Introduce Shanghai Aosong Scientific Instruments Co., Ltd. is a high-tech enterprise engaged in research, development, production and application of analytical instruments. Through continuous efforts, it has developed into one of the leading manufacturers of VOCs on-line detection system, gas chromatography, portable gas chromatography, On-line Chromatograph and gas generator in China. At the same time, the products have been extended to other scientific analysis instruments, as well as related peripheral equipment, software and accessories. And so on.

Products

AS-VOCs-5000
Volatile Organic Compounds (VOCs) online detection system is widely used in petrochemical industry, electronic industry, medicine, rubber products, organic solvent manufacturing, spray automobile manufacturing, printing and other industries. 1. Using imported switching valve, the maintenance is low and the service life is long; 2. Using slave column parallel reverse blowing technology to analyze the non-methane nephew can reduce the peak broadening and shorten the analysis time; 3. Using miniature FID detector, the sensitivity is higher than that of conventional FID detector; 4.19'standard cabinet, compact structure, can be integrated with the same type of instrument. Installed in vertical cabinet, it occupies a small area and is convenient for daily maintenance and operation. Built-in standard industrial PC, high-definition color makeup crystal touch screen, excellent human-computer interaction control software interface, based on Microsoft Windows operating system, can realize the automatic unmanned operation of the whole system. 5. Pitot tube differential pressure method is used to measure the travelling speed of organic exhaust gas; capacitance method is used to measure humidity; and the measurement signal is sent to the data acquisition and processing subsystem. The system has real-time field data transmission of xylene, styrene, acrylonitrile or methane, non-methane total binder implementation data and historical data. It has the function of remote fault diagnosis, and realizes the unattended wage field. 6. The whole system has simple structure, wide dynamic range, strong real-time, flexible networking and low running cost. At the same time, the system adopts modular structure and is easy to assemble. And it can communicate with DCS and data system of environmental protection department in enterprise. 7. AS-5000 VOCs fixed pollution source continuous monitoring system passes through the field for a long time.
portable gas chromatograph
Patented technology of central cutting plus back blowing is adopted, which meets the standard (H1013-2018). Direct toilet volume of methane and non-methane is always dazzling.
Specialized chromatographic column combination, sample 180X: thermal insulation, peak within 30S, no residue, high sensitivity;
The instrument has the functions of self-checking on start-up, gas-breaking protection, automatic restart of power-off and alarm to ensure the safety and quality of the system.
FID toilet detector has automatic ignition function and wide range output, linear range 10-7;
High repeatability and stability of carrier gas, air and hydrogen can be achieved by using high precision control valves.
The core components all use internationally renowned brands with high reliability and long service life.
GC-7890
Special chromatographic column, central cutting plus back blowing technology and FID technology were used for analysis. After the sample is filtered and collected into the quantitative ring, the sample valve is switched and separated into the column driven by carrier gas. The sample is detected by FID. The switch valve is reset, and other impurities in the pipeline are blown back and emptied. The chromatograph adopts American VICI rotor valve with small dead stretch, no moving parts, 1 million operation times without maintenance, low maintenance and long service life. Separation degree (> 1.55); metal capillary column or metal micro-filled column. It adopts the patent technology of central cutting plus back blowing, which meets the standard (H1013-2018); adopts special chromatographic column combination, 180C sample insulation, no residue, high sensitivity; the instrument has the function of self-checking, gas-breaking protection, automatic restart of power-off and alarm function to ensure the safety and stability of the system; Dynamic ignition function and wide range output, linear range of 10-7; high repeatability and stability of carrier gas, air and hydrogen can be achieved by using high-precision control valves; core components are using internationally renowned brands, high reliability and long service life.
GC-7890-II
GC-7890-II gas chromatograph is developed by Shanghai Aosong Scientific Instruments Co., Ltd. on the basis of many years of chromatographic manufacturing experience and modern instrument manufacturing technology. It has excellent performance, complete functions and convenient use.
