摘要
本文研究了全血和血清背景吸收的来源及特点。未经处理血清背景吸收的波长特性与灰化温度有关,经过干灰化处理全血背景吸收的波长特性与氯化钠相似,表明其背景主要来自氯化钠。全血和血清的背景吸收输廓与原子化阶段的加热方式和原子化温度有关。
The character and source of background absorption of whole blood and serum are studied. The wavelength-dependence of the background of whole blood treated with ashing is quite similar to that obtained from sodium chloride. This shows that non-specific absorption of whole blood arises mainly from sodium chloride. The background absorption VS atomization time is dependent on the atomization temperature and heating rate.
