| Abstract: | Summary An improved system is reported for the determination of tin in copper-based alloys by flame-atomic absorption specved sensitivity and precision by factors of 2–3 compared to that obtained using conventional flame AAS. Determination of tin in a series of certified references samples demonstrates the improved precision of the proposed procedure. |
