Title: Sample preparation for the determination of microplastics in suspended particular matter (SPM) from surface water, considering different target values

This standard operating procedure (SOP) described sample preparation techniques for the identification microplastics in suspended particular matter (SPM) using mass determination techniques, such as Thermal Extraction Desorption – Gas Chromatography/Mass Spectrometry (TED-GC/MS) or Pyrolysis – Gas Chromatography/Mass Spectrometry (Py-GC/MS) and particle determination techniques, such as Micro Fourier Transform Infrared Spectroscopy (µ-FTIR) and Quantum Cascade Laser Laser Direct Infrared (QCL-LDIR).
