Chapter 1 Introduction
1.1 Test principle
The Bio-chemical analyzer is mainly used for the quantitative analysis of the clinical bio-chemical
items, it applies to the Lamber- Beer law:
A=Kbc=lg(I
0
/I)
Among them:
A: Absorbance
K: Absorbent Index
B: Liquid layer’s Thickness
C: Solution’s Consistency
I
0
: Incident light’s Strength
I: Transmit light’s Strength
According to the above formulas, under the condition of the certain liquid layer’s thickness and
incident light’s strength, as long as test the strength of transmit light which goes through the liquid
layer , so we can calculate the consistency of the given solution.
