Theses
A highly specific and sensitive LC-MS/MS analytical method was developed and validated using gradient reversed phase liquid chromatography-tandem mass spectrometry (LC- MS/MS), interfaced using turbo-assisted electrospray ionisation (ESI) in negative mode for the analysis of DSP (okadaic acid (OA), dinophysistoxins (DTXs) and pectenotoxins (PTXs)) toxins in a variety of samples. There were no matrix effects present, proved by the good reproducibility achieved and the linearity of the calibration curves (r" > 0.999) in spiked mussel samples and standards. A DSP toxin profile study was conducted with bulk phytoplankton and mussels samples from the west coast of Ireland. All the samples were …
