โฆ Synopsis
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.

Of the several approaches used to interface liquid chromatography with mass spectrometry, the thermospray interface has evolved as the most popular and applicable for the analysis of polar and labile organic compounds. Since a separate ion source must be used for thermospray, separate tuning and cal
