Multilayer Film Analysis Using the AIMsight Infrared Microscope

Download

User Benefits

- AIMsight allows the user to view the target area while recording its IR spectrum. - AIMsight can measure the thickness of thin films in wide-field camera images and microscope camera images. - A mapping function can be used to create chemical images for visualization of the distribution of constituent materials.

Introduction

One of the roles of films in food and pharmaceutical packaging is to maintain product quality. These films often have multiple layers, combining single-layer films to offer a variety of properties such as heat resistance, impact resistance, light shielding, and oxygen barrier properties, depending on the contents of the product. Determining the material and thickness of each layer in a multilayer film is important for the development of new film materials and quality control. This analysis can also be used for comparisons with competitor products and to study competitor products. Infrared microscopes can be used for qualitative analysis of target areas in the range of 10 to several 100 μm, and thus are suited to the analysis of multilayer films. The AIMsight infrared microscope comes equipped with a length measurement function and a Spectrum Advisor Function (patent pending). The length measurement function measures the distance between any two user-selected points on images captured by AIMsight (more details below). The Spectrum Advisor Function uses interactive prompts to check for phenomena that could cause errors during measurement, thus allowing users with limited analytical experience to determine if a recorded spectrum is of good or poor quality. More information about the Spectral Advisor function can be found in Application News 01-00456-EN. This article describes an example of application of the AIMsight length measurement function being used to analyze multilayer films for confectionery packaging.
