VOC Sample Preparation with Built-in 100-Position Autosampler
Designed for seamless hyphenation with any brand of Gas Chromatography (GC) or Gas Chromatography-Mass Spectrometry (GC-MS) systems, the PTC-V delivers unparalleled analytical efficiency. Thanks to its patented moisture removal technology, precise Electronic Flow Control (EFC/AFC), and superior trap desorption rates, it minimizes water interference and ensures highly reproducible, stable, and accurate VOC analysis.

Applications & Compliance
Ideal for high-throughput laboratories, the PTC-V is widely used in:
- Environmental Analysis: Drinking water, wastewater, and soil organic pollutant testing.
- Food & Beverage: Analysis of volatile flavor compounds and odor components.
The system fully complies with stringent environmental analytical standards, including:
- HJ639-2012 (Water Quality – Determination of VOCs by P&T/GC-MS)
- HJ686-2014 (Water Quality – Determination of VOCs by P&T/GC)
- HJ605-2011 (Soil and Sediment – Determination of VOCs by P&T/GC-MS)
Key Features
Universal & Fully Automated
Universal Compatibility: Plug-and-play integration with any GC or GC-MS brand on the market.
Unattended Operation: Simply load vials into the 100-position tray; the comprehensive software handles all operations automatically, ensuring exceptional sample reproducibility.
Automated Internal Standards: Automatically adds internal standards to simplify workflows.
Intuitive Touchscreen: A large, built-in LCD touchscreen allows for real-time monitoring of temperatures and operational commands.
Smart Synchronization: Provides a synchronous interface to simultaneously start the GC and workstation upon injection.
Superior Thermal & Cooling Technology
- Advanced Peltier Cooling: The analytical trap utilizes thermoelectric (Peltier) cooling combined with air cooling, achieving temperatures as low as -30°C (at 20°C ambient) to satisfy highly demanding low-temperature enrichment requirements.
- Ultra-Fast Desorption: Direct resistance heating of the trap ensures a blistering heating rate of >3000°C/min, maximizing peak sharpness and resolution.
Maximum Contamination & Moisture Control
- Patented Moisture Management: Significantly reduces the transfer of water vapor to the GC/GC-MS, protecting your analytical columns and detector.
- Smart Foam Sensor: Built-in sensor detects foaming inside the purge tube, instantly protecting the sample lines and the entire analytical system from contamination.
- Inert Sample Pathways: All sample lines are constructed from PEEK or silanized inert stainless steel to eliminate carryover and active sites.
- Zero Cold Spots: All transfer lines and the 6-port valve are temperature-controlled, eliminating cold spots and preventing sample loss.
- Isolated Backflush: Trap and purge tube backflush gas paths are separated. Desorbed compounds from the trap are physically prevented from flowing back into the purge tube, eliminating cross-contamination.
- Heated Water Rinse: Supports hot distilled water rinsing of lines and the purge tube, alongside customizable cleaning cycles for both the sampling needle and purge tube.
- Direct Solid Sample Processing: Solid sample vials can be heated and injected with distilled water directly for in-vial magnetic stirring and purging.
Operating Conditions
- Power Supply: 220VAC ±22VAC, 50Hz ±0.5Hz
- Backflush Carrier Gas Pressure: ≤ 0.4 MPa
