The FTIR spectra were carried out with a Tensor-27 instrument (Bruker, Ettlingen, German) in the wavenumber range 4000–500 cm−1, and the resolution was 4 cm−1 over 32 scans at room temperature. The rABS, rH
These findings demonstrate the importance of accurate adhesive identification in planning successful treat- ments and the value of using portable analytical equipment for identifying adhesives otherwise not detectable using standard visual and ultraviolet fluorescence examination methods....

A thin layer of transparent polystyrene treditimatly been used as an infrared spectroscopy standard. This is the lightweight material of which coffee cups and ...
Further evidence of biodegradation is the observed decrease in intensities of peaks characteristic for PS and the appearance of carbonyl groups (CO stretch, 1700 cm− 1). The broadening of peaks at 2500–3500 cm− 1 in all FTIR spectra of frass samples is associated with the hydrogen bond...

SEM, XRD, and FTIR offered insights into the nature of the composite. The results indicated that graphenes were well dispersed and embedded throughout the PS matrix to form an interconnected conducting network. The performance of this unique graphene-based detector has been demonstrated by separating...

Easy to use, they simply slip into the standard sample holder of any FTIR instrument. These references are produced under Starna’s ISO 17034 Reference Material Producer accreditation and certified under ISO/IEC 17025 for Calibration. More information online...
most published studies relying on FTIR for polymer identification8. Due to their small size, MPs can be easily confounded as food particles by many marine organisms, such as zooplankton, fish, mammals and specially by filter-feeder organisms such as bivalves9,10,11,12. In marine bivalves, ...
[152]. Therefore, the actual photodegradation of the solid sample might be higher than measured by FTIR [152]. From controlled weathering experiments, it has been estimated that a rate of only 5% formation of defects on the surface of a PS microparticle occurs annually [164], but for deeper...
