EFD-Q200Online Air Quality Analyzer (VOC Mass Spectrometry Detection)Selection of Environmental VOC Testing

The precise detection of volatile organic compounds (VOCs) plays a crucial role in maintaining the ecological environment and public health in the field of air monitoring in environmental medicine. EFD-Q200Online Air Quality Analyzer (VOC Mass Spectrometry Detection)With its advanced technology andtallPerformance has become an important means of detecting VOCs in the environment.

1、 Working principle

EFD-Q200 adopts a highly integrated modular design. Its core is based on mass spectrometry analysis technology. In a high vacuum environment, the ambient gas sample enters the ion source through a specially designed injection system. The ion source utilizes 70eV electrons (such as electron bombardment of the ion source EI) to convert neutral VOC molecules in the sample into ions. These ions then enter a mass analyzer, such as a four stage rod mass analyzer, to screen for ions of specific mass based on the mass to charge ratio, allowing them to enter the detector. The detector can choose a Faraday cup to directly record the size of the ion current, or use a secondary electron multiplier to significantly improve the detection sensitivity through multiple multiplications. Finally, the detector collects and amplifies the ion signal, which is processed by a computer to create a mass spectrum for qualitative and quantitative analysis of VOCs in the environment.

2、 Advantages and highlights

Real time and precise monitoringCapable of conducting 24-hour real-time online qualitative and quantitative analysis of VOCs in the environment, quickly and accurately determining the composition and content of various VOCs. Whether it is air quality monitoring in bustling cities or environmental detection around industrial parks, the changes in VOCs can be captured in a timely manner, providing first-hand data for environmental supervision.

Ultra high detection sensitivityWith extremely low detection limits, trace amounts of VOCs can be detected, and even extremely small amounts of harmful volatile organic compounds can be accurately identified, effectively assisting environmental law enforcement agencies in discovering potential environmental pollution hazards in a timely manner.
Flexible customization and adaptationFully considering the needs of different environmental monitoring scenarios, we support customizing different injection port forms to adapt to various complex sampling environments, whether it is high-altitude sampling, sewage sampling, or soil gas sampling, all of which can be adapted. Meanwhile, the communication format can also be customized according to user needs to ensure the stability and security of data transmission.
Temperature controlled injection guaranteeEquipped with a temperature controlled injection tube, the injection temperature can be flexibly set according to different boiling points of VOC gases. This can not only effectively promote molecular ionization and improve detection sensitivity, but also prevent sample residue and water condensation phenomena, ensuring the accuracy of detection results and stable operation of equipment, even under harsh environmental conditions, which can work reliably.
