EPA Method 3535 Instrumentation Guide

EPA Method 3535 describes the solid-phase extraction (SPE) technique used to isolate organic analytes from aqueous samples, including groundwater, wastewater, and industrial effluents. This method is widely employed for extracting pesticides, herbicides, semi-volatile organic compounds (SVOCs), and other contaminants before instrumental analysis. By utilizing SPE, laboratories can achieve highly efficient extraction while minimizing solvent use and sample preparation time, making it an environmentally friendly alternative to traditional liquid-liquid extraction (LLE).

Following the SPE process, extracted samples require precise analytical instrumentation for accurate identification and quantification. Gas Chromatography (GC) and Gas Chromatography-Mass Spectrometry (GC-MS) are the primary techniques used for analyzing the extracted compounds. These instruments provide high-resolution separations and reliable detection, ensuring compliance with environmental regulations. Below, we highlight advanced analytical systems designed to meet the performance standards of EPA Method 3535, offering laboratories the precision and efficiency needed for accurate environmental testing.
