Current methodologies for microplastic polymer identification such as FTIR and DSC are neither cost efficient nor practical in fieldwork. Density analysis is an inexpensive and readily transportable alternative method. However, current density analysis methods use many different hazardous solutions to carry out separation and identification of plastics. Here, we demonstrate the use of water, sucrose and ethanol solutions for the density analysis of microplastics. The method developed was able to successfully distinguish between and identify eight polymers commonly found in microplastic pollution.
