AI Article Synopsis
- A new method for creating poly(styrene-divinylbenzene-methacrylic acid) monolithic columns for capillary liquid chromatography is presented.
- The study explored how varying methacrylic acid levels influence the columns' structure and performance.
- Results show that these columns provide high separation efficiency and consistent retention times for small organic molecules, with efficiency reaching about 28,000 theoretical plates/m and excellent repeatability.
Article Abstract
A very simple and readily performed method is described for the preparation of poly(styrene-divinylbenzene-methacrylic acid) monolithic columns for capillary liquid chromatography. The effect of the methacrylic acid content on the morphological and chromatographic properties has been investigated. Methacrylic acid is shown to be essential for isocratic separations of small organic analytes by capillary liquid chromatography. Column efficiencies of about 28,000 theoretical plates/m have been obtained for all the test compounds. The batch-to-batch and run-to-run repeatability of the retention times is better than 1.5%.
