The award-winning STRam^® portable Raman system delivers rapid material identification capabilities through a variety of barrier layers and packaging previously impenetrable with Raman. The system design unites a high throughput spectrometer, specialized sampling optics and advanced algorithms in a compact Raman system with embedded tablet computer. The STRam and STRam-1064, operating with 785 and 1064-nm Raman excitation respectively, can identify materials through multiple layers of packaging to meet your application needs.

With our patented technology, you can use the STRam to identify samples inside opaque packages. The STRam collects Raman signal generated underneath diffusive top layers so you can identify material inside visually opaque barriers such as white plastic bottles, paper envelopes, tablet coatings, and highly fluorescent Kraft paper. This removes the need to open containers and have any direct exposure with the material, thus maintaining package and sample integrity, and increasing operator safety.

The STRam design features a large sampling area and sampling depth and minimized power density, so you can measure samples that can be challenging for conventional focused Raman spectroscopy.

SENSITIVE:

The system design enhances the signal at a greater depth so that samples inside opaque containers can be identified without the signature of the top layers overwhelming the sample signature. The system combines a high-throughput spectrometer, a high sensitivity and low noise detector, a specialized sample probe, and advanced identification algorithms.

VERSATILE:

The system provides versatility for see-though measurements through barriers and across a large sampling area while allowing low power density in measuring sensitive samples. Specialized adaptors can easily be attached for focused measurement directly on a sample. The STRam can be used for Raman analysis of samples ranging from those in packages to sensitive energetics or biological samples, and its large spot size gives greater reproducibility of heterogeneous sample measurements.

TOUCH SCREEN INTERFACE:

The STRam is a fully integrated system with a tablet computer running 21CFR part 11 compliant software for through-barrier-layer material identification. With optional battery operation for easy portability, the system provides research-grade, high-sensitivity Raman capabilities wherever needed.

B&W Tek offers comprehensive software packages that provide solutions for Raman application needs. Powerful calculations, easy data management, and user-friendly, easy-to-follow workflows are all at the tips of your fingers.

The STRam is controlled by 21 CFR Part 11 compliant BWID®-Pharma software optimized for rapid identification and verification of materials, and includes advanced STID algorithms for through-package identification. BWID®-Pharma provides enhanced system access security, secured data storage, and an audit trail of data activities. IQ and OQ services are available.

In the laboratory, the system can be connected to an external computer and used with the BWSpec® software, the foundation for all B&W Tek software platforms, offering full acquisition control, continuous monitoring and additional analysis capabilities and viewing options.

B&W Tek’s software portfolio also includes BWIQ®, a multivariate software package for qualitative and quantitative analysis of spectral data. BWIQ includes chemometric methods such as Partial Least Squares Regression (PLS), Principal Component Analysis (PCA) and Support Vector Machine (SVM) regression, a full suite of preprocessing tools, and extensive graphics for model interpretation. Models can be used for real-time predictions from BWIQ directly. The BWIQ chemometrics software package is ideal for analysis of spectroscopic data.
