AB  - Monolithic silica spin column extraction (MonoSpin-SPE) was developed as a 
      simple, sensitive, and eco-friendly pretreatment method which combined with 
      ultra-fast liquid chromatography-mass spectrometry (UFLC-MS) to determine the 
      levels of six phthalate esters, dimethyl-(DMP), diethyl-(DEP), dipropyl- [DPrP], 
      butyl-benzyl-(BBP), dicyclohexyl(DcHP), and di- n-octyl-(DOP) phthalate in 
      physiological saline samples. Under optimized experimental conditions, the method 
      was linear in the following ranges: 0.2- 50 mu/L for DMP, DEP, DPrP, DcHP and DOP; 
      5 - 100 mu/L for BBP. The correlation coefficients (R(2)) were in the range of O. 
      9951 - O. 9995 for all the analytes and the limits of detection (LODs) and limits 
      of quantification (LOQs) were in the ranges of 0.02 - 0.9 mu/L and 0.08 - 2.7 mu/L, 
      respectively. The pretreatment process showed good reproducibility with inter-day 
      and intra-day relative standard deviations (RSDs) below 8.5% and 11.2%, 
      respectively. This method was used to determine the levels of six phthalate 
      esters in physiological saline samples and the recoveries ranged from 71.2% to 
      107. 3%. DMP and DEP were found in actual physical saline samples (brand A and 
      brand B).
