YSI THM 1000 Selective VOC Analyzer

Overview Specifications
Overview

Ensures Safe Drinking Water without Sample Prep or Off-Site Analysis

YSI’s new THM 1000 Analyzer is an easy to operate, integrated Purge & Trap Gas Chromatograph (GC) that measures the four critical trihalomethanes (THMs) at ppb levels in less than a half-hour, on-site, right at your own facility. This integrated system is a powerful new tool that can help operators optimize water treatment at the plant and evaluate water age in the distribution system for improved monitoring of the formation of THMs, an EPA-regulated disinfection by-product.

Product Features
  • 30-minute analysis
    • Eliminates expensive and time-consuming off-site analysis for process control
  • Integrated Purge & Trap
    • No sample preparation required
  • Rapid operator feedback
    • Allows for immediate process adjustment capability
  • Customized PC software
    • Minimal operator interaction required to collect THM data
  • Push-button simplicity
    • Fast and easy operation; all-in-one sample purging, component separation, and data analysis
  • Dedicated instrument
    • Helps ensure the safety of public drinking water

The YSI THM 1000 offers sample purging, VOC (Volatile Organic Compound) component separation, and data analysis with the push of a button. Say goodbye to off-site analysis with accurate results delivered in only 30 minutes. This includes the analyzer, gas connection kit, calibration kit, and THM standard.

This integrated system is a powerful new tool that can help operators optimize water treatment at the plant and evaluate water age in the distribution system for improved monitoring of the formation of THMs, an EPA-regulated disinfection by-product.

THM 1000 Selective VOC Analyzer Highlights:
