Volatile organic compound mass spectrometer

The volatile organic compound mass spectrometer has an alarm function for concentration exceeding the standard. Once the concentration exceeds the standard, the alarm light will sound and the interface will display an alarm. Both the instrument display interface and platform can query historical alarms, collect alarm information, and display alarm curve graphs; Using sensors with fast response speed, high detection accuracy, low detection limit, long lifespan (up to 1 year of continuous operation for 24 hours), and reliable performance.

VOCs Mass Spectrometer is a scientific instrument specifically designed for rapid, highly sensitive, and selective detection and analysis of volatile organic compounds (VOCs) in the environment. It combines mass spectrometry (MS) technology with specific injection and ionization techniques, enabling qualitative and quantitative analysis of multiple VOCs in complex matrices, and even achieving differentiation of isomers.

1、 Application scope:

Environmental monitoring: used for online monitoring of VOCs in ambient air and water, capable of real-time detection of pollutant concentrations.

Traceability function: It has the ability to trace VOCs and odorous gases, and achieves precise positioning of pollution sources through high-performance time-of-flight mass spectrometer, pollution source fingerprint mass spectrometer library, and traceability model system.

Advantage:

No need for pre-processing: The sample does not require complex pre-processing steps and can be directly injected for analysis, saving time and cost.

High sensitivity: capable of detecting trace amounts of volatile organic compounds, suitable for environmental emergency detection and long-term monitoring.

Multi functional: Not only can it detect VOCs, but it can also detect odorous gases, suitable for various application scenarios.

2、 Core advantages and technological features

High sensitivity: capable of detecting trace VOCs at ppb (parts per billion) or even ppt (parts per trillion) levels.

High selectivity: Mass spectrometry provides a "molecular fingerprint" that can effectively distinguish between co effluent and interferents, reducing false positives.

Simultaneous analysis of multiple components: A single injection can analyze tens to hundreds of VOCs.

Strong qualitative ability: By comparing mass spectra and standard libraries, unknown substances can be accurately identified.

Quantitative accuracy: By combining standard samples and internal standard methods, precise quantification can be achieved.

Fast analysis speed: Especially with TOF and PTR technologies, real-time or near real-time monitoring can be achieved.

Performance characteristics of volatile organic compound (TVOC) monitoring system:

★ Adopting deep condensation dehumidification technology for pre-treatment of the tested gas drying to avoid pipeline blockage and protect other components of the instrument;

★ Adopting a multi-stage filtration system, combining primary filtration with high-efficiency filtration, to remove dust and particulate matter from the flue gas that clogs the pipeline, further improving detection accuracy;

★ Adopting imported diaphragm pump sampling technology, with high sampling accuracy, long service life, low maintenance rate, and reduced after-sales service costs;

The 7-inch large screen display highlights the humanized design, with real-time data curve graphs, historical data curve graphs, alarm statistics curve graphs, and instrument flow charts displayed intuitively, making it easy to analyze;

There are two options for 4G network wireless transmission and wired transmission (RS484 and RS232). The data is wirelessly transmitted to the platform or mobile app for remote control and setting, avoiding harm to monitoring personnel caused by toxic gases on the operation site;

The design of the sensor constant temperature module not only further improves the detection accuracy of the instrument, but also expands the working temperature range of the instrument to -40 ℃ -50 ℃;

The instrument has an alarm function for concentration exceeding the standard. Once the concentration exceeds the standard, the alarm light will sound and the interface will display an alarm. Both the instrument display interface and platform can query historical alarms, collect alarm information, and display alarm curve graphs;

★ Select sensors with fast response speed, high detection accuracy, low detection limit, long lifespan (up to 1 year for 24-hour continuous operation), and reliable performance;

The instrument has the functions of automatic zero calibration and manual cross calibration. Remote sensor calibration can solve the data drift caused by long-term operation of sensors, ensure data quality, shorten maintenance cycles, and reduce maintenance costs.
