Tire traces – Discrimination and classification of pyrolysis-GC/MS profiles

Detection of tire tread particles using laser-induced breakdown spectroscopy

“…a dactyloscopic foil, is highly suitable for collection of tire tread particles. The use of an adhesive tape for handling or collecting the powder samples was described, for example, in [19][20][21] and the use of a dactyloscopic foil for collection of tire tread particles from the road surface was described, for example in [5].…”

“…4). The particle size and morphology described in literature proofs differ depending on the particles origin from 10 μm to 300 μm [3,5]. Particles made in the above-mentioned manner were weighed and spread on an adhesive tape (dimensions: 20 × 15 mm 2 ).…”

“…One of them is their detection on the basis of identification of polymers. For example, Gueissaz and Massonnet used pyrolysis in combination with gas chromatography and mass spectrometry (Py-GC/MS) [5] for detection of tire tread particles. Another example of a method used for detection of tire tread particles on the basis of typical polymers is, for example, infrared spectrometry (IR) [6].…”

Pyrolysis Gas Chromatography–Mass Spectrometry for the Characterization of Tire Marks for Forensic Analysis

“…The results obtained using pyrolysis gas chromatography delivered information enabling the identification of rubber traces. Only two studies, made by Sarkissian (2007) and Gueissaz and Massonnet (2013) were focused on the analysis of rubber marks left by the tires of a braking vehicle. Sarkissian (2007) examined the correlation between chromatograms of samples taken from tires and rubber marks left on the concrete road using a combination of LDA and PCA methods.…”

“…All samples in that work were collected using tweezers from concrete substrate. The application of statistical methods to tire traces classification has been also recently published by Gueissaz and Massonnet (2013), who analyzed ten tires and corresponding traces left on the asphalt surface collected using lifting tape.…”
