Electrodeionization devices typically comprise semi-permeable ion-exchange membranes and permanently charged ion-exchange media see Test Method D RO removes ions based on electrochemical forces, colloids, and organics down to molecular weight. May also be called hyper? Also, different types of contaminants affect these methods and processes differently.

It is intended to satisfy the requirements for normal laboratory procedures, but does not necessarily apply to the large-scale production of pure water or for speci? Different grades of water may be covered by other ASTM speci? Use and Application 5. It should be noted also that the method may or may not remove non-ionized dissolved gases. The instructions of the manufacturer of the resins or the resin cartridge bed should be followed.

However, the method of storage and handling of the water may itself result in contamination. Sample containers and tubing should be made of? Practice D should be consulted.

This procedure is most easily carried out by autoclaving at kPa 15 psi for 20 min. The use of reagent grade water should recognize that analytes may exist in water that meets the criteria listed in Section 1, but these analytes may interfere with the use of the water. These issues are very complex and extensive. This guidance is not intended to be comprehensive d1193-9 complete. Producers and users of Reagent Water are encouraged to seek out v1193-91 sources of guidance in this area.

The impact will be different depending on the water type and grade produced resistivity characteristics for example, will be rapidly impacted as soon as Type I water is be stored. Water types, other than Type I, can be stored if particular attention is taken regarding the materials, design of the storage system and time of storage.

The material of the storage reservoir in contact atm water should be selected to minimize the release of extractables. This should be achieved by air? It should be recognized that the mere fact that the water is stored will likely reduce its purity despite attempts to prevent contamination. Storage should be sized to ensure a good turnover of water.
