Recently I have become aware that nickel, according to the
"Metals Handbook" the standard work on this, resists attack from
hydrofluoric acid. It would therefore seem ideal for cleaning ICPMS
cones, or at least those that are entirely made from nickel.
Please don't tell me how nasty HF is - I've taken part in
previous and recent threads about this and although I'm in favour of
accentuating how dangerous it is I don't want to incur Mike
Cheatham's wrath by starting a new one.............
So, shouldn't HF be suitable for cone cleaning,
particularly if silicate samples are being analysed?
