Nitrogen and Protein in Milk and Milk Products using FP828

This document outlines the importance of accurate protein determination in milk products and explains how the LECO FP828 Nitrogen/Protein Determinator achieves fast, reliable analysis. Using an automated Dumas combustion process in a pure oxygen vertical furnace, the FP828 ensures complete combustion and effective moisture removal before nitrogen is measured with a thermal conductivity detector. The instrument supports Helium or Argon carrier gases and offers selectable 3 cm or 10 cm aliquot loops to optimize sensitivity, reagent life, and cost-per-analysis. Aligned with ISO 14891, the FP828 provides a safe, rapid alternative to traditional Kjeldahl methods for routine protein testing in dairy materials.
