First bipolar membrane ion chromatography system introduced

The Bipolar Membrane Ion Chromatography System (Reagent-Free, Non-Degassed RGFICTM) introduced by Anhui Puyi Science and Technology Co., Ltd. was first introduced on the 8th National Ion Chromatography Conference on September 8, with bipolar membrane ion chromatography. The system is the first application of bipolar membrane technology in the field of ion chromatography. This technology breaks the monopoly monopolization of foreign manufacturers in the field of “elution fluid autogenesis” and at the same time theoretically solves the problem of the traditional “electrolyzed water” eluent automation. The occurrence of technology needs to increase the disadvantages of degassing equipment. In this way, China's ion chromatography theory is back in the world. The traditional eluent generation technology uses hydrogen ions and hydroxide ions produced by “electrolyzed water”. The equation is: Anode: 2H2O—>4H++O2 Cathode: 2H2O—>2OH—+H2 ​​Gas generation requires degasification equipment. Bipolar membrane ion chromatography uses bipolar membrane "dissociation water" to generate hydrogen ions and hydroxide ions. The equation is: H2O-->H++OH- does not produce gas. The ion chromatographic system theory of "Reagent-Free-Ion-chromatography" has received a strong response from the participants.

Ion chromatography is recognized as the "gold analysis method" for analyzing anions in the world today. It is widely used in food safety, environmental protection, national defense anti-terrorism, nuclear industry, power electronics, semiconductors, military industry, petrochemicals, geological prospecting, life sciences, agriculture Plant protection and many other fields, but also in the cation analysis, also has an important position, especially in the field of inorganic cation valence analysis, has an irreplaceable use.

At present, in the field of ion chromatography, a well-known international brand of ion chromatography has its absolute global market share in China, thanks to its unique patented global technology, RFIC Regent Free Ion chromatography. It is still firmly controlling the high-end market of ion chromatography, and domestic manufacturers have been in a slight trend due to lack of theoretical innovation and relatively weak research and development power.

According to Dr. Zhang Chenguang of Puyi Technology Research Institute, due to the introduction of ultra-pure water into the system and the principle of “electrolyzed water”, the traditional eluent generation technology will generate the “elution fluid” necessary for the work of the ion chromatography system, thereby increasing the The instrument's performance. However, the "electrolyzed water" theory generates "eluent" and gas will enter the "eluent", the gas has a serious impact on the quality of the "eluent", in order to eliminate the impact, the need for complex degassing device The gas is removed, and the degassing device cannot absolutely remove the gas in the high-pressure eluent. Therefore, reducing the quality deterioration of the eluent by the gas has always been the goal pursued in the field of ion chromatography. Bipolar membrane technology has been introduced in recent years. The new technology, Funeral Co., smartly uses the bipolar membrane's "hydrolysis separation" function, combined with reasonable structural design, completely avoids the generation of gas during the "eluent" generation, thus eliminating the need for a complex degassing system. Improve the reliability of the system.

It is understood that the use of Bipolar Membrane Technology's IC6000 series bipolar membrane ion chromatography system is developed at home and abroad for the needs of high-end products, due to the use of bipolar membrane technology, not only can complete the existing automatic washing All the functions of the liquid generating equipment, but also saves the degassing equipment, greatly enhances the reliability of the system and reduces the operating costs. In addition, Puyi IC6000 series is also fully compatible with existing "electrolytic water" reagent ion chromatography system consumables, its core indicators have completely reached the international advanced level.

comment:

For many years, the academic activity of ion chromatography in China has been very active. There is no obvious difference with the foreign countries in the development of the theory. However, due to the weak industrialization in China, the loss in international competition is not small. For example, the membrane suppression technology proposed by the academician Tian Zhaowu of Xiamen University in 1983 was much earlier than the membrane suppression technology proposed by the US Dian Company in 1992. However, due to the backwardness in the conversion of domestic scientific research achievements and the backwardness of intellectual property protection at the time. , which makes Daian Company exclusively own this product on a global scale.

The introduction of the bipolar membrane ion chromatography system once again enabled domestic ion chromatography to reach the international advanced level in the academic field, and made an important step for domestic instruments to move toward the world as soon as possible.
