Since the company was established, Puren staffs persist in the pursuit of " Innovation, Quality, Integrity and Service ". All our products have independent intellectual property rights. The improvement of current products and the research of new products never stop in order to better respond to customers’ needs. Moreover, collaborations with universities and scientific research institutions still increase to make sure that our products could provide leading performance in a variety of areas.

Now Puren series of ion chromatographs (PIC) are widely used in drinking water detection, environmental protection, agriculture , quality inspection, disease control, chemical, petrochemical, universities and scientific research institutions, etc. Following the steady growth in the market, Puren products are sold nationwide in over 32 municipalities, provinces and autonomous regions, and are exported to overseas market.

As a high-tech enterprise,Puren always works on applying new technologies to new products. PIC-online ion chromatography system, supported by the National Innovation Fund, is the first product in domestic market with independent intellectual property rights. In 2015, this instrument was equipped into icebreaker Xuelong (Snow dragon) for an Antarctic scientific expedition, which continuously worked over three months and obtained enough scientific data under various climatic conditions successfully. In 2007, Puren firstly demonstrated its dual-system ion chromatograph to the market.This dual-system IC has effectively overcome the mutual interference between two systems in one integrated structure, which could deliver the detection of anions and cations simul-taneously, and achieves gradient elution. In 2002 the voltammetric cell was made, with a wide lead over its domestic competitors at that time. It is used for analyzing various anions, cations and organic compounds, for example bromide, iodide, sulfide, cyanide, etc. (anions) and lead, copper,zinc, cadmium, etc. (cations) and even carbohydrate or amino acids. Puren also possesses patents related to exclusive IC Auto-sampler and Automatic precipitation sampler and provides these products for customers to simplify workflow.

As our slogan, Puren staff will always work on self-innovation, improve product quality, focus on customers’ demands and provide excellent customer service. We will dedicate ourselves to the glorious future of national ion chromatography industry, with suggestion and help from experts and customers.
