Standard Test Method for Elements in Water by Inductively Coupled Plasma - Mass Spectrometry
1.1 This test method covers the determination of dissolved elements in ground water, surface water, and drinking water. It may also be used for the determination of total-recoverable elements in these waters as well as wastewater.2
1.2 This test method should be used by analysts experienced in the use of inductively coupled plasma—mass spectrometry (ICP-MS), the interpretation of spectral and matrix interferences and procedures for their correction.
1.3 It is the user's responsibility to ensure the validity of the test method for waters of untested matrices.
1.4 Table 1 lists elements for which the test method applies, with recommended masses and typical estimated instrumental detection limits using conventional pneumatic nebulization. Actual working detection limits are sample dependent and, as the sample matrix varies, these detection limits may also vary. In time, other elements may be added as more information becomes available and as required.
1.4.1 This method covers the analysis of mine dewatering groundwater and wastewater effluent in the range of 2–120 μg/L dissolved antimony and 3–200 μg/L dissolved arsenic.
1.4.2 This method covers the analysis of metallurgical processing cyanide solutions in the range of 1–500 µg/L dissolved gold.
1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.6 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.
