Analysis of Organic Fertilizers for Nutrients with AAnalyst 800 Atomic Absorption Spectrophotometer

This application note demonstrates the ability of the PerkinElmer® AAnalyst™ 800 atomic absorption spectrophotometer to analyze the micronutrients in several organic fertilizers. The results obtained from using the conventional AOAC Method 965.09 using dry ashing with a muffle furnace and EPA Method 3052, the official EPA method for the microwave digestion of siliceous and organic based samples, are compared.
