AB  - A headspace solid-phase micro extraction (HS-SPME) and gas chromatography-tandem 
      mass spectrometric (GC-MS/MS) method is described to detect hydrazine after 
      derivatization with 1,1,1-trifluoro-2,4-pentanedione (1,1,1-TFPD) to 
      3-methyl-5-(trifluoromethyl) pyrazole in industrial waste water. The following 
      optimal HS-SPME conditions were used: 85 mum-carboxen-polydimethylsiloxane fibre, 
      100 mg L(-1) TFPD, saturated NaCl, an extraction/derivatization temperature of 
      80  degrees C, a heating time of 40 min, and a pH of 9.5. Under the established 
      conditions, the detection and quantification limits were 0.002 mug L(-1) and 
      0.007 mug L(-1) by using 5 mL of waste water and the intra- and inter-day relative 
      standard deviations were less than 10.2% at concentrations of 0.02 and 
      0.1 mug L(-1). The calibration curve showed good linearity, with r(2) = 0.998; the 
      accuracy was in the range of 98.0-103%; and the precision of the assay was less 
      than 10.2% in industrial waste water. Hydrazine was detected over a concentration 
      range of 0.011-0.074 mug L(-1) in 5 of 20 waste water samples.
