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.

成都麥德生科技有限公司于2018年首次從四川花椒中提取分離，由于山椒素類單體的不穩定性經過幾次產品工藝的改進，現在能穩定的提供純度達到98%（HPLC-DAD）以上高純度單體。公司立足于花椒項目的研發，花椒品種的篩選，經過3年時間從花椒（青...
受某中醫藥大學老師的委托，分離老師提供的藥材乙酸乙酯部位的化合物，化合物含量極低。通過多種分離純化手段，在2個月時間內（近期圓滿收尾結束），總共分離出26個化合物，大部分純度在98%以上。公司的純化分離技術和專業受到老師肯定和贊揚。
