The Midwest Laboratory for Microplastic Research (MLMR) is utilized for research conducted at NIU and collaborates with other academic and non-academic clients. Our laboratory is equipped with an Agilent 8700 Laser Direct Infrared (LDIR) Chemical Imaging System which uses quantum cascade laser (QCL) imaging technology. LDIR provides a research-grade method for spectral analysis and chemical imaging that advances our ability to detect microplastic (MP) particles, determine their size and acquire detailed information about their chemical composition. LDIR enables efficient and accurate detection, characterization, quantification, and identification of MPs in sizes between 20 μm and 500 μm.
To address potential interferences by non-plastic particles from the samples, the Clarity software MP library contains various spectral data of non-microplastics (e.g., naturally occurring polyamide, chitin, cellulosic materials, carbonates and stearates which are commonly present in environmental samples).
The instrumentation applies to research in environmental sciences, anthropology, agriculture, pharmaceuticals, biology and biochemistry, public health and beyond. Sample types include water, soil, dust, biologic material, human biospecimens, Quality assurance and quality control protocols are completed regularly to ensure accuracy and precision.
| Samples | Collaborators | NIU and Illinois Innovation Network (IIN) | External academic and Federal agencies | External private industry |
|---|---|---|---|---|
| Environmental (water, soil, sediment, air, dust) Sample processing, extraction, and LDIR analysis | $200 | $250 | $350 | $500 |
| Extracted (ready to run) Sample filtered on 25 mm 0.8 μm pore size gold coated filter or prepared in ethanol for low e-glass slide for LDIR Analysis | $50 | $50 | $50 | $100 |
The above calculation is based on samples with less than 1,000 particles. These charges will be increased $50 per 1,000 particles. Extra fees may apply if other services are required. For commercial work, add appropriate sales tax. Please contact the lab for any questions or concerns.
