<div>good morning. We've always used UHP product for anything
that touches the device surface (blow off guns, chamber venting,
process gas, etc.). Utility N2 is used primarily for secondary
purging, like pump purges.<br clear="all">

Would it be overkill or a good idea to supply high purity
nitrogen (instead of utility nitrogen) to the blow guns
