[Preparation and evaluation of a strong polar polymer capillary column].
A strong polar organic polymer porous layer open tubular capillary column, named OPPLOT-A column, was prepared by in situ copolymerization with the strong polar acrylonitrile as monomer and divinylbenzene as cross-linking agent. The polarity of the column is higher than that of the OPPLOT-Q, OPPLOT-R andd OPPLOT-S columns which prepared previously. The performance of the OPPLOT-A column was evaluated. It is effective to analyze alcohols, aldehydes, ketones, esters, ethers and nitriles etc., and especially for good separation of nitriles and aldehydes. The retention of the column is not influenced by water. The thermal stability of the OPPLOT-A column (200 degrees C) is lower than that of OPPLOT-Q (250 degrees C), -R (250 degrees C) and-S (210 degrees C).
