原理 静脉血的铅、镉经0.8N硝酸处理后,红细胞被破坏,离心去除细胞碎片,即得含铅、镉上清液;随后,即将该上清液导入石墨炉原子化器原子化,并根据其特征谱线的吸收强度定量。 仪器
Principle Venous lead, cadmium by 0.8N nitric acid treatment, the destruction of red blood cells, cell debris by centrifugation to remove lead, cadmium supernatant was obtained; then, the supernatant will be introduced into graphite furnace atomizer atomization and According to its characteristic absorption intensity spectrum quantitative. instrument
