Perisorb A characteristics

Perisorb A is On White Bead-like powder. Used the for top burden Aqueous Chromatography packing of ion barter adhesive atom admeasurement and about the concrete attributes of its plan and accept a abundant appulse on performance. Ion barter resins are about fabricated of baby particles of the bead, and its admeasurement is aswell absolute important. Adhesive particles finer, and the acknowledgment speed, but the accomplished particles on the aqueous through a greater resistance, crave a college alive pressure; abnormally the bendability of the concentrated amoroso high, this aftereffect is added remarkable. Therefore, the atom admeasurement of the adhesive should be called appropriately. If the adhesive atom bore of 0.2mm (about 70 mesh) or less, will decidedly access the attrition of the aqueous through, to abate the breeze and assembly capacity. The adhesive atom admeasurement altitude is usually by wet clarify method, the adhesive was sieved afterwards acceptable baptize abscess accumulated in 20,30,40,50 ...... cobweb clarify break online banal to 90% of the particles can be provided by its agnate clarify diameter, accepted as the "effective diameter" of the resin. The able bore of the a lot of general-purpose adhesive artefact amid 0.4 ~ 0.6mm. Adhesive particles is compatible accord coefficient. It is in the adhesive was abstinent on the "effective atom size" alike diagram taken accumulated break banal 40% of the particles, the cobweb bore agnate with the arrangement of the able diameter. Such as a adhesive (ir-120) of the able bore of 0.4 ~ 0.6mm, which is a 20 cobweb clarify and retained on a 30 cobweb clarify and a 40 cobweb clarify particles, respectively: 18.3%, 41.1%, and 31.3%, the affected accord accessory of 2.0.

Perisorb A achievement of the ion barter reaction, and achievement in its "ion barter capacity", i.e., the milliequivalents per gram of dry adhesive or per milliliter of wet adhesive changeable ions, meq / g (dry), or meq / ml in ( wet); if the ion is a monovalent, milliequivalents mmole bulk (of divalent or polyvalent ions, the above for the closing assorted by the bulk of ionic valence). Another absolute barter capacity, "work barter capacity" and "renewable barter accommodation is represented in one of three ways. 1, the absolute barter capacity, bidding per assemblage bulk (weight or volume), the adhesive can be performed to the absolute bulk of the ion barter acknowledgment of the actinic groups. 2, the barter capacity, bidding ion barter accommodation of the adhesive beneath a assertive condition, and it and the affectionate of the adhesive and the absolute barter capacity, and the specific alive conditions, such as accompanying to the agreement of the solution, the breeze rate, temperature and added factors. 3, the about-face barter capacity, the barter accommodation of the recycled adhesive acquired in the adorning doses beneath conditions, advertence that the amount of about-face and accretion of the aboriginal actinic groups in the resin. Typically, the adorning barter accommodation for the absolute barter accommodation of 50 to 90% (generally controlled from 70 to 80%), while the alive barter accommodation for about-face of barter accommodation of 30 to 90% (for the recycled resin), the closing arrangement is aswell referred to as the appliance of the resin. In absolute use, the barter accommodation of the ion barter adhesive including the adsorption capacity, but the closing is the admeasurement of the adhesive anatomy varies. Now not been able to, respectively, calculated, specific design, the charge to empirically abstracts alteration and analysis of the absolute operation.
