  • Precellys application focus forensic - case study

    Forensic laboratories working with hard samples such as hair [1, 2J, bone [3], teeth, skin, etc. experience difficulties with DNA extraction due to the high energy needed to grind these tissues. Moreover, biological evidence is available in small quantities and the current techniques used do not provide high quality results. The Precellys homogenizers provides high speed sample disruption based ...

  • Case study - Oklahoma crude oil forensic analysis

    An oil company used Sitelab’s laboratory to perform oil forensic analysis testing crude oils from different well sites to determine the percentage of oil content from two formations. The wells tap into these zones at different depths, thousands of feet below the ground. Knowing what type of oil being pumped is important. All six oil samples had similar GRO content, but the PAH content in ...

  • Forensic engineering of fire damaged concrete structures: state of the art

    All structures are likely to be subjected to elevated temperatures during an event of fire. Due to accidental thermal loads the structures may be subjected to cracking and that affect both the mechanical or structural properties. Even though total collapse of structure is rare, the structures or a part of it may suffer partial damage. Thus structures need to be thoroughly assessed in order to ...

  • Methodology for Forensic Investigation of Potable Water Quality in Municipal Distribution Systems

    Abstract During routine regulatory potable water quality sampling in distribution systems related to the Total Coliform Rule, utilities can sometimes experience anomalous detections of total coliform bacteria and/or fecal coliform bacteria in the distribution system samples. Frequently, the regulatory-required retesting of the same sample locations reveals no detection of bacteria, and thus ...

  • FORENSIC study at a Northern New Jersey service station: the mixing of old and new gasoline

    In 2000, a client purchased a gasoline service station in northern New Jersey. A few days after receiving possession of the property, he received a letter from a State regulatory agency informing him that an investigation surrounding a leaking waste oil UST was required. He was unaware that a waste oil UST had existed; automotive repairs were not part of his or the previous owner’s business ...

  • Reconstruction of a go–karting fatality

    Concession go–karts are recreational hire–vehicles with a unique and challenging set of crashworthiness requirements. A case study reconstruction of a fatal crash involving a female rider, that occurred at a speed of 25 km/h on an 'in–door' circuit, has revealed a number of crashworthiness issues that need to be considered by both designers and operators. Details of the forensic investigation of ...

  • The role of measurement uncertainty in doping analysis

    The determination of measurement uncertainty is a critical issue in all fields of experimental science; its importance becomes maximal in the specific case of forensic analytical chemistry (including doping analysis), where uncertainty has not only to be calculated with precision, but it also has to be both small and reliable enough to support effective decision making. This contribution gives a ...

    IntroductionThe detection and characterization of explosives has gained the interest of various analytical laboratories and researchgroups around the world.For the forensic community, trace analysis of explosive residues after arson and terrorism is of critical interest.Biologists and environmentalists monitor biotransformation of these high energy compounds when evaluating ...


  • A predictive approach of dynamic modulus for characterising Florida hot mix asphalt mixtures

    The dynamic modulus is one of the fundamental properties defining the response of asphalt mixtures in a flexible pavement system. It is an essential input of the Mechanistic–Empirical Pavement Design Guide (MEPDG) software for asphalt pavement design. Many studies have been done about the predictive model of dynamic modulus. This paper presents a comprehensive study about developing a predictive ...

  • Advances in flashpoint testing: economic impact

    Flashpoint testing is one of the oldest methods of the ASTM D02 Committee on Petroleum Products and Lubricants, which was formed in 1904. The most prevalent standards are ASTM D56 (Tag Method), D92 (Cleveland Method), and D93 (Pensky-Martens Method). These classical techniques, commonly referred to as open-cup and closedcup methods, share a common principle: A test flame is lowered into the ...

  • LC/MS/MS analysis of metabolites of synthetic Cannabinoids JWH-018 and JWH-073 in Urine

    Abstract A liquid chromatographic method was developed to resolve a comprehensive set of metabolites of JWH-018 and JWH-073. In addition to the chromatographic analysis method, an extraction method was developed to recover a broad range of synthetic cannabinoid metabolites, including carboxylic acid metabolites that are not traditionally recovered using a high pH liquid/liquid extraction. ...
