The aim was to not only determine how many particles were present, but to assess any differences due to the methods used. Counting of extracted microplastics was undertaken using particle size analysis, light microscopy and imaging flow cytometry. Micro Fourier transform infrared spectroscopy (µ‐FT‐IR) was used to characterize the particles in each product. The mean size distribution of microplastics differed depending on the method employed and it was apparent that imaging flow cytometry was affected by high background noise that may require staining of plastics to overcome. The application of µ‐FT‐IR confirmed polyethylene as the microplastic in each product.
