两种横向加热石墨管原子化性能的比较

Comparison of Atomization Characters for Two Type of Transverse Heated Graphite Tube

研究了 6种代表元素在PE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测定的灵敏度、精密度、准确度。实验表明 。

The atomization behaviors for six typical elements in transverse heated graphite tubes produced by Perkin Elmer Co. and by National Research Center of Geoanalysis (China) have been studied. Sensitivity, precision and accuracy for six elements in two types of graphite tubes were compared.Experiment results show that atomization performances for these two types of transverse heated graphite tubes are comparable and the home made products can replace the P E products in use.
