material in their deposition system. I believe they have already tried IPA and were not too happy with its effectiveness. The vendor recommended “100% mineral
spirits”, but a quick google search indicates that this is a sort of vaguely defined solution of short chain hydrocarbons (alkanes?). I was wondering if anyone has experience they could share regarding this type of problem and how they cleaned their materials?</span></p>
