Analysis of Saxitoxin from Urine Using Dynamic FAB/MS
Abstract
Analytical procedures for the analysis of saxitoxin (STX) have been investigated using Continuous Flow Fast Atom Bombardment (CFFAB). Items investigated included derivative formation of STX resolution by micro capillary open tube columns (25 to 100 microns i.d.), CFFAB matrices, solvent flow rates, probe tip design and selection of fragment ions for analysis by Selected Ion Recording. Five-hundred picograms of STX can be reproducibly detected by SIR using a matrix made up of 5% thioglycerol, 1% acetic acid and 0.05% sodium dodecyl sulfate. Keywords: RA 1, BD, Lab animals, Guinea pigs, Rats, Saxitoxin, Dynamic FAB, Analysis, Mass spectrometer.
