Область применения

1.1 This test method is applicable to the determination of chloride, nitrate, and sulfate in atmospheric wet deposition (rain, snow, sleet, and hail) by chemically suppressed ion chromatography (1) using a two pen variable setting recorder and integrator. For additional applications refer to Test Method D4327.

1.2 The concentration ranges for this test method are listed below. The range tested was confirmed using the interlaboratory collaborative test (see Table 1 for statistical summary of the collaborative test).

Range of Range Method Tested MDL (mg/L)(2) (mg/L) (mg/L) Chloride 0.03 0.09-2.0 0.15-1.36 Nitrate 0.03 0.09-5.0 0.15-4.92 Sulfate 0.03 0.09-8.0 0.15-6.52

1.3 The method detection limit (MDL) is based on single operator precision (2) and may be higher or lower for other operators and laboratories. The precision and bias data presented are insufficient to justify use at this low level, however, many workers have found that this test method is reliable at lower levels than those that were tested.

1.4 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. Specific precautionary statements are given in Section 9.
