AB  - In this study a sensitive analytical method based on liquid 
      chromatography-electrospray tandem mass spectrometry (LC-MS/MS) was developed for 
      the simultaneous analysis of bisphenol A (BPA), bisphenol AF (BPAF), bisphenol B 
      (BPB), bisphenol E (BPE), bisphenol F (BPF) and bisphenol S in different paper 
      and board products, including virgin fibre samples and recycled samples. Analytes 
      were extracted from the paper matrix using a simple solvent extraction and 
      chromatographic separation was performed on a C18 core-shell (100 mm x 2.1 mm 
      i.d.; 1.7 microm particle size) column. The developed method showed good linearity 
      (R(2) > 0.9921) for all analytes. Absolute recoveries ranged from 71 to 115% and 
      precision in terms of reproducibility and repeatability (intra- and inter-day) 
      yielded in relative standard deviations (RSDs) of less than 15.0% and 17.4%, 
      respectively. The limit of detection (LOD) and limit of quantification (LOQ) for 
      the different analytes ranged from 0.29 to 0.40 microg kg(-1) paper and from 1.09 to 
      1.32 microg kg(-1) paper, being in the same range for all analytes. Quantitation of 
      the analytes was performed using the internal standard procedure, with 
      concentrations of < LOQ to 9599 microg kg(-1) for the different analytes. 
      Furthermore, a calculation of the maximum migration, assuming the 'worst case' 
      scenario of 100% migration was performed.
