A single modular, versatile, effortless and sensitive IonQuest ion chromatography system

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 tri…
