044078 描述保護(hù)柱 IonPac AG11 Guard Column 4 x 50 mm

The AS11 is a relatively low-capacity column designed for fast,gradient screening of inorganic anions and organic acid anions in simple sample matrices. ? Fast analysis of organic acids and inorganic anions in wellcharacterized samples ? Ideal for highly charged anions, including polyphosphates and polycarboxylates ? For organic acids and inorganic anions in complex sample matrices ? Low capacity translates into fast analysis times and high throughput The AS11 is designed for fast profiling of inorganic anions and organic acid anions in foods, beverages, chemical process solutions, wastewater, brines, and power plant waters. The AS11 column can resolve a large number of inorganic anions and organic acids in approximately 15 minutes.
