Reducing processing time, Kjeldahl tablets and reagents are added to thoroughly digest samples. Having pre-weighed ingredients, the international standard additives successfully control testing conditions for reproducible results. After adding the catalysts and auxiliary reagents, samples will enter the dissolution and oxidation stages where component conversions occur. Used in routine element calculations within the food and environmental industries, the Kjeldahl tablets and reagents guarantee both organic and inorganic samples remain stable during tests.
