How much does the VOC online monitoring device cost

ZWIN-VOC Gas Chromatography VOC Online Monitoring Instrument

Product Overview

This product belongs to the quality monitoring instrument, which not only has the characteristics of high sensitivity and wide linear range, but also is relatively insensitive to changes in operating conditions and has good stability. It is particularly suitable for routine analysis of constants or trace amounts, as it has a fast response and can be used in conjunction with capillary analysis technology to achieve rapid analysis of trace amounts. It is a widely used gas chromatography instrument.

Product Principle

Gas chromatography analysis technology is a technique for separating and analyzing multi-component mixtures.Using gas as the mobile phase (carrier gas), when the sample is sent into the injector and vaporized, it is carried by the carrier gas into the packed column or capillary column. Due to the differences in boiling point, polarity, and adsorption coefficient of each component in the sample, each component is separated in the column. Then, the detector connected to the column detects each component in order based on its physical and chemical properties. The converted electrical signal is then sent to the chromatography workstation, where the gas chromatogram of each component is recorded and analyzed to obtain the analysis results of each component. The working principle diagram is shown in the following figure:

Product Features

⊙ The fully automatic online non methane total hydrocarbon analysis system has functions such as precise control, data acquisition, integration calculation, and data upload.

⊙ After an unexpected power outage and restoration of power supply, the microcomputer, instrument temperature control, instrument analysis, data upload, and other functions will fully start automatically.

⊙ It can automatically cut off hydrogen gas and sound an alarm after FID accidental fire extinguishing.

⊙ It can simultaneously analyze multiple gases such as total hydrocarbons, methane, and benzene derivatives.

⊙ Calibration, analysis, real-time display, maintenance and other functions of chromatographic components can be completed through a simple interface operation.

⊙ The software interface is simple and easy to use.
