Here is a related question:
We are thinking about purchasing an Agilent 8900 as an UPLC-QQQ system for
trace level organometallic compounds and sulfur speciation. It would
replace our Agilent 7500cx. We want to maintain our current more routine
capabilities but we do not have the infrastructure to run both. Therefore
my question is:
How well does the 8900 perform as a "regular" single-Q ICP-MS and how hard
would it be to switch back and forth between that mode and hyphenated
"If I have seen further, it is by standing on the shoulders of Giants"
"Somewhere I think I have read an alternative quotation "I have stood on
the shoulders of pygmies". It is a clever remark [...] There is, however
the sobering thought that in a land of giants and pygmies there is no
point in standing on the shoulders of a pygmy if one is a pygmy oneself"
"If I have seen further, it is because I was looking in the right direction"
