Summary
SH-GIC7000 on-line ion chromatography monitoring system for atmospheric particulate matter and gas components solves the above problems well. The monitoring period is adjustable, and the sampling period is no more than 1h. Once the solution is replaced, the sustainable and stable work is greater than 720h. The eluent generator technology is simple to operate, only need to regularly add deionized water can work continuously, maintenance-free, high degree of automation, saving time and labor, is a powerful tool for the monitoring of particles in the air and ion components in the gas. The small-diameter ion chromatography column independently developed by Shenghan has a low flow rate, which reduces the consumption of reserved deionized water, and the service life of deionized water with the same volume is longer.
Functional advantage
1: Continuous cycle detection of the concentration of atmospheric particles and cations in gases
2: Reliable aerosol and gas dissolution separation technology and absorption technology
3: Independent intellectual property rights of cation separation detection technology
4: National certification of 720 consecutive hours of long running test
Component introduction
1: PM2.5 cutter
The atmosphere passes through the PM2.5 cyclone cutting head with a flow rate of 16.7L/min, and the aerodynamic equivalent diameter is greater than 2.. 5um of particulate matter. Teflon is used to collect gas samples in a straight line to reduce the loss of aerosols and gas components in the process
2: dissolution device
Self-developed ceramic corroder, in which gaseous pollutants enter the absorption liquid and react with it to complete the absorption of gaseous pollutants. Rough surface coatings and collected contact area increase. Channel straightening effectively prevents particle enrichment in annular dissolver. The metal jacket can effectively prevent the corrosion device from stress fracture, more durable.
3: particulate matter catcher
Ultrasonic atomization technology, the use of high frequency resonance will disperse the liquid water molecular structure to produce natural floating water mist, in addition, in the atomization process will also release a large number of negative ions, so that the water mist more effectively "capture" solid particles, water mist into the collection tank collection, the injection pump will inject the liquid into the cation detection channel for detection. The atomization process does not require heating and pressure, and the atomized particles are small and the capture efficiency of particles is high.
4: Suppressor (self-regenerative electrolytic microfilm suppressor)
The suppressor uses electrode hydrolyzed water to produce H+ and OH-, and realizes ion directed migration and exchange under the combined action of electric field and ion exchange membrane to complete the inhibition effect. The background conductance can be reduced by suppressor. Improve the sensitivity of the ions to be measured, so that the "counter ions" in the sample into the waste solution.
Anion inhibition function: compatible with carbonate, hydroxide system and other common anion systems; Cationic inhibition function nitric acid, methanesulfonic acid and other systems of advanced continuous self-regenerating micro film electrical inhibition technology, without additional regeneration liquid; High inhibition capacity, low background conductance; Low noise, good stability, accurate data;
Pollution resistance, high pressure resistance, long life; Compatible with 100% organic solvent; Can match domestic and imported ion chromatography products of the same type; The signal line is connected by aviation interface, convenient disassembly and assembly;
High pressure resistance, no leakage in the case of up to 6MPa; Normal operation at 2MPa, improve the compatibility of combined detection technology and column switching technology;
5: chromatographic separation system
Shenghan Company is the only ion chromatographic column manufacturer in China. Independent research and development of Yin, cationic column, high efficiency, stable performance; High voltage resistance, compatible with 100% reversed-phase organic solvent; Fine diameter column, less flow, the same eluent bottle can more than double the use time. Excellent performance, stable polymer stationary phase; Complete batch tracing and reproducibility; Strong versatility, can be widely used in domestic and imported brands of ion chromatograph.
6: eluent generator
The eluent generator is the core technology of the new generation of reagent free ion chromatograph. The instrument realizes the function of generating the required concentration eluent online only through pure water. It avoids time-consuming operations such as making eluent manually, greatly improves the degree of automation of analysis, and avoids testing errors caused by human factors. At the same time, the intelligent control mode can realize the customization of eluent concentration, and can realize the gradient elution separation operation of complex samples which can not be completed by the previous equal degree pump, and further improve the accuracy of analysis.
7: low temperature standard liquid storage unit
Instrument built-in low temperature standard liquid storage unit, storage series concentration of Yin and Yang ion standard solution, can be set according to the demand time interval, automatic standard curve testing and calibration. Low temperature and constant humidity environment to ensure that the standard liquid long-term deterioration, a replacement of standard liquid, sustainable use for 60 days.
