We have recently been working on the quantification of hexadecanoic acid and octadecanoic acid.
We used a Cary 630 FTIR and Dialpath 200 μm photometry.The quantitative peak is 2855nm
The first graph shows the superimposed spectra of 25mg, 4mg, and solvent
The second graph shows the 4mg, 0.4mg, and solvent stacking spectra
Is there anything I can do to enhance the response of 0.4mg hexadecanoic and octadecanoic acids?
