  • Identification of forensic fabrics using a portable Raman spectrometer

    At a crime scene, a police officer collects a fiber sample that may prove to be invaluable evidence in identifying a criminal or exonerating an innocent person. While FTIR has been used for analysis in the past, the strong absorption of the fabric or the glass slide where it is mounted makes the spectrum very hard to interpret. In recent years, Raman spectroscopy has been studied extensively for ...

  • Rapid raw material identification for formulation compounds using handheld Raman technology

    Ever since the European Medicines Agency (EMA) recommended that all pharmaceutical companies test every raw material that passes through their manufacturing facilities, this practice has attracted great interest in the nutraceuticals, food manufacturing, cosmetics, and agricultural industries, pushing them to strive for more rigorous and technology-oriented quality control standards. In recent ...

  • Simple and sensitive detection of cyanide using pinhole shell-isolated nanoparticleenhanced Raman spectroscopy

    Cyanide is a great threat to public health, environmental safety and homeland security because of its extremely high toxicity and widespread usage in industry. Countering such a threat can be greatly aided by a rapid, sensitive, on-site detection method. Here, a pinhole shell-isolated nanoparticle-enhanced Raman spectroscopy (SHINERS) technique for cyanide sensing has been established, and a ...

  • Mixture analysis using reverse searching and non-negative least squares

    The portable even handheld Raman spectrometer can provide adequate spectral resolution for material identification in situ. Raman spectra are information rich but not easy to interpret, especially for the spectra of mixtures. The ability to identify components in the mixture is, therefore, of considerable interest and challenge. In this study, a promising solution for rapid mixture identification ...

  • Removal of lead(II) and copper(II) from aqueous solution using foitite from Linshou mine in Hebei, China

    Foitite from Linshou mine in China's Hebei province was investigated as an adsorbent to remove Pb(II) and Cu(II) from aqueous solution. The results showed that foitite can readily remove heavy metal ions from aqueous solution. The data shows that the metal uptake for Pb(II) increases rapidly, accounting for 74.47% when contact time was 2 min. In contrast to Pb(II), there was a worse capability ...
