In our lab we would benefit more from automation of the solid phase extraction than anything else. I know Horizon is doing this with large disk extraction but not many are trying it with cartridge based extractions.
With the newer SPE methods we are moving away from using large solvent evaporators where we evaporated 300ml or more of solvent from liquid liquid extractions to needing to evaporate about 15-30ml of solvent. Easy to blow that down but have to watch it closely near the end to make sure it doesn't go below 0.7ml or we start losing analytes. After that bringing to volume of 1.0ml and adding internal standards (usually 10ul) is the last part of the prep.
Automated calibration curve prep is nice, but that only takes us a couple hours once a month to do, so not as much time savings for us there.
I have tons of ideas about how to do it, but no practical way to test any of them lol.
