Product features:
 
1) Efficient and reliable on-line collection technology of steam collision particulate matter (SIPS)
 
Innovative SIPS particulate matter online collection module, Based on the classical principle of nucleus condensation and growth of particulate matter, With the design of parallel long cavity and inertial cutting head, the target particulate matter is moisture-absorbed and grown efficiently to form a particulate matter suspension with higher enrichment ratio, which completely abandons the traditional filter membrane sampling technology, and can output the suspension containing the target particulate matter online, which has the remarkable characteristics of small residual effect and high collection efficiency.
 
2) Perfect dual-channel on-line microwave digestion technology
 
DMWS dual-channel microwave on-line digestion unit can completely digest 4 m3 or more particles in 10 min under the digestion conditions of 170 ℃ and 1.5 Mpa and the subsequent high-efficiency water cooling conditions. The dual-channel digestion unit realizes asynchronous operation and dual-channel switching operation, which fully guarantees the high time resolution requirement of online monitoring.
 
3) Innovative mixed dilution acid digestion system
 
This enables ICP-MS analysis without dilution on the premise of ensuring the digestion effect, and ensures the capture of silicon (Si) through high-efficiency water cooling technology, thus obtaining a complete digestion effect covering the full spectrum of target elements in the true sense.
 
4) Mature on-line dedicated ICP-MS unit
 
On-line special SUPEC 7000 ICP-MS is specially designed for on-line monitoring of inorganic elements. It is equipped with hydrofluoric acid-resistant injection system made of PFA material, which can easily tolerate the injection of atmospheric particulate matter sample solution in mixed acid medium. The analysis precision used immediately after torch lighting reaches RSD < 5%;
 
It has powerful collision reaction cell to eliminate mass spectrometry interference, simple operation, strong environmental adaptability, high degree of automation and stable and reliable analysis results;
 
Quality correction, detector calibration, quality interference correction, automatic tuning and other functions;
 
At the same time, it has qualitative analysis function, and unknown inorganic elements can be qualitatively identified;
 
It has the expansion function of pollution factors of other inorganic elements, and can measure more than 50 elements at most.
 
5) Strict data quality control
 
Adopt A-S-B-S mode to realize real-time calibration and realize accurate and reliable data quality control; It has the function of zero drift and range drift correction, analyzes the quality control samples at the same time as each analysis, and outputs the quality control data such as blank samples and quality control samples while outputting each monitoring data.
