1.1This guide describes quality assurance (QA) protocols for the determination of the anions and cations in Atmospheric Wet Deposition (AWD) shown in Table 1.

TABLE 1 Common Techniques of Analysis for Atmospheric Wet Deposition Samples

Automated Colorimetry	Ion Chromatography
NH₄⁺	Cl^–, NO₃^–, SO₄^2–, NH₄⁺, Ca²⁺, Mg²⁺, Na⁺, K⁺
Flame Atomic Absorption Spectrophotometry	Electrometric
Na⁺, K⁺, Ca²⁺, Mg²⁺	pH, specific conductance
Inductively Coupled Plasma Spectrometry
Na⁺, K⁺, Ca²⁺, Mg²⁺

1.2Included in this guide are minimum recommended requirements for the preparation of calibration standards and suggested procedures for validating laboratory measurement results.

1.3This guide describes minimum requirements for the frequency of analysis of quality assurance samples and recommends procedures for the evaluation of quality assurance data.

1.4The guide's recommendations are based upon expected anion and cation concentrations in AWD (1) ² and Appendix X1.

1.5The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.6This 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.
