We know that the quality of products is the basis for the survival and development of the company. Our quality policy is to "exceed customer expectations".

Our research and production process are guided by the concept of "design quality". First, we eliminate the route that produces more relevant impurities, and then select key production parameters through a large number of experiments, including raw material quality, intermediate quality control, equipment type and so on. With this standard quality system, we will be your strategic manufacturing partner, providing you with reliable, cost-effective intermediate products, ranging from a few grams to metric tons. We take a holistic approach to business lifecycle management. Through the continuous improvement program, we regularly review our manufacturing processes and perform performance trend analysis to ensure long-term cargo cost reduction and second-generation process innovation where possible.

In addition, we continuously improve every link of quality control and improve product quality by strengthening staff training, improving testing technology and perfecting testing indicators.Implement the latest requirements and indicators of Chinese pharmacopoeia as well as European and American pharmacopoeia, strictly control the quality attributes of each key product, and ensure consistency and reliability in the process of customer's use.

We adopted analysis methods not limited to the following:

•Chromatography (HIGH performance liquid chromatography; Thin layer chromatography; Gas chromatography)
•Mass spectrometry (liquid-mass combination)
•Spectroscopy (INFRARED, ULTRAVIOLET), atomic absorption, nuclear magnetism
•Determination of physical constants
•Optical rotation measurement
•Content analysis
•Elemental analysis
•Titration (acid titration; Basic titration; Coordination titration; Non-aqueous titration; REDOX titration)
•Mixed with water test
•Determination of evaporation or burning residue
•Nonvolatile determination
•Clarity test
•Dry weightlessness, Carl Fisher determination
