QX Spectrophotometer for Ammonia Nitrogen (NH₃-N) Analysis: Accuracy and Linearity Evaluation



This technical note demonstrates the QX water analyzer's high accuracy and excellent linearity in measuring ammonia nitrogen (NH₃-N) using Hach reagents. Results showed a %Error of 1.00% for the 1.0 mg/L standard and R² = 0.9999 over the 0.02–2.50 mg/L range, validating its reliability for water quality monitoring.
