Why this conversion matters in chemistry
Targeted-proteomics serial dilutions is a place this matters. A 1 pmol/µL stock diluted 100-fold gives 10 fmol/µL — the working concentration for an LC-MS/MS sensitivity check or for spiking an isotope-labeled internal standard into a limited-sample cohort. The same dilution pattern bridges new and outgoing internal-standard lots without re-anchoring the entire calibration curve. Carryover between calibration lots remains the main source of systematic bias in these bridging studies. That 1000 fmol per pmol is the pico and femto prefix step, no more.
Formula
Worked Examples
The conversion anchor — the pico to femto prefix step.
About a sub-picomole working amount on a sensitivity-check injection.
1 fmol — about a typical LC-MS/MS detection floor.
10 pmol — about a typical ELISA-assay reagent amount.
