This application note describes the measurement of food macronutrients by diamond attenuated total reflectance (ATR) mid infrared spectroscopy. Specific examples include the measurement of sugar content of grapes (grape juice) and the measurement of fats in cheese, chocolate and milk.

Pharmaceutical material analysis is performed to confirm the purity and genuine composition of active pharmaceutical and additive ingredients. This report describes the integration of Attenuated Total Reflection (ATR) Fourier Transform infrared (FT-IR) spectroscopy with video microscopy observation of pharmaceutical materials.
