“…As mentioned, previous studies have used LIBS to analyze skid marks, 5,6 while LDA has been broadly used in forensics with PCA. [21][22][23] However, no known study has specifically used PCA-LDA to classify tire skid marks from LIBS data.…”

“…Studies have also shown that even with a nonvisible skid mark, some material is still left in the form of tire trace and could be analyzed for composition. 5,6 While anti-lock brakes do reduce the prevalence of skid marks, the extreme conditions of a car accident or similar situations could still cause a car to produce skid marks or leave tire trace.…”

“…With a forensic application in mind, two studies have used laser-induced breakdown spectroscopy (LIBS) to detect skid marks based on the higher concentration of Zn on a road section. 5,6 Even though analysis was done quantitatively with cross-analysis using inductively coupled optical emission spectrometry (ICP-OES), it was not focusing on the identification of the marks or their classification.…”

Tire evidence is a form of trace evidence that is often overlooked in today's forensics, while frequently found at crime or accident scenes, usually in the form of skid marks. The pattern of the tire skid mark has been used before to link a tire or car to a scene, but the widespread use of anti-lock braking systems makes this an almost impossible and abandoned route of analysis. With this is mind, using the chemical profile of a tire has potential to link a car or tire back to a scene in which its trace material is found. This study shows the successful use of the elemental profile of tire rubber to classify thirty-two different samples by Laser-Induced Breakdown Spectroscopy (LIBS), analyzed by Principal Component Analysis (PCA) combined with Linear Discriminant Analysis (LDA). A classification accuracy close to 99% shows the ever-growing use of LIBS as a technique of choice for forensic analysis of tire rubber, opening the path for its use as a forensic evidence.

“…Background was subtracted for each LIP spectral variable individually. The background value was estimated as the mean of a narrow wavelength range in close proximity to spectral line or molecular band, this approach is described in detail in our former work 29 . The obtained intensities of analytical signals were then averaged and further processed.…”

We present a report on the potential use of the Laser-Induced Breakdown Spectroscopy (LIBS) technique for direct investigation of Mg corrosion and related optimization of the table-top LIBS system. Moreover, the preliminary study to prove the capability of this LIBS technique for the estimation of corrosion grade is given.In order to simulate the real corrosive environment, Mg samples were prepared in a constant climate chamber. We show that the corrosive layer on the sample surface significantly affects the properties of laser-matter interactions, i.e. among other parameters causing the matrix effect. Consequently, the properties and persistence of laser-induced plasmas (LIPs) and their composition, generated on such degraded surfaces, essentially differ. Collected radiation of LIP is then analysed and ratios of ionic to atomic Mg spectral lines are correlated with the grade of magnesium corrosion, i.e. content of Mg(OH) 2 on the sample surface. The content of Mg(OH) 2 is also correlated with plasma temperature as well as with the electron number density of LIP. Additionally, X-ray diffraction (XRD) analysis and optical profilometry were utilized to obtain more comprehensive information about the degradation grade of high purity Mg samples.
