Diphenylamine Detection in Drinking Water

Author:JIANGXI AIYI HI-TECH CO., LTD. Click: Time:2026-09-22 15:50:51

Overview

Safe drinking water is fundamental to public health. According to global water quality frameworks—such as US EPA Method 525.2 and EU Directive 2020/2184—monitoring trace organic contaminants like Diphenylamine (C12H11N) is critical due to potential long-term health risks, including carcinogenicity and reproductive effects.

Even at extremely low concentrations, these contaminants can accumulate over time, making reliable, high-sensitivity detection an essential capability for environmental monitoring agencies, water utilities, and third-party testing laboratories.

Our Complete Analytical Solution

We offer a fully integrated solution for the high-sensitivity detection of Diphenylamine and similar trace organic contaminants in drinking water:

1. UHPLC System — Precision You Can Trust

The UHPLC System delivers:

  • Stable column temperature control, ensuring reproducible chromatographic conditions run after run
  • Ultra-low gradient delay volume, enabling precise retention times and sharp, well-resolved peaks

These performance advantages are essential for accurately quantifying trace-level contaminants in complex water matrices.

2. ODS-AQ C18 Column — Optimized Selectivity

The ODS-AQ C18 Column provides:

  • Superior selectivity and peak symmetry for both polar and hydrophobic organic compounds
  • Reliable performance under standard reverse-phase conditions, making it ideal for Diphenylamine and a wide range of semi-volatile organic contaminants

3. Method Adaptability — Regulatory Compliance Built In

Our solution is fully compatible with international regulatory testing workflows, including US EPA Method 525.2 and EU Directive 2020/2184, ensuring that your laboratory remains compliant with local environmental and health authority requirements.

Why Choose Our Solution?

Whether you are updating laboratory capabilities or expanding your testing scope, our chromatography instruments and consumables deliver:

  • High sensitivity for trace-level contaminant detection
  • Repeatability for consistent, defensible results
  • Reliable throughput for routine, high-volume water quality monitoring

Applications

  • Drinking water quality monitoring (municipal and utility laboratories)
  • Environmental monitoring and regulatory compliance testing
  • Third-party contract laboratories
  • Research on trace organic contaminants in water systems
