Lipids from 200 nL of breast milk sample with M3/IQX. Total 942 hits after removal of generic crap.
Not bad, but the problem is narrow inlet of IQX. Badly want to acquire the same thing on Ascend with HCCT.

Our microflow-mnESI lipidomics article is finally out in Analytical Chemistry. For all those who wants better coverage, sensitivity or works with limited sample amounts.
Next chapter coming soon, stay tuned!

A nice new toy in the lab! Can centrifuge thick-walled LCMS glass vials (available from vendor, also with surface treatment).
But Waters TrueView also work pretty well ;)
Time to play with interesting low-volume sample preps!

Snapshots from the lab. Xmas-2024 "just for fun" experiments end up in some very useful solutions. Contents of the shiny metal box to be revealed somewhen during the spring -)
