CNAS CERTIFIED LAB
In order to meet the needs of fast and accurate quality testing, Hangsen established the industry's first CNAS certification laboratory in 2016. The laboratory is equipped with the most advanced physical and chemical testing equipment in the industry, such as liquid chromatograph and gas chromatograph, which can meet the high standard testing requirements of the pharmaceutical industry. Accurate detection of dozens of harmful substances such as pollutants, carbonyl compounds, heavy metals, microorganisms, nitrosamines, etc..
