we're just in the discussion/decision for a new UPLC, so I'm looking for fast answers...
Does anybody already have some experience with the Aglient 1290?
Are there any pro/cons vs. the Waters Acquity (beside the higher pressure limit, higher flow rate possibility, higher sampling rate of the PDA)?
Are these features really needed in UPLC method develompent or are these more to impress the customers? E.g. how much of column performance do I trade of for the higher flow rate? Would it then not be possible to use a smaller column?
Are the particle going to be smaller than 1.7 µm in the near future?
What about the "adjustable" dwell volume of the 1290? The presentation says that this is for the compatibility of different systems. Is this really physically adjusted or is this just an inbuild calculative correction of the gradient table, which can also be done manually (if one knows the theory)?
Thank you for your opinions.
