Here’s some more information about Unknown Substances/Materials
Identifying an unknown material is a crucial task in many unknown identification investigations, as it can help determine the cause of a loss or damage. Armstrong Forensic Laboratory is a certified testing laboratory that has a team of seasoned experts specializing in chemical analysis and material identification. By using sophisticated instrumentation and techniques, the laboratory can accurately identify unfamiliar substances and provide clients with the information they need to make informed decisions.
One of the methods used by Armstrong Forensic Laboratory to identify an unknown material is Fourier transform infrared spectroscopy (FTIR). This technique involves shining an infrared light on the sample and measuring the energy absorbed by the molecular vibrations. The spectrum obtained from the measurement provides a unique fingerprint that can be compared with a library of over 1000,000 spectra. FTIR is a non-destructive, rapid, and sensitive method that requires a small amount of the sample.
In addition to FTIR, Armstrong Forensic Laboratory offers other analytical methods for material identification, such as X-ray defraction, gas chromatography-mass spectrometry (GC-MS), inductive coupled plasma (ICP), optical emission spectrography (OES), and atomic absorption spectroscopy (AAS). GC-MS is used to separate and identify the components of complex mixtures, while ICP, OES and AAS is used to determine the concentration of metals in the sample. The selection of the appropriate method depends on the nature of the material and the questions to be answered.
In conclusion, identifying an unknown material is a complex and challenging task that requires a combination of expertise, instrumentation, and techniques. Armstrong Forensic Laboratory is a licensed testing laboratory with decades of experience in chemical analysis and material identification. Its team of experts uses state-of-the-art equipment and methods to accurately identify unfamiliar substances. By providing reliable and timely results, Armstrong Forensic Laboratory helps clients in insurance investigations make informed decisions and resolve their claims.
