Micro-Kjeldahl Digestion and Distillation System

微量凯氏消解与蒸馏系统

When only 10–100 mg of sample is available, or acid waste must be minimised, the micro-Kjeldahl route makes sense. This system uses 50–100 mL tubes with 1–5 mL acid, digests at up to 400 °C in 20–60 min and distils each sample in 2–4 min. Titrate with a micro-burette or potentiometrically over 0.05–20 mg N.

Highlights

  • Works with 10–100 mg samples
  • Only 1–5 mL acid per digestion
  • Distillation in 2–4 min per sample
  • Micro-burette or potentiometric titration

Applications

  • Protein testing when sample material is limited
  • Costly or hazardous matrices such as toxins and drugs
  • Low-waste laboratories with acid disposal constraints
  • Research and teaching with small sample sets
