In response to the time-consuming source tracing of volatile organic compounds (VOCs) pollution and the difficulty of real-time and accurate analysis of multi-component substances, Spectrum Technology has developed the 7000 high-sensitivity, high-reliability, soft-ionization proton transfer reaction time-of-flight mass spectrometer using a dual-anode hollow cathode discharge source and vertically introduced reflective time-of-flight mass spectrometry technology. The 7000 has outstanding features such as fast analysis speed, high sensitivity, strong qualitative ability, and a wide range of measurement components. It is suitable for cruise monitoring and online monitoring of VOCs in parks.

DESCRIPTION

Performance advantages

A wide variety of substances to be detected

Water is used as a reagent molecule, which has a broad spectrum of ionization capabilities and can meet the monitoring of most VOCs substances in ambient air.

Low detection limit

Sub-ppb detection limit, lower than the national standard emission limit of most VOCs.

Accurate qualitative and quantitative capabilities

Soft ionization technology, when measuring trace VOCs in the air, is not interfered by conventional components in the air, and does not require sample pretreatment. The target product is mainly hydrogenated quasi-molecular ion peaks, the spectrum is simple and easy to identify, and the target is accurate in qualitative and quantitative analysis.

Professional anti-seismic design

The whole machine has passed the vibration test to ensure the stability and reliability of the instrument, which is suitable for cruise monitoring under complex road conditions.

Intelligent operation design

Adopting fully automatic intelligent control software, Chinese interface, the instrument status is clear at a glance, with self-diagnosis, self-protection, pressure and temperature self-compensation, and one-button automatic operation functions, opening the era of unattended operation.

PUYU Technology

Application fields

Fixed-site continuous monitoring

7000 can monitor the changes of VOCs in air, water and fixed pollution sources in real time, and establish a fully covered distributed monitoring and early warning system with it as the core. It can realize the source control of key control factors in the park and pollution early warning in sensitive areas.

PUYU Technology

Cruise monitoring

Cruise monitoring analyzes the temporal and spatial changes of VOCs in ambient air in real time, locks the source of pollution, and provides accurate data support for the decision-making of law enforcement departments.
