Restek™ Allure® HPLC Columns are based on high purity spherical type B silica with a particle size of 5 µm and a pore size of 60 Å.
Due to the different modifications, Restek™ Allure® phases are suitable for various applications. Allure® AK and Allure® Organic Acids are application-specific HPLC columns, Allure® AK for the analysis of DNPH-derivatized aldehydes and ketones and Allure® Organic Acids for the analysis of organic acids.
