In 1983, China's first domestic ion chromatograph was born. Over the past 30 years, ion chromatography has made tremendous contributions to China's national economic construction. On July 19, 2013, sponsored by the Analytical Instrument Branch of the China Instrument and Control Society, Qingdao Shenghao Chromatography Technology Co., Ltd. hosted the “China Ion Chromatography 30th Anniversary Commemoration” in Qingdao. More than 200 experts and scholars, engineers and technicians from various parts of the country, representatives of application fields, and authoritative media from the industry gathered together to review our progress in ion chromatography from scratch and from being to excellence; AC ion chromatography Instrument research, development, manufacturing and application of advanced technologies; jointly explore the development direction and prospects of domestic ion chromatography.

At the beginning of the meeting, Xia Zhengqi, deputy head of Laoshan District, delivered an opening remarks. The mayor of Xiashan first extended a warm welcome to all the experts and scholars for their visit to Laoshan, and congratulated China on the 30th anniversary celebration of ion chromatography. He said: Qingdao Shengyu Technology Co., Ltd. is a very famous enterprise in Qingdao. It is very good in the management of corporate culture and is also a representative direction of industrial development. The commemoration of the 30th anniversary of ion chromatography in China today was held. Ion chromatograms were held together with the elites of the elders to discuss the development of our ion chromatograph. By studying the development direction of ion chromatography, we will surely gather and develop the ion chromatograph industry in Shaoshan. To actively promote the role.

Academician Hou Baorong first expressed heartfelt congratulations for the holding of the 30th anniversary of ion chromatography. He mentioned that some instruments and equipment are also used in peacetime, but it is the first time that such equipment and equipment have participated in meetings. Previously there was not much communication with everyone in this area. Little is known. Just listened to the Director and the Secretary General introduced the ion. He was very honored to experience the development of chromatography. The development of ion chromatography in our country over the past 30 years has achieved very good results. He sincerely thanks Liu Kailu and other 5 old Chinese founders of ion chromatography for their pioneering work in the ion chromatography industry in China and continued to just now.

In the past 30 years, ion chromatography has developed very well. The younger generation did not disappoint the expectations of these old gentlemen. Currently. Many of China's equipment and equipment rely on imports, but ion chromatography is indeed on the front, achieving its own design, production, and development. This is a feature of China. This is a big bright spot. Academician Hou said: The work of ion chromatography has opened a very good head for the development of Chinese instruments. We must learn the spirit of the old comrades' founding business, develop all the other instruments of our country, and realize the localization of our instruments. It is the direction of our research. Although commemorating the 30th anniversary of ion chromatography today, it actually provided me with a good opportunity, opportunity and role model for the development of experimental equipment and instruments. Finally, Academician Hou expressed his congratulations on the meeting. At the same time, he once again expressed his gratitude to several old gentlemen and raised hopes for the future development of the Analytical Instrument Society. He believes that the future work of analytical instruments will surely do even better.

Academician Zhang Yukui of the Dalian Institute of Chemical Physics, Chinese Academy of Sciences sent a letter of congratulation for the 30th anniversary of ion chromatography in China. In his letter, Academician Zhang expressed his warm congratulations on the convening of the conference. He said Qingdao is the birthplace of China's ion chromatography industry. In 1983, the first domestic ion chromatograph was successfully developed at Qingdao Laoshan Electronic Instrument Laboratory. After 30 years of development, a series of ion chromatographs have been developed and applied in food safety, environmental protection and other fields, laying the foundation for the sustainable development of ion chromatography in China and becoming an important part of the development of chromatographic instruments. Academician Zhang hopes to further strengthen the production-study-research-use development model in the future to improve the core competitiveness and promote the development of the ion chromatographic instrument industry in China.

Due to weather-related delays in flight, Guan Yafeng, director of the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, came to the meeting at noon, so he did not catch the opening ceremony and sent a congratulatory letter in advance. Teacher Guan indicated that in 1983 China's first ion chromatograph was successfully developed at the Laoshan Electronic Instrument Laboratory in Qingdao. In the following 30 years, after a long period of hard work and hard work by IC, we developed and commercialized a series of ion chromatographs, which have been widely used in the field of environmental protection and laid the foundation for the sustainable development of ion chromatography in China. In 2012, the Ministry of Science and Technology's scientific instrument major project supported the ion chromatograph project. In order to improve the core competitiveness, promote the development of the ion chromatography equipment industry in China and achieve a healthy increase in production-study-research-use, substantial support was given.

