Principle
When a monochromatic light through the test solution, the light will be absorbed. Light be absorbed proportional to the concentration of the test solution. Conform Beer’s law:
A= log(1/T)=log(I0/I)
T Transmission
I0 Incident light intensity
I Transmitted light intensity
A Absorbance
Oil concentration:
C=X×A2930+Y×A2960+Z×(A3030-A2930/F)
C Oil concentration
A2930,A2960,A3030 Absorbance under different wavelengths
X,Y,Z,F Correction factor
