Additional information

1. Scope

1.1 These test methods cover the photometric and atomic absorption determination of arsenic in most waters and wastewaters. Three test methods are given as follows:

Concentration Sections Range Test Method A-Silver Diethyldithio- 5 to 250 [mu]g/L 7 to 15 carbamate Colorimetric Test Method B-Atomic Absorption, 1 to 20 [mu]g/L 16 to 24 Hydride Generation Test Method C-Atomic Absorption, 5 to 100 [mu]g/L 25 to 33 Graphite Furnace

1.2 The analyst should direct attention to the precision and bias statements for each test method. It is the user's responsibility to ensure the validity of these test methods for waters of untested matrices.

1.3 This standard does not purport to address all of the safety problems, 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. For specific hazard statements, see Notes 1 and 5.
