- AN-RS-040Trace Detection of DMT in Plant Matter
Modern recreational use of DMT (N,N-Dimethyltryptamine) is growing and although it is legally protected in some countries, new legislation attempts to reduce its abuse and associated adverse health effects. MIRA XTR DS from Metrohm Raman provides rapid and sensitive detection of DMT in the field.
- 410000025-A410000025-AIdentification 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. In recent years, Raman spectroscopy has been studied extensively for forensic fiber analysis because of the high selectivity of Raman signatures, non-destruction nature of the test, and the ability to conduct the analysis without any sample preparation. The Raman spectrum can be measured directly on fabrics or fibers mounted on glass slide with very little interference from the mounting resin or the glass.
- 410000004-A410000004-ARaman Spectroscopy in Archaeological Studies
Portable Raman spectroscopy is an invaluable tool in the study of archaeological sites, allowing for in situ analysis which minimizes the impact of such studies on important cultural sites. The flexibility of the use of a fiber optic probe and tripod-mounted video microscope with a light weight instrument reduces the need for sampling, and increases the ability to make representative measurements over what can be very large sample areas. The information content of Raman spectroscopy aids in the understanding of the materials used in the construction and restoration of important archaeological sites, and in understanding the degradation that is occurring which should aid in preservation and restoration work.

- 410000019-BQuantification of methanol in contaminated spirits with Raman
Methanol, often present in spirits prepared with industrial solvents like wood alcohol, can lead to blindness and even death when ingested. After an incident involving methanol-laced alcohol in the Czech Republic, they adopted Raman spectroscopy as the preferred method for identifying and quantifying methanol in contaminated spirits, following an exhaustive study using various screening tools. This Application Note discusses the reasons why Raman spectroscopy is the ideal choice for this application and shows a real-world example of Raman analysis of methanol-laced rum.

Handheld Raman spectroscopy enables rapid polymer masterbatch analysis, while Metrohm’s XTR® algorithm mitigates fluorescence interference for accurate additive identification.
- 410000059-BCharacterization of carbon materials with Raman spectroscopy
Raman spectroscopy is a valuable tool for the characterization of carbon nanomaterials due to its selectivity, speed, and ability to measure samples nondestructively. Carbon materials typically have simple Raman spectra, but they contain a wealth of information about internal microcrystalline structures in peak position, shape, and relative intensity.
- 410000013-A410000013-AFast and Selective Detection of Trigonelline, a Coffee Quality Marker, Using a Portable Raman Spectrometer
Portable Raman is used to quantify trigonelline, an alkaloid that contributes to the health benefits of some foods. A simple method to quantify the presence of diluted trigonelline in solutions using surface enhanced Raman spectroscopy is described. Portable Raman is a tool that could be used in quality control of food items such as coffee and quinoa.
