| Abstract: | Quantitative method to determine trace additive triphenyl phosphate in hydraulic oil by liquid chromatography/mass spectrometry/mass spectrometry (LC/MS/MS) was studied. Use multiple reaction monitoring (MRM) technology to record chromatographic peak flowed from high performance liquid chromagraphy (HPLC) . When concentration range of triphenyl phosphate is in 1-7 mg/L, the chromatographic peak area and concentration are of good linear relation. Experiment conditions of the method were also discribed. |
