- 410000003-A410000003-APortable Raman Spectroscopy for the Study of Polymorphs and Monitoring Polymorphic Transitions
Raman spectroscopy is used for material characterization by analyzing molecular or crystal symmetrical vibrations and rotations that are excited by a laser, and exhibit vibrations specific to the molecular bonds and crystal arrangements in the molecules. Raman technology is a valuable tool in distinguishing different polymorphs. Examples of portable Raman spectroscopy for identification of polymorphs and in monitoring the polymorphic transiton of citric acid and its hydrated form are presented.
- 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.

- 410000009-A410000009-ARapid Identification of Heroin with Handheld Raman
Raman spectroscopy is used widely by law enforcement as a field screening tool due to its speed, selectivity and ease of use. The majority of materials can be identified by the Raman signature, as they exhibit sharp distinctive peaks serving as a molecular fingerprint. However, many street and real-world samples are dark in color and not pure. The dark color, often due to impurities, gives rise to fluorescence that interferes with the Raman measurement. One method to suppress the fluorescence of a sample and enhance the Raman activity / signal is by the use of Surface-Enhanced Raman Spectroscopy (SERS).
- 410000012-A01410000012-A01Rapid Detection of the Low Dose API in Xanax Using Surface-Enhanced Raman Spectroscopy for Anti-Counterfeiting Purposes
The emergence of counterfeit prescription drugs has become a concern for the pharmaceutical industry. Because of the low concentrations of APIs found in pharmaceutical drugs, normal Raman spectroscopy is typically not sensitive enough to detect the API from the surface of a pill. In this study we develop a surface-enhanced Raman spectroscopy (SERS)-based approach to identify a low-dose of the API alprazolam in a Xanax tablet using a handheld Raman spectrometer. If no SERS peaks consistent with alprazolam are observed from a Xanax tablet, the pill is a suspected fake. The method demonstrates the power of SERS to quickly verify the presence of alprazolam in the tablet for anti-counterfeiting purposes.
- 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.
