The NRS-4500, a Raman microscope, can measure the small samples that have a size of around one micrometer. These samples can be placed in the microscope using a glass slide.
The plastics for this measurement are microplastics that were collected in the South Florida area. These samples were washed to avoid any influence or in the measurement.
The laser that we use is 785. This can produce less fluorescence. Actually, we also use less power so this decreases the chance of damaging the sample.
