TI  - Analysis of trifluoroacetic acid and other short-chain perfluorinated acids 
      (C2-C4) in precipitation by liquid chromatography-tandem mass spectrometry: 
      comparison to patterns of long-chain perfluorinated acids (C5-C18).

AB  - A method has been developed to measure 29 perfluorinated acids (PFAs) including 
      short-chain perfluorocarboxylates (PFCAs) such as trifluoroacetic acid (TFA; C2) 
      and long-chain PFCAs, perfluoroalkylsulfonates, fluorotelomer acids, and two 
      perfluorooctylsulfonamides in water matrices. The method involves solid phase 
      extraction (SPE) using a weak anion-exchange (WAX) cartridge, an ion-exchange 
      high-performance liquid chromatography (HPLC) column separation, and tandem mass 
      spectrometry (MS/MS) detection. To our knowledge, this is the first HPLC-MS/MS 
      method to determine TFA in water at sub-ng L(-1) concentrations. The method is 
      selective, simple, and robust, capable of measuring 29 PFAs in a single analysis, 
      with overall recoveries of the target analytes ranging from 75% to 132%. The 
      method was applied to the analysis of rainwater samples collected from two cities 
      in Japan. TFA and several short-chain PFAs were the major compounds found in 
      rainwater.
