TraceSELECT™ Ultra and TraceSELECT

  • ultra-pure acids, bases, and salts for smelting and wet digestion in environmental, water, and food analysis
  • sample preparation for trace analysis requires reagents of the highest purity; our TraceSELECT Ultra products for ultra-trace analysis at ppb and even ppt levels are produced by sub-boiling distillation
  • the acids, bases, and salts in the TraceSELECT series have been developed for sample preparation and analysis in the ppb (μg/kg) trace range
  • packaged in high-quality containers appropriate for each product
  • the reagents are produced and bottled under clean-room conditions
