Introduction

Generally, microplastics are evaluated by observing their appearance, measuring their number and size, as well as qualifying the materials. Regarding the evaluation of the total number of particles, particle size distribution, shape, etc., we actively participated in data acquisition for standardization 1), and ASTM D8489 (hereinafter referred to as D8489) was published in 2023 2). D8489 focuses on smaller particles between the range of 5 - 100 µm and provides information on particle size, size distribution, concentration, and shape. On the other hand, infrared spectroscopy is a powerful method for evaluating the analysis of materials, and ASTM International is currently studying 1) for standardization. ASTM WK87463, which is currently under investigation, is expected to be a standard for evaluating microplastics by FTIR and LDIR (Laser Direct Infrared) for particles of 20 μm to 5 mm. In this article, we will introduce microplastic evaluation using iSpect DIA-10, a dynamic particle image analysis system in line with D8489, and microplastic material evaluation using FTIR.
