Experimental Detection

Zhejiang Gold Kropn Biotechnology Co.,Ltd Product Testing Laboratory
  

Zhejiang Gold Kropn Biotechnology Co., Ltd product testing laboratory equipped with professional testing equipment, including liquid chromatograph, gas chromatograph, UV-visible spectrophotometer, gel chromatography, infrared spectroscopy, atomic absorption spectrophotometer and other large-scale precision equipment. Gold Kropn laboratory has established close cooperation with Zhejiang University Testing Center and Pharmaceutical Engineering Institute, conduct research on the quality standards and control process of modified pectin together.

In addition to conventional indicators of physical and chemical detection, Gold Kropn established new testing methods, such as using gel chromatography to analysis molecular weight of modified pectin, and using gas chromatography to test the esterification degree, thus to provide strong guarantee on the quality of modified pectin. Gold Kropn hired professor Li Yinghua as the technical adviser of analysis and testing center, she makes many advice and guidance on the technical problems.
