Summary

Ammonia Nitrogen(NH3-N) is a crucial parameter in water quality management
and wastewater treatment, regularly measured in laboratories, wastewater
treatment plants, food and beverage manufacturing, and water treatment facilities.
This analysis is essential for complying with environmental regulations and
monitoring nitrogen concentration in process.
Traditional test methods based on standard procedures are complex, timeconsuming,
and highly dependent on the operator’s proficiency, leading to
potential variability in results. This application note introduces a simplified analysis
method using the QX Water Analysis Spectrophotometer and Hach Ammonia
Nitrogen Reagent set.
The QX spectrophotometer allows direct measurement without the need for
manual standard curve preparation, thanks to pre-set parameters. This not only
reduces analysis time but also enhances user convenience.
