title: [Determination of trimethyltin chloride in urine by headspace-gas chromatography].
abstract: OBJECTIVE
  To establish a detection method for trimethyltin chloride in urine by the Head space-GC.
  
  
  METHODS
  After derivatizing trimethyltin chloride, the urines was separated by the head space-gc, and then the trimethyltin chloride detected qualitatively and quantificationally.
  
  
  RESULTS
  In the concentration range of 0.02 ∼ 0.40 mg/L urinary trimethyltin chloride, showed a quadratic, r = 0.9992, detection limit was 0.005 mg/L, the relative standard deviation was 1.9% ∼ 2.5%, recovery was 92.0% to 100%, the urine samples can be saved at least 90 days in -18°C refrigerator.
  
  
  CONCLUSIONS
  The instrument, reagents involved in the detection require low, the operations to processing samples are simple, high sensitivity, less interference, good reproducibility, and suitable for quantitative and qualitative analysis, convenient to promotion.
