Descrizione generale
The DE weak (charge dependent on pH) anion exchangers are based on the diethylaminoethyl (DEAE) tertiary amine functional group. QA52 is a strong (charge independent of pH) anion exchange medium, containing quaternary amine groups.
DE23 dry fibrous DEAE cellulose - Allows fast flow rates especially after fines removal; suitable for negatively charged biopolymers.
DE32 dry microgranular DEAE cellulose - Similar performance characteristics after precycling as DE52.
DE52 preswollen microgranular DEAE cellulose - Probably the most widely used DEAE cellulose in the world; used for biopolymers with low to high negative charges; exhibits excellent resolution with good flow rates.
DE53 preswollen microgranular DEAE cellulose - Partially quaternized DEAE anion exchanger, highly substituted and with higher capacity than DE52; can be used in series with DE52 media.
QA52 preswollen microgranular QA cellulose - A strongly basic, quaternary amine-bearing anion exchange medium, moderately substituted, with high protein capacity. Fully ionized, bears constant charge under all pH conditions; excellent for high pH applications.
