oxygen produced from
the hydrogen peroxide then reacts with the luminol dianion. The product of this reaction is very
unstable and immediately decomposes with the loss of nitrogen to produce 5-aminophthalic acid
with electrons in an excited state. As the excited state relaxes to the ground state, the excess
energy is emitted as blue light.
4. The detecting of hemoglob
In catalyst, oxygen produced from H202
With sodium hydroxide, luminol Dianion is formed
The oxygen reacts with luminol dianion
This product is very unstable, so decomposes to 5-aminophathalic acid
As the exited state, 5-aminophathalic acid relaxes to ground state
Excess energy is emitted as blue light
Alkaline luminol, H2O2 solution is used on detecting NO2
The presence o
need a catalyst to accelerate the process. The catalyst in this case is the iron in hemoglobin . If hemoglobin and the luminol mixture come in contact, the iron in the hemoglobin accelerates a reaction between the hydrogen peroxide and the luminol. In this oxidation reaction, the luminol loses nitrogen and hydrogen atoms and gains oxygen atoms, resulting in a compound called 3-aminophthalate.

Pulse Oximeter(PO)는 혈액내의 산소포화도를 측정하는 것으로써 이는 총 헤모글로빈의 농도에 대해 산소를 포함하고 있는 헤모글로빈 농도의 비율로서 정의되어지는데, 이러한 비관혈적인 방법은 혈액의 채취나 카테터의 삽입 없이 혈액내의 산소 포화도를 측정함으로써 환자에게 고통을 주지
