The IR spectra of a number of standard polymers, such as polytetrafluoroethylene (PTFE), polystyrene (PS), polypropylene (PP), and polyethylene (PE), are shown in Figure 1. The PerkinElmer Spectrum ...

When a plastic absorbs IR radiation, it produces a spectrum representative of its molecular ... bag sample was identified (using the spectral library) as high-density polyethylene (HDPE) with a 94% ...

Polyethylene, or PET ... Just as fingerprinting uniquely identifies a person, scientists use spectroscopy to determine the chemical identity of microplastics. In spectroscopy, a substance either ...

Here, Po-Chun Hsu, Yi Cui and colleagues explored an existing nanoporous polyethylene (nanoPE), evaluating whether it would allow IR-radiation to pass through, and thus make a likely cool clothing ...

PerkinElmer Inc. has announced the launch of two spectrometers, the Spectrum™ 100 FT-IR and 100N FT-NIR, at the Eastern Analytical Symposium and Exposition, Garden State Convention Center, Somerset, ...
