摘要
研究了6种代表元素在美国P-E公司横向加热石墨管(THGA 管)与国家地质实验测试中心研制的横向加热石墨管中的原子吸收曲线轮廓,考察了6种元素在两种石墨管中的灵敏度、精密度、准确度。实验表明用国产横向加热石墨管替代PE公司THGA石墨管是完全可行的。
The outline of atomic absorption curves for 6 elements of two kinds of graphite tube heated horizontally, made by Perkin Elmar Company (USA) (THGA Tube) and by China National Examination and Testing Center for Geology (CNETCG Tube) respectively, was studied.The sensitivity, precision and accuracy for 6 elements with these two kinds of graphite tube was investigated.The results demonstrated that using home-made graphite tube (CNETCG Tube) instead of the PE-made tube (THGA Tube) was completely feasible.