Chairman Zhu said: There are three main purposes for Qingdao Shengyu to host such an event. Thanks to Chairman Zhu for representing the company and the industry’s employees, Liu Kailu and other teachers thanked the 5 teachers for putting China’s first ion chromatography in July, 83. Successfully developed, it is their foundation that made the industry of ion chromatography develop; Innovation: After 30 years of hard work and development, Ion Chromatography has made some progress and innovation. This conference will introduce some technical achievements and some technical lectures, and Share with everyone; 3. Oath: It is a very short moment to start an association for 30 years in history, but for life, the whole work is for the rest of my life. At present, China-made ion chromatography, analytical instruments, and domestic ion chromatography products account for only 20% of the entire industry and the market. Sheng Yu feels a heavy responsibility, but Sheng Yu has the responsibility and ability to do a good job of ion chromatography products. In the future, the product precision of Shengyu will increase and it will become a stable international market. The future of ion chromatography in China is promising. Through the commemoration of the 30th anniversary of China's ion chromatography, as the industry's employees and corporate personnel, Sheng Hao is willing to do a good job in this industry. Subsequently, the unveiling ceremony for the construction of Qingdao Ion Chromatography Engineering Research Center was held.

Professor Liu Kailu, professor-level senior engineer of the Beijing Institute of Chemical Industry and Metallurgy, Ministry of Nuclear Industry reviewed the development of ion chromatography in China. Liu Kailu said with emotion: In the fall of 1981, he met Dionex's Dionex14 ion chromatograph for the first time at the multi-national instrument exhibition held in Tianjin. It can well solve the urgent need to solve the micro-multi-component anion in China. Analysing the issue caused great interest from Liu Kailu and many visitors. However, a Chinese-American manager of the company said arrogantly: “This is the latest achievement of DOW Chemicals scientists. You will not come out in decades.”

This sentence deeply stung the heart of Teacher Liu. That night, Teacher Liu could not sleep at night. After coming back, he plucked through the literature and analyzed it carefully. It was at that time that a Chinese ion chromatography development plan was formed in his mind. Now. With the help of Deputy Director Dong Lingying, Ionic Chromatography Separation Columns, Suppression Columns, Conductivity Detectors, etc. were trial-produced with only 20,000 yuan in funds. In 1983, the first ion chromatograph ZIC-1 ion was developed in China. Chromatograph, through departmental appraisal.

In 1983, the first ion chromatograph ZIC-1 ion was developed in China. Chromatograph, through departmental appraisal.

After the successful introduction of the ZIC-1 ion chromatograph, Liu Kailu was not satisfied. In order to keep pace with the world's ion chromatography, he also conducted a series of creative research work. In 1982, 1986, and 1989, he won the science and technology progress award for the nuclear industry three times, the second prize for scientific and technological progress in Qingdao in 1987, and the third prize for state-level scientific and technological progress in 1991.

In 1986, Liu Kailu theoretically studied the principles of the existing ion suppression chromatographs and single-column ion chromatographs in the world, and deduced the detection lower limit formula for the two modes.

In 1987, Liu's wife Yuan Siming developed a highly efficient cation separation column to achieve cation analysis of domestic instruments. Zhao Yunxi and Su Chengyuan developed a five-electrode conductivity detector. Based on this, Liu Kailu, Zhao Yunshen, and Su Chengyuan jointly developed. ZIC-2 and ZIC-2A dual mode ion chromatographs. Later, Liu Kailu successfully developed a continuous self-regeneration type high-efficiency ion exchange device and obtained a Chinese patent (patent number: ZL00201227.8). In this regard, Liu Kailu said, “This is an ion chromatography technology that we Chinese created, and it turns out that this technology has been widely used in China, making China's ion chromatography develop rapidly in the 21st century.”

Professor Liu Kailu also said that the ion chromatography column is very crucial. He originally intended to develop the ion chromatography packing, but his heart is not enough. Fortunately, currently Shenghao Chromatography is working hard on this aspect, said Liu. "Thank you for Chromatography for introducing a new ion chromatography column, or we always retired." This simple sentence not only affirmed the efforts of Shengjing Chromatography over the years, but also showed the responsibility of the old generation of chromatographers. And persistence, let us have to move.
