<whitequark> _Sync_: lookin over some chemical suppliers
<whitequark> let's say HF for cleaning, how pure should it be? they offer what I think is the grade with <10^-5% of impurities
<whitequark> less than 2.7e-5% according to the datasheet
<whitequark> $40/5l

<whitequark> hm so that's <270ppb. commercial SEMI grade 2 is <10ppb
<whitequark> i'm gonna declare that "good enough"
<nmz787> "This ion mass spectrometer and the associated gas supply manifolds, dry boxes for element storage, control console, and laminar flow hoods at the targets (2) occupies a floor space about 20 ft by 35 ft. A list of components follows, with technical and philosophical discussion for some components."
<whitequark> their setup is massive
<nmz787> have you seen pics, or just going by that sentence? (I'm reading the word doc now, but on Linux so not sure if images got lost)
<whitequark> 300 A magnets
<whitequark> 400kV accelerating voltage
