Gas Analysis with the Nicolet iS50 FT-IR Spectrometer

August 01, 2015

Combining a high precision FT-IR spectrometer with a long pathlength gas cell provides a powerful tool for analyzing trace levels of contaminants in air and other gas mixtures (Figure 1). Two important applications of this are ensuring air quality and the purity of breathing oxygen and compressed air.

Using Multivariate Curve Resolution to Identify the Evolved Gases Created During a TGA-IR Experiment

Thermal decomposition provides valuable information about the chemical composition of a material. Although thermal gravimetric analysis (TGA) measures small weight losses during a heating ramp, it cannot identify the chemicals corresponding to the weight loss.
