EX1600 analysis system, a good helper of your laboratory analysis, is a high performance liquid detection system, suitable for most of sample testing from simplicity to complexity, and unit components can be changed according to users' demands.

●  Stabilization

The high-performance reciprocating parallel pump provides precise flow to achieve excellent reproducibility of samples.
Repeated sample injection can achieve 0.0001-precision qualitative and quantitative repeatability index.
 *EXFORMMA ARCUS series of chromatographic columns are used under the specified laboratory conditions

Rt	3.792	3.790	3.791	3.788	3.790	3.792	RSD=0.04%
A	235616	235165	235479	235292	235190	235392	RSD=0.07%

●  Sensitivity

The flow cell with unique design of double parallel conical bores, in combination with imported high-performance deuterium lamp, enables the baseline to be more stable with the best sensitivity.

● Good Selectivity

EX1600 system provides not only the most commonly used UV detector, but also different detectors based on each sample’s characteristics, and provides the appropriate applied analysis conditions, e.g. Refractive Index Detector suitable for sugar and superpolymer analysis, Evaporative Light Scattering Detector for analysis of non-volatile organic compounds, and Fluorescence Detector for analysis of organic compounds with fluorescent substance or with derived fluorescent substance.

Established in 1998, Shanghai Wufeng Scientific Instruments Co., Ltd. (Wufeng Instruments) is a high-tech enterprise integrating development, design, production and sales. Through over 10 years of its efforts, Wufeng Instruments has become one of the key domestic manufacturers of HPLC, and its products include other chromatographic analyzers and related devices, software and accessories.

"Innovative, Leading and Considerate" reflects Wufeng's culture.

Innovative: Innovation is the cornerstone of our success. Over the past more than a decade, we have, with the spirit of innovation, independently developed outstanding analytical instruments, from the initial chromatographic data processor to the current liquid chromatograph as our main products. We hold 100% of intellectual property right in “Wufeng” brand products. We have stressed on fund and manpower input in development, and by making full use of the latest technology of micro-electronics and precision machinery processing, regarding international top products as benchmark, endeavored to overcome technological problems at home and abroad so as to produce the products reaching international advanced level and meeting needs of customers.

Leading ： We will never be content with status quo, and will continue to seek a breakthrough. And we have a strong desire of self-perfection to constantly win the market. At present, we have two major series of HPLC, i.e. LC-100 and EX1600 to meet the needs of customers. Our products have gradually gained the recognition from market in terms of quality, from the top-in-sale chromatographic data processor in domestic market 10 years ago to the ceaseless increase in the popularity and market share of HPLC at present time. In the following several years, we will continue to introduce new products and actively exploit the market and various industrial fields.

Considerate: We treat our customers in good faith, and develop and produce our products in a scrupulous manner. All our product promotions and technical exchanges are conducted based on rigorous scientific approach, never misleading customers. We also pay attention to the communication with customers, in order to constantly perfect our products according to their feedback.

Wufeng Instruments has focused on its every link in details. In terms of development, consistently taking world top instruments as our benchmark, we have made repeated test and demonstration hundreds of times; in production, we are the first domestic manufacturer to test and inspect components and whole instruments by using all-digital monitoring system; in terms of selling, we spare no efforts to provide our customers with better cost-performance products and excellent after-sale service, always paying attention to the perception of customers.
