Save hours of searching for GC-based solutions with OI Analytical’s preconfigured systems for analysis of Volatile Organic Compounds (VOCs) in water, soil, and solids based on USEPA methods. Use our expertise to customize an instrument that will meet your laboratory needs.

  • Overview

    The System VOC is the complete GC package, incorporating our new 4760 Eclipse Purge-and-Trap Sample Concentrator, Low-Dead-Volume Injector, Agilent® Technologies 6890 GC, and your choice of our optional autosamplers. The System VOC is also configured with a tandem PID/ELCD for analyzing halogenated and aromatic species found in USEPA Methods 601/602 and 502.2  

    Principal applications for the System VOC include: USEPA Methods 502.2, 503.1, 601, 602, 8010, and 8021; ISO 15009 and 15680; standard methods 6200C; halocarbons; aromatics and olefins; solvents; and hazardous wastes.
