A 5-cm-long polymer-based chromatographic monolith was fabricated and used as the stationary phase for high-performance liquid chromatography to quantitatively determine six aroma compounds in edible spices, namely, anethole from star anise, trans-cinnamaldehyde from cinnamon, hydroxy-alpha-sanshool from zanthoxylum, as well as 6-gingerol, 8-gingerol, and 10-gingerol from ginger.
A polymer-based chromatographic monolithic column was prepared via in-situ radical polymerization using tetrahydrofurfuryl methacrylate as the monomer.
A phenyl-based polymer monolithic column was prepared via free radical polymerization in a stainless steel column with the size of 4.6 mm i.d. × 50 mm, using ethylene glycol phenyl ether acrylate as the monomer. The resulting monolithic column shows high porosity of 73.42% and relative uniform pore structure, as characterized by mercury porosimetry and scanning electron microscopy, respectively.
A cycloalkyl-based polymer monolithic column for solid-phase extraction was prepared via radical polymerization using cyclohexyl methacrylate as the monomer.

成都麦德生科技有限公司于2018年首次从四川花椒中提取分离，由于山椒素类单体的不稳定性经过几次产品工艺的改进，现在能稳定的提供纯度达到98%（HPLC-DAD）以上高纯度单体。公司立足于花椒项目的研发，花椒品种的筛选，经过3年时间从花椒（青...
受某中医药大学老师的委托，分离老师提供的药材乙酸乙酯部位的化合物，化合物含量极低。通过多种分离纯化手段，在2个月时间内（近期圆满收尾结束），总共分离出26个化合物，大部分纯度在98%以上。公司的纯化分离技术和专业受到老师肯定和赞扬。
