摘要：

An improved system is reported for the determination of tin in copper-based alloys by flame-atomic absorption spectrophotometry. Use of a slotted-tube quartz atom-trap improved 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.
