Pulsed flame photometric detection (PFPD) for gas chromatography was applied to organotin compounds as standards and in environmental samples. Ethylated organotin species (n‐propyl‐, n‐butyl‐ and phenyl‐) were extracted from spiked artificial seawater and from an environmental sample. Selectivity towards tin is shown in the analysis of highly polluted seawater samples from a commercial port where no significant interferences are found. The self‐cleaning capability and long‐term stability of PFPD is shown in this work during 140 days of continuous operation. The absolute limit of detection for this capillary GC–PFPD technique ranged from 0.2 to 0.4 pg (Sn) for tetraethyl‐ to tetraphenyl‐tin, allowing determination of sub‐nanogram/litre concentrations of organotin compounds. © 1997 John Wiley & Sons, Ltd.
