Application: Tri-o-tolyl phosphate may be used as an analytical reference standard for the determination of tri-o-tolyl phosphate in:
•Surface water and wastewater effluent samples by liquid chromatography coupled to tandem mass spectrometry equipped with electrospray ionization (LC-ESI-MS/MS) operating under the multiple reaction monitoring (MRM) mode of detection.
•Human hair and nails by liquid-liquid extraction (LLE) and gas chromatography-mass spectrometry (GC-MS).
•Indoor air, dust and window wipes by GC-MS/MS.
•Outdoor air samples by ultra-performance liquid chromatography coupled to triple quadrupole mass spectrometry (UPLC-QqQ-MS/MS) equipped with ESI source and MRM detection.
