product overview
The Mars-400 Plus portable gas chromatography-mass spectrometer (GC-MS) is an analytical instrument that uses a built-in battery and carrier gas, operated by a single person, and can accurately perform qualitative and quantitative analysis in harsh accident scenes. This instrument combines low heat capacity gas chromatography technology with ion trap mass spectrometry technology, fully leveraging the advantages of fast gas chromatography in terms of analysis speed, high separation efficiency, strong qualitative ability, and high detection sensitivity of mass spectrometry. It can accurately and quantitatively detect organic pollutants at accident sites in a timely and rapid manner, and is mainly used for on-site analysis of volatile and partially semi volatile organic compounds in environmental air, water bodies, soil, and solid waste.

On site analysis has put forward strict requirements for the comprehensive performance of the instrument. As an advanced portable GC-MS, Mars-400 Plus is not only stable and reliable, with strong environmental adaptability, but also has significant technical advantages in analysis speed, detection sensitivity, sample introduction method, portability, and other aspects:
Fast analysis speed: A combination of rapid gas chromatography technology and ion trap mass spectrometry high-speed scanning mode is adopted, which shortens the analysis cycle to less than 20% of conventional chromatography, thereby improving the analysis efficiency by more than 5 times compared to conventional gas chromatography technology;
High detection sensitivity: A three-dimensional ion trap is used as the mass analyzer for Mars-400 Plus, and a patented pulsed internal ion source technology is developed to improve the system's response to low concentration components and meet the high sensitivity detection requirements for trace samples on site;
Flexible measurement methods: The instrument is equipped with a built-in split flow inlet, gas sampling probe, and headspace sampling system to detect environmental samples in three forms: gas, liquid, and solid. Handheld gas sampling probe is used for on-site gas sample sampling; The headspace sampling system is used for on-site analysis of volatile organic compounds in water and soil, with two sampling modes: static headspace and dynamic purge; Solid phase microextraction (SPME) injection or direct micro liquid injection can be achieved through a split injection port. SPME injection can be used for sampling and injection of volatile and semi volatile organic compounds in water and dissolved solid samples, which can enrich target substances, remove matrix interference, and effectively improve detection sensitivity; Direct injection analysis of organic solvents can be performed using microinjectors; The use of gas sealed injectors can directly inject and analyze high concentration VOCs emitted from pollution sources, quickly obtaining analysis results;
Excellent portability: Through integrated technology research, miniaturization, and seismic design, the instrument's main body weighs less than 19 kg and can be carried by a single person to the accident site in a timely manner;
Easy to operate: The analysis software of the instrument converts the basic operations in the sample analysis process into an intelligent "guided" operation mode, using a graphical operation interface and a touch LCD screen for human-computer interaction, reducing the complexity of on-site operations.
