在 WYX—402型原子吸收分光光度计上用火焰法测血浆(特别是红血球)中的微量元素时,经常发生随着分析样品的增多,燃烧头狭缝就会被干燥了的样品堵塞。我们在测红血球中的 Cu 时,红血球用去离子水1∶10稀释后测定,发现每测十个左右样品时,燃烧头狭缝就 When trace elements in blood plasma (especially red blood cells) are flame-measured on the WYX-402 atomic absorption spectrophotometer, it often happens that as the sample is analyzed, the burner head slit is clogged with the dried sample. When we measure Cu in red blood cells, erythrocytes are measured 1:10 after diluted with deionized water and found that for every ten samples tested,
