ã€Research and Development of China Instrument Network Instrumentation】 Recently, the research results of the “Vacuum Hydrogen Peroxide Sensor Calibration System†project carried out by Zhejiang Institute of Metrology successfully solved the technical difficulties of measurement data deviation of Tailin Biotechnology Co., Ltd. and ensured the enterprise's over-oxidation. Hydrogen measurement accuracy and traceability.
The “Vacuum Hydrogen Peroxide Sensor Calibration System Study†was established by the Zhejiang Provincial Bureau of Quality and Technical Supervision and undertaken by the Zhejiang Institute of Metrology, among which the Senior Engineer Chen Zhemin of the Zhejiang Institute of Metrology Sciences was responsible for the construction of the CRDS device and the engineer Pan Sunqiang was responsible for the overall system design of the system. Fang Daguang is responsible for experimental measurements and Lin Biao is responsible for traceability; Xia Xinqun, a senior engineer of Hangzhou Tailin Biotechnology Equipment Co., Ltd., is responsible for the design and development of hydrogen peroxide generators. The division of labor is clear, ensuring that the project has been implemented since September 2014 and has progressed smoothly.
In the "Research on Gas-phase Hydrogen Peroxide Sensor Calibration System", the working group conducted research on hydrogen peroxide concentration monitoring device based on mid-infrared TDLAS. The working characteristics of the 8mm quantum cascade laser are understood, and the effects of the time constant of the lock-in amplifier, the modulation frequency and the modulation depth on the second harmonic signal are studied. On this basis, suitable parameters were chosen to measure hydrogen peroxide with a detection limit of 2.31 ppm. At the same time, the experts carried out studies on the occurrence characteristics of hydrogen peroxide generators. The flow rates of hydrogen peroxide solutions were set to 0.5 g/min, 1 g/min, 1.5 g/min, 2 g/min, and 4 g/min, respectively. The TDLAS hydrogen peroxide concentration monitoring device monitors the hydrogen peroxide concentration and the generated hydrogen peroxide concentration stability is less than 1.5% with a concentration range of 160 to 1076 ppm. In the experiment, a potassium permanganate titration method was used for hydrogen peroxide concentration monitoring device calibration, with a slope of 43.534 ppm/mV and R2 of 0.99947.
This time, the Zhejiang Metrology Institute successfully solved the problem of Tai Lin Biotech Co., Ltd. through the “vaporized hydrogen peroxide sensor calibration device.†Zhejiang Tailin Biotechnology Co., Ltd. is the largest company in China and the earliest company to develop a vaporized hydrogen peroxide sterilization system and a sterile isolation system. The company's hydrogen peroxide concentration measurement mainly uses imported hydrogen peroxide electrochemical detectors. However, there are problems such as inconsistent measurement data from multiple detectors, aging of the detector, and measurement data deviation.
Faced with the situation, the company actively sought the help of metrology agencies and began to develop its own technology in an attempt to break the current situation. In June of this year, the company's "Development and Application of High-Performance Intelligent Sterility Tester" project was successfully selected as a national key R&D project. The project has a total of 8 sub-topics, centering on a major domestic strategy for food and drug safety, aimed at solving the current national bottleneck in the development of high-performance intelligent food and drug aseptic testing and development to further improve the overall level of domestic food and drug safety. This is an affirmation of the company's ability to innovate, and it also promotes the process of localization.
