Coating is the core of SBSE technique, which determines the selectivity and extraction capacity of analysis. In this review, a brief introduction of extraction principle, extraction/desorption mode and their influencing factors of the stir bar sorptive coatings are made, and then the preparation techniques and methods of SBSE coatings are focused on. Finally, the advantages and disadvantages of SBSE coatings are discussed and overview of future development trends of SBSE coatins is given. 查看全文查看/发表评论下载PDF阅读器 相关附件:版权转让声明书 -->
