CNAS CERTIFIED LAB

Hangsen Research Institute‘s CNAS-certified laboratory was established in 2016, making it one of the first laboratories in the vaping industry to receive CNAS certification. Currently, the laboratory is equipped with cutting-edge analytical testing equipment, providing comprehensive compliance testing and analysis services. We believe that the use of advanced equipment and scientific analytical methods, combined with the separation, identification, and quantification of complex compounds, can effectively address various challenges encountered in the field of vaping.
