# Determination of Urea and Hydrogen Peroxide in Cow Milk by ATR-FTIR(Attenuated total reflection-Fourier Transform Infrared Spectroscopy) [closed]

I am doing a research on cow milk adulteration. I am checking Urea and Hydrogen Peroxide content in milk by ATR-FTIR(Attenuated total reflection-Fourier Transform Infrared Spectroscopy). I am using $\ce{1M}$ Urea solution and $\ce{1M}$ Hydrogen peroxide solution. I am adding this to cow milk and testing through FTIR. But i am not getting good IR peaks of $\ce{H2O2}$.

Should i dilute the solutions? As we know, UV spectrophotometer gives better peaks at dilution. But in case of IR what should i do to get better peaks? what concentration of $\ce{H2O2}$ should i use?
