      reversed-phase and normal-phase liquid chromatography-electrospray ionization 
      tandem mass spectrometry].

AB  - A method of reversed-phase (RP)/normal-phase (NP)-liquid 
      chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS/MS) 
      was developed for the determination of distearyl dimethyl ammonium chloride 
      (DSDMAC) in textiles. The DSDMAC in textile was extracted by ultrasound-assisted 
      extraction using methanol as extraction solvent under the conditions of 70 
      degrees C and 420 W within 30 min. The three quaternary ammonium compounds of 
      DSDMAC were detected by LC-MS/MS in the selective reaction monitoring (SRM) mode. 
      The limits of detection (LODs) (S/N = 3) of DSDMAC detected by RPLC-MS/MS and 
      NPLC-MS/MS based on an amino-column were 0.1 mg/kg and 0.01 mg/kg, respectively. 
      The recoveries of DSDMAC spiked in the eight different types of blank fabrics 
      ranged from 85.5% to 103% with the relative standard deviations (RSDs) of 4.18% - 
      12.8% (n = 5) by RPLC-MS/MS method. Five laboratories were invited to take part 
      in the validation of the method, and the RSDs of inter-lab were 7.3% - 9.4% on 
      two reference samples. The method is fast, accurate and reproducible, and can 
      meet the demands of the determination of DSDMAC in textiles.
