Dears,

At higher concentrations, Beer Lambert law deviates from linearity.
What is that highest concentration? Is this vary experiment to experiment?

I am asking this question because i am in dilemma that what should be the highest conc. of the
standard while calibrating equipments based on this law.

Kind Regards,

Dear dastgir;

It is not the Beer-Lambert Law that not holds at high concentration, it is the experimental conditions which no longer hold for the Law!

Yes!,  - it is different from substance to substance and from experimental condition to experimental condition.

The individual upper conc. limit you have to determine during the calibration!

Good Luck!

Dear ARGOS++,

Which conditions are you talking about?

Kind Regards,

Dear dastgir;

It are the same conditions as are valid for the ε (Epsilon) on:

"Corrected Beer's Law"

It’s because the ε depends on them (the experimental environment).

But most important are the solvent or solvent-mixture, and pH, and of course the concentration itself ( because  = μ_r)!

Good Luck!
