Sample preparation for infrared imaging multilayer film measurement using the SliceMaster

There are various devices that can create cross-sections of multi-layer films for analysis of the molecular structure using infrared spectroscopy. To date, cross sections of multilayer laminates have been created by embedding the sample in epoxy resin and then using a microtome to create the cross-section slices. This technique has various drawbacks, including the time required for the resin to harden (several hours for epoxy resin) as well as resin contaminating the sample. In addition, since the IRT-7000 infrared imaging system can dramatically shorten measurement times compared to conventional imaging measurement systems, the need to reduce the time required for preprocessing samples was required. For the creation of cross sections, the SliceMaster developed by JASCO, was used. This accessory can provide thin slices or cross sections of various samples, including multi-layer laminates, without embedding them in resin.

In this experiment, the vertical SliceMaster (HS-1) was used to create a cross-section from a food package that was measured using the transmission method of analysis.
