Overview
The Automatic Purge and Trap Device is a fully automated analytical instrument designed for volatile organic compound (VOC) analysis in water, soil, and food samples. This system meets multiple regulatory standards including HJ639-2012, HJ686-2014, and HJ605-2011 for VOC determination using purge and trap/gas chromatography-mass spectrometry methods. The device features precise temperature control across multiple zones and automated sample handling capabilities for high-throughput analysis.
Key Features
The system incorporates multiple temperature-controlled zones with ±0.1°C accuracy, including a desorption temperature range up to 400°C with rapid heating rates exceeding 2000°C/min. The electronic refrigeration system achieves cold trap temperatures as low as -30°C. With 72 sample positions accommodating 40ml bottles, the device enables unattended operation for large sample batches. Continuously adjustable purging flow (0-500ml/min) and back blowing flow (0-200ml/min) provide optimal extraction conditions for various sample types.
Applications
This instrument is essential for environmental laboratories conducting water quality monitoring, soil contamination assessment, and food safety testing. It supports regulatory compliance testing for drinking water, groundwater, surface water, soil, sediment, and food matrices. The automated operation makes it ideal for routine analysis in commercial laboratories, environmental consulting firms, and regulatory agencies requiring reliable VOC quantification with minimal operator intervention.
