Notes | The caliper spectrum taken at the peak apex of pentachloroanisole is representative of the overwhelming acetaminophen peak, but TOF-MS allows spectral deconvolution to produce a sample spectrum that matches well with the reference spectrum. No dSPE was performed on this sample; see Applications Note GNAN1263 for complete sample fortification and extraction details. |
