Online VOC Detection System

The online VOC detection system draws gas through a sampling probe, which is then preprocessed before entering the detector. It uses photoionization or gas chromatography to analyze the concentration of volatile organic compounds, with data transmitted in real-time to the control center. It is used for monitoring exhaust emissions and process control in locations such as printing workshops and coating production lines.
Selection
When selecting, consider the types of substances to be detected and the measurement range to match process requirements. Pay attention to the corrosion resistance of the sampling probe and the adaptability of the pre-treatment device. The detector type is determined based on accuracy requirements, with PID suitable for broad-spectrum detection and GC-MS suitable for component analysis. The system must have data storage and communication functions and be adaptable to the on-site installation environment.
