Accurate, Real-Time Detection of VOCs in Water

Many volatile organic compounds (VOCs) are not detected by traditional online non-purgeable organic carbon (NPOC) analyzers, leaving potential gaps in water quality monitoring. AROMA technology provides real-time, ultra-sensitive detection of speciated VOC analysis in the field, with typical detection limits in the ng/L range, ensuring a more complete assessment of water safety.

Designed for Potable Reuse Applications

  • Quantifies reverse osmosis (RO) rejection performance for target VOCs
  • Detects specific VOCs before and after treatment in RO and granular activated carbon (GAC) systems
  • Measures trace-level VOCs that traditional monitoring systems may miss
  • Designed for continuous operation in demanding environments
  • Can be used alongside online NPOC (TOC) analyzers
  • Provides near real-time analysis for rapid results compared to traditional offline monitoring

Advanced Water Sampling Technology

Entanglement Technologies has amended the Direct Sparge Interface (DSI) system for online water sampling, enabling:

✓ Real-Time VOC detection for immediate water quality insights

✓ Continuous, unattended operation for long-term monitoring

✓ Flexible deployment for lab, field, and online applications

✓ Rapid response to fluctuations in VOC concentrations

Comprehensive VOC Detection

AROMA detects a wide range of VOCs, including halogenated VOCs, oxygenated VOCs, aromatics, and other organic contaminants.

Proven Performance in Research & Industry

Entanglement Technologies has partnered with leading water research institutions and utilities to push the boundaries of VOC monitoring in water systems. As part of a Water Research Foundation (WRF) study, the AROMA analyzer is being deployed to detect targeted VOCs at ultra-low detection limits (ppb/ppt) before and after wastewater treatment. This cutting-edge approach helps utilities ensure water quality, optimize treatment processes, and stay ahead of emerging contaminants.
