This paper describes two methods of 4th derivative spectrophotometryfor the determination of carboxyhemoglobin in blood.Both of them areaccurate,precise and reliable.The first of them requires preparation ofblood solution saturated with carbon monoxide from the blood to be ana-lysed.But its accuracy is effected by the stability of the spectrophotome-ter used slightly.The second method is simpler and more rapid one.But its accuracy may be notably effected by the stability of the spectrophotome-ter used.

本文报导了两种利用四阶导数光谱测定血液 HbCO%的方法。一种需从检血制备一氧化碳饱和血溶液,操作稍繁但准确可靠,受仪器稳定性影响较小。另一种不需制备一氧化碳饱和血溶液,是一种操作简单,快速亦准确可靠的方法,但由于计算中使用预先测定的常数,测定的准确性乃受仪器稳定性波动的影响。
