Standard Practice for Analysis of Water-Formed Deposits by Wavelength-Dispersive X-Ray Fluorescence
5.1 Certain elements present in water-formed deposits are identified. Concentration levels of the elements are estimated.
5.2 Deposit analysis assists in providing proper water conditioning.
5.3 Deposits formed from or by water in all its phases may be further classified as scale, sludge, corrosion products, or biological deposits. The overall composition of a deposit or some part of a deposit may be determined by chemical or spectrographic analysis; the constituents actually present as chemical substances may be identified by microscope or X-ray diffraction studies. Organisms may be identified by microscopical or biological methods.
1.1 This practice covers X-ray spectrochemical analysis of water-formed deposits.
1.2 The practice is applicable to the determination of elements of atomic number 11 or higher that are present in significant quantity in the sample (usually above 0.1 %).
1.3 The values stated in SI units are to be regarded as standard.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
