VOC detector

VOC detector is a portable or fixed electronic device used for real-time detection and measurement of volatile organic compound concentration in the air. It uses its precise "sense of smell" to transform intangible VOC pollution into clear and visible data, providing us with scientific basis for assessing environmental risks, ensuring personnel health, and preventing production accidents.

VOC detector is a precision instrument used for real-time detection and measurement of volatile organic compound concentration in the air. VOCs refer to organic chemicals that are easily volatile at room temperature, commonly found in coatings, adhesives, cleaning agents, decoration materials, and industrial production processes. Some of these substances pose a huge threat to human health, and even have a carcinogenic risk. Therefore, VOC detectors play an important role in environmental protection, industrial safety, and indoor air quality monitoring.

　　VOC detectorPerformance Characteristics

1. The innovative "dual column separation+central cutting+single FID" design achieves full coverage separation and analysis of PAMS substances, while also reporting NMHC/TVOC concentrations. One instrument can meet the monitoring needs of high and low hydrocarbons, significantly reducing customer usage costs compared to the "high carbon analyzer+low-carbon analyzer" solution.

2. Low temperature (-30 ℃) pre concentration technology effectively enriches and concentrates the target compounds to be tested, and rapidly performs thermal analysis, greatly improving the detection limit and meeting the detection needs of low or ultra-low concentration air VOC components.

3. Deep cold low-temperature water treatment technology efficiently removes interference such as water and CO2 in the sample air, greatly improves peak shape, prolongs chromatographic column life, and retains all components VOC (NMHC).

4. Using FID (hydrogen flame ionization) detector, the response is good, stable, and the linear range is wide, which meets the requirements of GB/T30431 and GB/T33864.

5. The detector has real-time self checking function, can judge the working status, and can automatically turn off the engine and ignite.

6. By using high-precision MFC to control the sample gas and EPC to control the nitrogen hydrogen air working gas, the flow rate is accurately controlled, effectively ensuring the accuracy of the test results.

7. It has a reference analysis method (editable) and supports two quality control modes: online dynamic dilution standard gas quality control and sampling tank standard gas quality control.

8. PC control, real-time data collection and transmission, automatic recording and storage of process data (flow rate, temperature, pressure, etc.), and support the output of chromatograms and measured concentrations in the form of reports or reports. It has the functions of historical data (including spectra) query and power-off memory.
