The photopolymerization curing process of a UV-curable photopolymer was investigated using time-resolved Attenuated Total Reflection spectroscopy.

Accurate diffuse reflection spectra are obtained with an integrating sphere and compared to spectra obtained using two types of mid-infrared reflection accessories.

The IRIS monolithic diamond ATR accessory was used to investigate pure cellulose and cellulose propionate, using spectral band analysis distinguish each sample.

A dilute 2.5mM hexane in CCl4 solution was investigated with a 20-reflection ATR accessory, showing a 38x improvement in collection time over 1-reflection ATR.

An automated ATR accessory was used to detect methanol in ethanol. The spectral bands of methanol and ethanol were evaluated for varying methanol concentrations.
