GSO OIML R100-1:2016 Scope
1.1 This Recommendation provides requirements for defining, testing and verifying the
performance of atomic absorption spectrometer (AAS) systems when used for measuring
metal pollutants in water as mandated by national laws and regulations. It does not intend to
exclude any other equivalent means of measuring metal pollutants in water. An AAS system
can be applied simply and rapidly for the determination of a variety of metals in potable,
ground, surface and saline waters as well as domestic and industrial wastewaters. An AAS
system of this type may be applied for the determination of metal concentrations in other
matrices such as soil, etc. References [1] – [4] give a description of the AAS system and some
applications.
1.2 The flame and electrothermal atomization (furnace) types of AAS atomizers are covered by
this Recommendation. The hydride generation and the cold vapor techniques are also briefly
described. The conditions of operation described for each system type are intended to cover
applications for trace analysis.
1.3 It is possible that the performance of an instrument can exceed the minimum criteria
prescribed in this Recommendation for these applications. Higher accuracy and repeatability
of measurements can be accomplished by careful attention to the optimization of the
performance of each of the instrument’s components. In such cases, success may also depend
on the knowledge, skill, and experience of the analyst, as well as the quality of instrument
manufacture.
1.4 A sample usually needs to undergo a specific preparation technique prior to analysis with an
AAS system. Sampling techniques, methods of analysis and impact of interfering components
are beyond the scope of this Recommendation. As appropriate, the relevant international,
regional or national sampling techniques and reference methods of analysis should be applied.
1.5 This Recommendation does not address requirements and tests that may be necessary for
operator safety. Therefore, users should determine whether an instrument meets the safety and
labeling requirements specified in national regulations.
