Environmental Analysis Instruments: Guardians of Our Planet

In today's world, environmental protection is of paramount importance. To safeguard our air, water, soil, forests, and wetlands, a variety of analytical instruments and equipment are essential. Here are some key environmental analysis instruments and their applications:

Air Quality Monitoring System (AQMS)

The Air Quality Monitoring System (AQMS) is capable of simultaneously detecting the concentrations of dozens of pollutants in the air, including SO2, NO, NO2, NOx, O3, CO, and particulate matter (PM2.5, PM10). It is widely used in environmental monitoring stations, roadside micro - stations, and building ventilation systems. By continuously monitoring air quality, AQMS provides real - time data to assess air pollution levels and helps implement effective air quality management measures.

Online Heavy Metal Analyzer

Online heavy metal analyzers use spectral analysis to monitor heavy metal content in water, wastewater, soil, and air in real - time. They are available in three types: portable X - ray fluorescence (XRF), laboratory bench - top, and online - ready. XRF spectrometers are non - destructive elemental analysis devices that work by exciting sample atoms to emit characteristic X - rays, enabling rapid qualitative and quantitative multi - element detection. These analyzers are crucial for monitoring heavy metal pollution in various environmental media and ensuring compliance with environmental regulations.

Online Water Quality Analyzer

Online water quality analyzers automatically and continuously monitor key water quality parameters. They are widely used in environmental regulation, drinking water safety, and industrial production. Some of the critical parameters they monitor include:

Turbidity: Normal value ≤ 1 NTU
pH value: Range of 6.5 - 8.5
Residual chlorine: For discharged water, 0.3 - 4 mg/L to ensure sustained disinfection
Total dissolved solids (TDS): Chinese standard ≤ 1000 mg/L

By monitoring these parameters, online water quality analyzers help maintain water quality standards and protect water resources.

Organic Pollutant Detector

Organic pollutant detectors target toxic organic compounds such as polycyclic aromatic hydrocarbons and pesticide residues. They use gas chromatography - mass spectrometry (GC - MS) for analysis. In the chromatographic separation stage, the sample is vaporized and separated via a gas chromatography column. In the mass spectrometry detection stage, the separated components enter the mass spectrometer's ion source, where they are bombarded into charged ions. These ions are then filtered by a quadrupole mass analyzer based on their mass - to - charge ratio and converted into electrical signals by a detector. The data output involves interpreting mass spectra to determine compound structures and combining chromatographic retention times for accurate qualitative analysis. Ion intensity is used for quantitative analysis. Additionally, a new approach involves mounting analyzers on drones to inspect VOC emissions across entire industrial sites, with data transmitted via wireless networks.

In conclusion, we have a wide array of analytical methods and equipment to address air, soil, and water remediation. The key is to effectively utilize these devices to ensure they function as intended and contribute to environmental protection.
