The company was established in 1993 and is a professional physical and chemical analytical instrument manufacturing enterprise integrating scientific research, research and development, production, sales and services. The company has strong R&D strength, excellent R&D team, and support from professional R&D cooperation institutions. Since the founding of the company, we have continuously introduced talents, built a professional experimental technology platform, and continuously promoted systematic scientific research.

In 1995, the EP-100 series of ion chromatography instruments was launched, and 20 units were sold in the same year; in 1997, the domestic ultra-pure water device was launched; in 1998, the EP-100 was upgraded to EP-200, and the number of ion chromatography users exceeded 100. In 2001, laboratory silicate and phosphate detectors were launched; in 2005, variable wavelength ultraviolet detectors UV-100 and UV-200 were launched; in 2006, two ion chromatographs, EP-1000 and EP-2000 were launched.

In 2010, commercial portable ion chromatography was launched. In 2013, we began to customize a special ion chromatograph for the Institute of Atomic Energy to detect condensate water for nuclear reactors; in 2014, we began to develop an online ion chromatograph based on customized instruments for the Institute of Atomic Energy; in 2015, we completed the first online ion chromatograph for EP-7000. , provides Xinjiang Public Security Bureau with multiple portable chromatography for detection.

In 2017, it provides a portable ion chromatograph for my country's aircraft carrier "Shandong"; in 2018, it completes the development of online carbon dioxide instruments for seawater acidification; in 2019, it completes the automatic syringe based on ball screw rod type, intelligent high-pressure 8-way valve, intelligent high-pressure 6-way valve, intelligent Medium pressure 3-way valve to intelligent medium pressure 10-way valve and achieve mass production; complete the research and development of multi-functional and modular EP-6000 series chromatographs and formal mass production in 2020; complete the design and development of flow injection and new pure Water appearance.
