Optimizing the Workflow for Microplastic Analysis by FT-IR Microscopy

Introduction

Microplastics are becoming a major global environmental concern with plastics and microplastics turning up in everything and everywhere - including consumer products, especially food and beverages, and even within the digestive systems of marine species. Analysis of environmental samples containing microplastics is essential to determine their prevalence and their impact. A range of analytical techniques have been applied to the analysis of microplastics. Of the techniques adopted, infrared (IR) spectroscopy, and more specifically IR microscopy, is the primary analytical technique for the detection and identification of microplastics.
