| Titanium | 0.0001–6.0 |
| Tungsten | 0.01–5.0 |
| Vanadium | 0.0005–1.0 |
1.2 The following elements may be determined using this method.
| Element | Quantification Range (μg/g) |
|---|---|
| Antimony | 0.5–50 |
| Bismuth | 0.1–11 |
| Gallium | 2.9–54 |
| Lead | 0.4–21 |
| Silver | 1–35 |
| Tin | 2.2–97 |
| Thallium | 0.5–3.0 |
1.3 This method has only been interlaboratory tested for the elements and ranges specified. It may be possible to extend this method to other elements or different composition ranges provided that method validation that includes evaluation of method sensitivity, precision, and bias as described in this document is performed. Additionally, the validation study must evaluate the acceptability of sample preparation methodology using reference materials and/or spike recoveries. The user is cautioned to carefully evaluate the validation data as to the intended purpose of the analytical results.
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 safety hazard statements are given in Section 9.
