Moles quantification in liquid samples by Raman spectroscopy

• We showed a general equation that can help us to quantify any type of specimen using the Raman technique (macro-configuration).
• We have noted an excellent correlation between the experimental and expected data.
• This work presents a math relationship that relates directly the Raman signal to the amount of sample studied.

The mole is a unit of measurement that expresses amounts of a chemical substance. Its importance lies in that the mass and the number of molecules of a substance can be determined with this value. In this work, we suggest a mathematical expression that relates the number of moles of the sample studied with the Raman signal and the experimental parameters used. In other words, with this mathematical expression it is possible to obtain quantitative information in a simple manner from Raman spectra. We have applied this method to different samples and we have observed an excellent correlation between the experimental and expected data.
