Portable Raman Analyzer (RamanID)
The RamanID is a portable, rugged, brief-case system weighing under 30 pounds, designed to travel and work in less-than-ideal environments. The system operates over a broad temperature range, and uses a military-grade, 5-hour rechargeable battery. Sample measurement is accomplished through the use of lightweight fiber optic probes that can be standalone or integrated into positioning systems, with fiber optic cables ranging from 3 to 25 meters in length. Samples can be identified through colored glass or plastic bags or bottles, eliminating the chance of exposure to possible harmful substances in such containers.

The RamanID is the only portable Raman analyzer that employs a rugged interferometer that provides 0.1 cm-1 wavenumber (x-axis) accuracy to guarantee correct spectral matching. Furthermore, each system is calibrated at the factory and never needs to be re-calibrated. Other portable Raman analyzers require frequent calibration.
The RamanID is also the only portable Raman analyzer that employs 1064 nm laser excitation to avoid fluorescence interference. All other portable Raman analyzers use shorter wavelength lasers to generate Raman spectra (e.g. 785 nm), which very often generate fluorescence in the sample. This is especially true for natural substances (biological materials, petroleum products, etc), as well as most improvised explosives, common street drugs, and food products that are sometimes used as anthrax hoax powders. If a sample fluoresces, the Raman spectrum is completely lost, which makes identification impossible. See the example in the figure below.

|
TNT fluoresces when excited with a 785 nm laser and the single dominant peak is insufficient information to ensure identification. Excitation with RTA’s 1064 nm laser produces an easily identifiable Raman spectrum.
|
Another key design feature is a rugged and extremely precise interferometer that ensures constant spectral resolution throughout the spectrum and precise wavelength assignment of detected peaks. Both of these features are key elements to ensure that spectral library matching is accurate and reproducible. Designed to meet military specifications, the RamanID is lightweight for true portability and will operate reliably even in adverse weather conditions.
