This product is a strongly acidic cation exchange resin in the H+ form. There is no way to convert between this and being in the chloride form, which would constitute an anion exchange resin. A resin cannot be converted from an anion exchange resin to a cation exchange resin, or vice versa. A resin in the H+ form can, however, be converted to the sodium form by flushing with two volumes of 1 N NaOH, whereby the sodium ions take the place of the hydrogen.

What is the meaning of 1.7 meq/mL by wetted bed volume for this resin? Do we have to consider the molecular mass of resin or the reaction mixture that we are going to purify?
1 answer-
A milliequivalent is one-thousandth of an equivalent. The unit mEq is related to the number (mmol) and electrical charge of ions in solution. 1.7 mEq/mL means 1.7 millimoles of charge per milliliter of resin bed.
Yes, you will need to consider the milliequivalents of charge on the resin and the millimoles of the material that you are trying to purify; make sure that the first is greater.

What is the particle size of Product 217506, Dowex® 50WX8 - hydrogen form, 100-200 mesh resin?
1 answer-
This is Dowex 50Wx8 100-200 mesh, with beads measuring 75-150 microns. This particle size is consistent in water, but the resin will shrink when exchanged to other cationic forms, and it will swell when exposed to organic solvents. You may test the swelling characteristics of a resin to be used in your application by doing the initial solvent exchanges in a graduated cylinder.

How do I prepare Product 217506, Dowex® 50WX8 - hydrogen form, 100-200 mesh resin, for use?
1 answer-
Cation exchange resins can be prepared by initially swirling with deionized water in a flask (no stir bars, please), allowing them to settle for 15-20 minutes, and decanting the fines. To fully activate the resin, repeat the procedure 2-3 times with 2N hydrochloric or sulfuric acid, and rinse with copious amounts of water until >pH 5; this procedure may be completed with use of a Büchner funnel.

Is Product 217506, Dowex® 50WX8 - hydrogen form, 100-200 mesh resin, the same as AG50W-X8?
1 answer-
The AG® designation indicates that a resin has been specially cleaned and certified for analytical use. In most cases, resin that you prepare yourself will be suitable for your application. (® Bio-Rad Laboratories, Hercules,CA)
