Chongqing University Launches Analysis Services using CIQTEK EPR200-Plus Spectroscopy

After a trial run of more than one month, the Analysis and Testing Center of Chongqing University officially launched its electronic paramagnetic resonance (EPR) related analysis and testing services to the society on September 6th, 2021. The EPR (ESR) spectroscopy they used, CIQTEK EPR200-Plus, is the first commercial X-band continuous wave EPR (ESR) spectrometer in China, with several self-developed core technologies and breakthroughs in key performance indicators.       Professors from the Analysis & Testing Center of Chongqing University used CIQTEK EPR Spectroscopy for testing services   EPR (ESR) technology is the only device that can directly detect the presence of unpaired electrons and can be used for the characterization of materials containing unpaired electrons, metal valence, vacancy, free radicals detection, etc.    Based on CIQTEK EPR200-Plus, Chongqing University Analysis and Testing Center can provide analysis and testing services for scientific research in the field of environmental science, materials physics, biomedical, chemicals, industrial science, food industry, etc. The service capability and technology have also been enhanced to provide technical support and high-quality services to universities and social science institutions.   CIQTEK EPR200-Plus at Analysis & Testing Center of Chongqing University   Chongqing University is a high-level research comprehensive university built by the Chinese Ministry of Education. Its Analysis and Testing Center is a public testing platform for large instruments and equipment open to society, dedicated to playing the role of the university-level public platform to support scientific research services.   Analysis & Testing Center of Chongqing University   CIQTEK always insists on serving scientific and technological research. In this cooperation, CIQTEK has given full play to its technical advantages to help the long-term development of scientific research platforms in universities, promote the open sharing of scientific resources, and provide effective support for the implementation of the innovation-driven development strategy.      "When choosing the brand and model of EPR spectrometer, we conducted a six-month measurement sample comparison and found that the effect and service experience of CIQTEK EPR measurement was the best. After an in-depth study, we found that CIQTEK EPR spectroscopy is comparable to imported brands in many key performance indicators, and some of them are even better than others, which can meet our needs in large scientific instruments. At the same time, the rich industry application solutions and perfect after-sales service of CIQTEK also impressed us." Zhou Xiaoyuan, director of Chongqing University Analysis and Testing Center.     CIQTEK EPR (ESR) Spectroscopy   Originating from the Key Laboratory of Microscopic Magnetic Resonance of the Chinese Academy of Sci...

Happy 2024 Lunar New Year

On February 2, CIQTEK 2024 Chinese New Year Annual Meeting was successfully held, sharing the fruitful results of 2023. In 2023, CIQTEK will continue to innovate pragmatically, promote the industrialization of technology and the localization of high-end scientific instruments, and launch a new spin magnetometer, focused ion beam electron beam dual-beam electron microscope, ultra-high resolution field emission electron microscope, high-speed scanning electron microscope, and other domestic high-end scientific instruments. The electron paramagnetic resonance spectrometer has the first domestic market share; the annual turnover of the electron microscope is nearly 200 units, exceeding the total of other domestic brands; the oil near-drill follow-drill measurement instrument has completed more than 200 wells operation service in shale gas, conventional coal bed methane, deep coal bed methane, and other areas, leading the business segment market. In addition, the Specific Surface and Pore Size Analyzer series and Electron Paramagnetic Resonance Spectrometer products helped publish 51 high-level research results.

CIQTEK Received a Thanks Banner from the MR Lab of Tsinghua University Analysis Center

In December, CIQTEK received a special gift, a thanks banner from the Magnetic Resonance Laboratory of Tsinghua University Analysis Center. A thanks banner is a traditional way to show thanks and gratitude in China.       In November 2019, an electron paramagnetic resonance (EPR or ESR) spectroscopy in the Magnetic Resonance Laboratory of Tsinghua University's Analysis Center failed to measure the signal. After the discussions, the team decided to ask CIQTEK team for help. As the company with advanced EPR (ESR) spectroscopy technology, CIQTEK has the strength of independent research and development of EPR (ESR) instruments and professional service & support team. After arranging for engineers to visit the site, the EPR spectroscopy in the MR lab was able to detect the signal again after troubleshooting and maintenance.     According to the feedback from the magnetic resonance laboratory of Tsinghua University Analysis Center, the same test conditions of manganese standard signal was the same as before the repair after the end of the repair and turn-on test (Figure 1); restart the instrument, the test was normal (Figure 2); adjust the field amplitude increased to five times, the signal intensity expanded to about five times (Figure 2); the manganese standard signal could be measured at different modulation frequencies. A fullerenes sample, the test is normal.   It is reported that the EPR (ESR) spectroscopy was unable to measure the signal due to the damage of the modulation field system. For such problems, the CIQTEK EPR (ESR) engineers took only 4 working days from on-site inspection to restoration of the test, which greatly relieved the testing pressure in the laboratory and met the testing needs of the students and teachers.   Since its inception, CIQTEK has been committed to helping our customers more efficiently promote the development of technology and explore the future of mankind. We take "first-class products, first-class service" as our aim, and always insist on customer first. Establishing excellent brand service is our constant pursuit.   The Magnetic Resonance Laboratory of Tsinghua University Analytical Center wrote in the banner, "The maintenance work of EPR spectroscopy is professional, timely and reliable, setting standards for instrument industry." CIQTEK is honored to receive such high praise, and will continue to work hard and contribute to the revitalization of the high-end scientific instrument industry.     Tsinghua University Analysis Center The Department of Analytical Chemistry at Tsinghua University was established in 1926 as one of the key "specialties" at the beginning of the Department of Chemistry. "In 1985, Tsinghua University resumed the establishment of the Department of Chemistry, and the former Analytical Chemistry Department and Tsinghua University Analytical Center were integrated into an entity combining teaching, research, and service.     Note...
