SEL Number: 07CD-01-DPRS
Title: Detector, Raman Spectroscopy, Point


Last Updated: 6/23/2022 3:15:32 PM

Previous SEL Number: 07CD-01-DPRS

Description: Point chemical detector utilizing Raman spectroscopy. These detectors may also have explosive detection capability when equipped with appropriate spectra libraries. See Item 07ED-01-LASR.
DIQCode: [D,I]
[Note: Replaces 07CD-01-DPFR.]

ImportantFeatures: Identifies solids and liquids.

Systems are available using a variety of wavelengths (785 nm, 830 nm, 1064 nm, etc.) and techniques (spatially offset Raman spectroscopy, surface enhanced Raman spectroscopy, etc.).

Operating Considerations: Prior to procurement, be sure to evaluate library content as the system will only be as useful as its library.  Expect a cost increase of approximately $1/spectra added.

Warning: The intensity of some lasers and scan duration are sufficient to ignite some explosive compounds. Darker solids such as black power or silver azide are most susceptible to ignition. Do not measure suspected energetic materials on filter paper or other flammable bases. Exercise caution in explosive environments or with large samples. Use appropriate personal protective equipment when testing. Check manufacturer's web site periodically to obtain latest technical and safety bulletins.

Warning: Laser glasses or a safety enclosure required with some products. Consult user manual for details.

Often used in conjunction with FTIR device to provide increased confidence level, [see 07CD-01-FTIR].
Visible, tangible sample needed for identification. Does not identify vapors.
Additional expense may be involved in purchasing / maintaining libraries.
Results may be unreliable at extreme high or low temperatures - check user manual for operating temperature limitations. ICostRating: $$$/$$$$
