ASTM E3203-2019 用电感耦合等离子体发射光谱法测定干漆、土壤和擦拭试样中铅含量的方法 Standard Test Method for Determination of Lead in Dried Paint, Soil, and Wipe Samples by Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES)

1.1 This test method specifies a procedure for analysis of dried paint, soil, and dust wipe samples collected in and around buildings and related structures for lead content using inductively coupled plasma-optical emission spectroscopy (ICP-OES).

1.2 This test method should be used by analysts experienced in the use of ICP-OES, the interpretation of spectral and matrix interferences, and procedures for their correction. For determination of lead (Pb) and other metals in air by ICP-OES, see Test Method D7035.

1.3 This test method cites specific methods for preparing test solutions of dried paint, soil, and wipe samples for analysis.

1.4 It is the user’s responsibility to ensure the validity of this test method for sampling materials of untested matrices.

1.5 No detailed operating instructions are provided because of differences among various makes and models of suitable ICP-OES instruments. Instead, the analyst shall follow the instructions provided by the manufacturer of the particular instrument. This test method does not address comparative accuracy of different devices or the precision between instruments of the same make and model.

1.6 This test method contains notes that are explanatory and are not part of the mandatory requirements of this test method.
