The principle of Lambert Beer's law
quantitative analysis
The rapid analysis of tea safety is based on the characteristic absorption spectrum and light absorption law of visible light produced by substance molecules (Lambert)The principle of Bill's Law is an instrument used for quantitative analysis by comparing an unknown concentration sample with a known concentration standard substance.
