Inorganic Chemical Base
• Strongest anion exchange sorbent because of its quaternary amme
functimal group
• Positive charged, better retention of weaker anions such as carboxylic
acids that may net

bufers
• Strongest cation exchange sorbent because of its benzenesulfonic
acid functimal group
• Optimized fer use m «game applicati cns
• Nonpolar character exhibited by benzene

• The most polar scrbent, me of the best so-bents available fcc
selectively sep arating analytes of very similar structure
• Extract vanous corrp omds frem non-polar solvents usng hydrogen
bonding, accorrplishing the elution successively with mcreasmg the
solvent polarity
• Excellent capacity forremovmg target molecules frem reaction
by-products and excess reagents
• F krisil IS
a magnesia silica gel, a polar so-bent capable to extract
polar compounds from nonpolar matrix
• Separate chlorinated pesticides, arrunes, herbicides, PCBs, ketones,
ccgamc acids
and phenols
• Alumina-A enhances
LewIS
acid prcperties,
which
makes the
so-bent
more retentive towards electron-nch comp cunds
• Alumma-Ahas a slightly cationic nature through pretreatment with
acidic solutims
• Suitable for retention neutral and amcmc species
