pmoll
pmol/L, or picomoles per liter, is a unit of molar concentration used to express the amount of a substance in a liter of solution. It represents a very small concentration: one picomole (10^-12 moles) of solute in one liter of solution. In practice, 1 pmol/L is equivalent to 1 pM (picomolar) when written in shorthand.
The unit is widely used in biochemistry, clinical chemistry, and environmental science to report low-abundance compounds
Converting pmol/L to mass concentration depends on the solute’s molar mass. If a substance has molar mass
Common measurement techniques include highly sensitive immunoassays (e.g., ELISA), liquid chromatography–tandem mass spectrometry (LC-MS/MS), and other
