EPA Method 506 Instrumentation Guide

EPA Method 506 is an approved U.S. Environmental Protection Agency protocol for determining phthalate esters in drinking water using gas chromatography with photoionization detection (GC-PID). It is designed to identify and quantify compounds such as DEHP, DBP, and DEP at low microgram-per-liter levels. For laboratories to achieve consistent and reproducible results, selecting a high-performance GC system with sensitive PID detection is essential. Proper instrumentation ensures method compliance, enhances data reliability, and supports regulatory drinking water monitoring programs.
