 Refiner INDUSTRY |
Purified water is commonly used in many industries and scientific organizations, for analytical purposes or in production processes. Therefore in order to encourage a better use, some international organizations have established quality standards for each type of application into:
- ISO (the International Organisation for Standardisation )
- ASTM (the American Society for Testing and Materials)
- NCCLS (the National Committee for Clinical Laboratory Sandards)
- the Farmacopoeia
These quality standards have led to the definition of three degrees of purity:
GRADE 1
Water essentially used for the dissolution of ionic and organic pollutants colloids. It is also used in high-precision analysis, in particular in HPLC chromatography. This type of water can be obtained starting from a GRADE 2 or through a further treatment with ion exchange resins, as well as a filtration on a porous septum to 0.2 microns for the elimination of organic residues possibly present, or for re-distillation.
GRADE 2
Water characterized by a really very low concentration of both organic and ionic contaminants that colloidal, is typically used for precision analysis, including atomic absorption spectrometry and in the determination of trace elements. This type of water can be obtained for multiple distillation or by treatment with reverse osmosis followed by ion exchange resins
GRADE 3
indicated water for general purposes of the chemical laboratory and in solution of the reagents preparations. This type of water can be obtained by distillation, ion exchange or reverse osmosis.
