Assuring quality in microplastic monitoring: About the value of clean-air devices as essentials for verified data

Abstract Avoiding aerial microfibre contamination of environmental samples is essential for reliable analyses when it comes to the detection of ubiquitous microplastics. Almost all laboratories have contamination problems which are largely unavoidable without investments in clean-air devices. Theref...
