Multilayered glitter particles were cut with a microtome into thin cross-sections and examined using an FT-IR microscope with a synchrotron infrared source. The high brightness of the synchrotron source enabled high-quality infrared spectra to be quickly obtained from individual layers in the glitter particle cross-section, providing additional chemical information that could increase the glitter particle's value as associative evidence in criminal cases.
多层闪光粒子被切片机切成薄片，然后使用具有同步辐射红外源的傅里叶变换红外显微镜进行检查。同步辐射源的高亮度使得能够从闪光粒子截面的各个层快速获得高质量的红外光谱，提供了额外的化学信息，这些信息可以增加闪光粒子在刑事案件中作为关联证据的价值。
