    • LC/MS analysis. Putative ten-component mixture samples were analysed by capillary LC-MS using a 150 × 0.32mm capillary column containing hypersil ODS 5μm packing, operating at a flow rate of 3 μl/min. Separations were achieved using a water/acetonitrile/trifluoroacetic acid gradient, increasing from 25% to 50% acetonitrile over 30 min. The mobile phase contained 10% glycerol as a matrix for the Continuous Flow Liquid Secondary Ionisation Mass Spectrometry (CF-LSIMS) interface. All of the eluent was transferred directly to the CF-LSIMS interface on a Kratos Concept-1S mass spectrometer scanning from 725 to 150 amu in 3 seconds. Direct MS analysis of the mixtures without prior separation was achieved by chemical ionisation on a VG Trio-3 triple quadrupole instrument using ammonia as the reagent gas. Component structures were confirmed by daughter ion MS/MS using argon as the collision gas.
