     We recently came across a gas tank which is dated 1969 and is labeled

     Susan,
     
     I seem to recall that GM Qgas supplied for flow-cell detectors such as 
     those employed for radiochromatogram scanners testing tritiated 
     compounds....is likely to be helium with 2%[?] isobutane being the 
     organic quencher. Nuclear Chicago is long gone, but the product was 
     labeled for them by a specialty gas supplier anyhow, and perhaps one 
     that services UCSB would likely take that old bottle away for you.
     
     For what its worth...
