ASTRA Diol
ASTRA® HPLC columns extend our ARION® and CHROMSHELL® product lines. The ASTRA® has been developed in the Czech Republic to offer an alternate to a broad range of general HPLC columns. ASTRA® brings completely new and unique stationary phase with the polar embedded group to offer a complementary selectivity (ASTRA® DM). Aplications on Astra® HPLC columns are available at APPLICATION LIST
