Kjeldahl equipment is specialised apparatus used to determine the nitrogen content in organic compounds, which is vital for assessing protein levels in various samples. The Kjeldahl method involves digesting the sample with concentrated sulphuric acid, converting nitrogen into ammonium sulphate. This process requires precise heating and typically involves a digestor for efficient digestion. Following digestion, the ammonia is distilled and quantified through a titration method. Kjeldahl equipment usually comprises a digestion unit, a distillation unit, and a titrator, all designed for accuracy and safety in the laboratory. Widely used in agriculture, the food industry, and environmental analysis, this method is essential for ensuring quality control and compliance with nutritional standards.
