For acid sensitive compounds subject to degradation on normal-phase silica

Neutral alumina columns are useful when samples are acid sensitive and prone to degradation on normal phase silica gel. Acid and basic alumina columns are useful when purification of a compound with those properties is considered. This avoids the solvent swapping and additional extraction, washing, and concentration involved in recovering target compounds from collected fractions containing a mobile phase modifier such as triethylamine or acetic acid.​

Standard Features

  • Column sizes available for purifying milligrams to several grams

  • RFID technology for automatic set up on compatible instruments
