The present report demonstrates that thermospray liquid chromotography/mass spectrometry (LC/MS) calibration can be easily achieved by the observation of water cluster ions in filament‐on or discharge ionization modes. Cluster ions of sizes ranging from 1 to 44 water molecules are readily observed and thus are useful over the mass range from 17 to 792 Da.
