Application Note: Material Analysis by Infrared Mapping: A Case Study using a Multi-Layer Paint Sample
6 Mar 2013
Agilent’s Cary 610 FTIR Microscope provides the ability to collect high quality chemical information from multi-layer samples with a high spatial resolution. In this application note, a 380 × 380 μm infrared map was automatically collected using a pre-defined acquisition grid to investigate the chemical heterogeneity of a paint chip sample. Four chemically distinct layers were resolved in the forensic evidence, including a miniscule layer measuring ~40 μm.
