The OM data shows that the LDPE sample is particularly polydisperse -quantified by large differences between each weighted average. The most numerous size range is 1 µm -2 µm, with the frequency decreasing approximately inversely with increasing size range. The size distribution obtained by LD follows the behavior of the microscopy data until the 5 µm region, after which, it under-reports the smallest particles greatly. This is likely due to the limitations of LD discussed earlier, with the LDPE sample being highly polydisperse and asymmetrical.
