Isolated aquatic humic and fulvic acids were analysed with on-line size exclusion chromatography/electrospray ionisation mass spectrometry (SEC/ESI-MS). An eluent composition which enabled electrospray ionisation was identified. The SEC separation improved interpretability of mass spectra and may open up new possibilities for molecular weight determination of humic substances. A linear dose-response relationship over a factor of 20 was obtained and the limit of detection was 50ng/uL for humic… CONTINUE READING
