STRam
Portable Raman analyzer for rapid analysis and identification of samples through opaque packaging – no sample preparation needed.
The STRam is a “See-through” portable Raman system with rapid material identification capabilities through a variety of barrier layers and packaging previously impenetrable by Raman spectroscopy. The STRam provides easy identification of materials through a variety of packaging and barrier layers utilizing 785 nm or 1064 nm wavelengths.
- Rapid, nondestructive material identification through opaque packaging
- Sample and packaging integrity are maintained, limiting operator exposure
- Compact, robust design including embedded tablet computer
- Compliant with 21 CFR part 11 requirements
See-through sample identification
Using our patented STRaman technology, the STRam and STRam-1064 can collect Raman signals generated underneath diffusive top layers to identify material inside visually opaque barriers such as plastic bottles and multi-layer paper sacks while maintaining package and sample integrity.
The system design unites a high-throughput spectrometer, specialized sampling optics, and advanced materials identification algorithms in a compact Raman system.
- Minimize exposure to samples and possible contamination by identifying the sample inside its packaging
- Measure through white and light-colored plastic containers, paper and fiber sample bags
- Create tailored spectral libraries for rapid identification of your samples in their original packaging
- Easy measurement with fiber-optic sampling probe with adaptors for optimal spectral data collection
- Benefit from a large sampling area, and large sample penetration depth for reliable results
Compact design and easy sampling
The compact STRam system with embedded tablet computer makes it easy to move it and set it up wherever you need it.
Achieve large sampling depth for measurement through packaging using this high-throughput spectrometer system coupled with its specialized sampling probe design. The STRam is operated with 21 CFR part 11-compliant identification software for rapid, secure identification and results reporting. The software has a logical workflow to guide the user through the measurement.
The STRam can be used for incoming material identification, and for package inspection by postal service, and custom agencies to detect potential hazards and controlled materials.
