• Strongest anion exchange sorbent because of its quaternary amine
fundimal group
• Positive charged, better retention of weaker anions such as carboxylic
acids that may n ot retain strongly enough en PSA or NH 2
• Activate the im exchanger
by
conditioning it with appropriate bufers
• Strongest cation exchange sorbent because of its benzenesulfonic
acid functimal group
• Optimized fa- use in organic applicati cns
• Nonpolar character exhibited by benzen e ring is useful to
corrp ounds with both cationic and nonpolar properties in aqueous
solvent

• The most polar sa-bent, m e of the best sa-bents available fa–
selectively separatin g analytes of very similar structure
• Extract various corrp omds frem non-polar solvents using hydrogen
bonding, accorrplishing the elution successively with increasing the
solvent polarity
• Excellent capacity for removing target molecules frem rea ction
by-produ cts and excess reagents
• Fkrisil is a magnesia silica gel, a polar sa-bent capable to extract
polar compounds from nonpolar matrix
• Separate chlorinated pesticides, amines, herbicides, PCBs, ketones,
organic acids and phenols
• Alumina-A enhances Lewis acid prcperties, wh ich makes the sa-bent
ma-e retentive towards electron-rich compounds
• Alumina-A has a slightly cationic nature through pretreatment with
acidic solutions
• Suitable for retention neutral and
anicnic
