Discussion
How is quantitative infrared analysis usually carried out?
Answer: A
A sealed liquid cell with a spacer of known thickness gives a defined path length, so the Beer-Lambert law applies exactly as it does in ultraviolet work. A pellet's thickness and a mull's are not reproducible, and the fingerprint region gives no internal standard. Quantitative work needs a defined path length whatever the spectral region, and the sampling technique has to be chosen with that in mind.
