LabTech PT3000 Automatic Purge and Trap System

The PT3000 Automatic Purge and Trap System is designed for the detection of volatile organic compounds (VOCs) in water and soil samples. It features advanced trapping and water removal capabilities, precise internal standard addition, and technologies that prevent contamination and residue. Additionally, it offers intelligent and convenient functions for preparing target compound calibration curves and sample dilution, making it particularly suitable for high-throughput testing needs of users. The instrument is stable, reliable, and durable, and is widely applied in environmental protection, food safety, agriculture, and related fields.

Key Features

  • Outstanding Quality: Over 50 years of technical experience forming a reputable brand.
  • Superior Trapping Technology: Trap directly heated by electrical resistance without any wrapping, offering precise temperature control and rapid ramping; cools from 250°C to 40°C in ≤40s.
  • Advanced Water Removal: Room-temperature spiral centrifugal water removal, highly efficient without loss, water removal rate ≥96%.
  • Enhanced Response: Addresses common user challenges, providing superior response for VVOCs.
  • Precise Internal Standard Addition: Electronically controlled pressure ensures accurate addition within 1 second; the added amount equals the used amount with no waste.
  • Intelligent and Convenient Operation: Automatic preparation of calibration curves for target and surrogate compounds, freeing the operator’s hands.
  • Prevention of Contamination and Residue: Independent preparation for water and soil samples, soil flow path anti-blocking design, and multiple protective measures prevent contamination and residue.
  • Special Sample Handling: Automatic physical defoaming prevents foam sample contamination; purge lines use radiant heating, suitable for detecting highly polar VOCs.
  • Integrated Software: Unified software for the main unit and autosampler, providing easy operation and a user-friendly interface.
