Quality control of silicones used in medicinal implants is challenging, and traditional methods waste a lot of raw material. In this study, NIR spectroscopy has been used to replace the traditional rheometric measurements, with excellent results. The NIR method enables improved quality control and a more economical process.

Infrared multiple angle incidence resolution spectroscopy (IR MAIRS) provides a powerful new tool to determine the molecular structure and orientation in a thin film on an IR-transparent substrate. The MAIRS technique replaces a tedious, and sometimes impossible, combination of sample preparation and analysis of identical films on both transparent and reflective substrates.

There is a continuing need for Fourier transform infrared (FT-IR) users to receive training in how to interpret the infrared spectra they measure. This new column will provide practical advice about how to do this. This first installment will present why this type of column is important, discuss some basic IR theory, and lay out a blueprint for future installments.
