This document introduces a technique for analyzing zinc-based alloys using atomic absorption spectrophotometry. The technique can be used to measure zinc, aluminum, copper, iron, lead, and tin.
This document outlines a method employed by Agilent Technologies for the routine determination of major and minor constituents in non-ferrous metal alloys, specifically a zinc-based alloy. The technique utilizes atomic absorption spectrophotometry to analyze zinc, aluminium, copper, iron, lead, and tin.
| Zinc concentration range | 2,000-10,000 ppm |
|---|---|
| Aluminium concentration range | 20-150 ppm Al |
| Copper concentration range (low sensitivity) | 5-20 ppm Cu |
| Iron concentration range | 2-10 ppm Fe |
| Lead concentration range | 1-20 ppm Pb |
| Tin concentration range | 5-30 ppm Sn |
The method is used to analyze zinc, aluminium, copper, iron, lead, and tin.
An air-C,H, flame is recommended using the resonance line at 3075.9 A.
A N,0-C,H, flame is used with the 3092.7 A, 3092.8 A doublet.
Larger weights of sample, such as 2-3 g alloy per 100 mL, are recommended to improve accuracy.
