Chemical analysis lab

TIME: 2015-05-29  SOURCE: 【PRINT】

Research direction and realm:

The Lab is specialized in analyzing atmosphere, aerosol, dust, earth samples and other novel chemical analytical activities. It dedicates in fast and comprehensive detection of regular chemical compounds, and non-regular analysis of chemical compounds. Also the lab is conducting new analytical method research and development. Currently, the instruments employed in this lab include ICP-AES which is able to detect more than 30 different elements with a high resolution and accuracy. Based on EPA TO-11A method, we designed a new methodology by combining the traditional DNPH method with HPLC-UV to separate the VOCs in atmosphere. This method can detect 22 different chemical compositions of carbonyl compounds and has been applied in the chemical analysis for samples taken in over 10 cities in China. Moreover, lab will launch a project to explore a novel method to combine the VOCs sorbent tube and GC-MSD/FID/ECD to detect the BVOCs therefore to realize detecting the BVOCs in atmosphere.

 

Lab’s service:

1 aerosol, dust and earth sample analysis

2 sampling and quantifying the carbonyl compounds and particles in atmosphere
