In recent years, bisphenol analogues such as Bisphenol S (BPS) have come to replace bisphenol A in food packaging and food containers, since bisphenol A (BPA) has been shown to leach into food and water, causing numerous negative health effects.Bisphenol compounds are found throughout the contemporary world in the form of plastics that are used extensively by consumers for food storage. These polymers are also widely used in the packaging of baby formula, baby bottles, the lining of canned food and drink, dental implants, and sales receipts. Mainly though, these particular plastics enter the diet when people microwave food in plastic food containers or eat and drink from plastics that have been exposed to much wear or harsh chemicals that break down the monomers and release them into the food or drink. 4,4'-Sulfonyldiphenol,Pink Crystal Powder,4 4-Sulfonyldiphenol Cas 80-09-1,Sulfonyldiphenol Chemical Polymer Jiangxi Hongjiu New Material Technology Co.,Ltd. , https://www.hongjiutech.com
The core component infrared detection pool uses high-efficiency, long-life noble metal micro-infrared light source and metal mirror; the modulation system uses a high-precision stepper motor controlled by a single-chip microcomputer to achieve long-term stability of the modulation frequency, combined with infrared heat release at the international advanced level. Electron solid cone sensors, narrowband filters, detectors, etc. The proprietary components and high-accuracy A/D sampling cards of the Shanghai Institute of Technical Physics of the Chinese Academy of Sciences (CAS) enable extremely high detection sensitivity and can effectively detect ppm levels of carbon. Sulfur content.
Infrared carbon-sulfur analyzer is used to analyze the carbon and sulfur content in the material by detecting the absorption of infrared radiation by CO2 and SO2 gas. Linearization calibration is a key technology in instrument data, because Lambert's law is in line with the law of the index. The infrared filter has a certain bandwidth, and the gas absorption coefficient is not a constant, so it is very difficult to obtain the linearization of the integral area. We have made major breakthroughs in the design of calibration mode, calculation method, and calibration software and are superior to the best instruments in foreign countries. We have achieved good linearity in the full range. Our domestic counterparts almost use multi-air chamber segmentation calibration. Therefore, there are great disadvantages and limitations in use.
Infrared Carbon and Sulfur Analysis Instruments Based on the original infrared carbon-sulfur analyzer, the company first adopted a frequency-adjustable infrared xenon light modulation system, and the circuit signal processing was further optimized, so that the influence of background interference on the detection signal was minimized. To ensure product performance. So as to ensure the high performance of the whole machine detection analysis. Finally, optimization and integrated design are used to improve work reliability and anti-jamming capability, and cost-effectiveness is improved so as to better meet the needs of different users. 
The infrared carbon-sulfur analyzer has been widely popularized and popularized. It has a good platform to improve the application scope of the instrument and the accuracy of the analysis results. It can be widely used in various black and non-ferrous metals and non-metals such as steel, copper and aluminum and their alloys. The analysis of carbon and sulfur content in materials can better meet the needs of analysis and control of carbon and sulfur elements in various materials in the fields of metallurgy, machinery, and chemical industries in front of furnaces, finished products, and incoming materials.
