Analytik announces a new era in handheld Raman materials identification systems with the launch of the SciAps Inspector series in the UK & Ireland. The new Inspector series offers a 785 nm or 1030 nm laser for users across the materials characterization spectrum.

The new generation of SciAps Inspector, the world's most powerful Raman handheld materials identification system, is now available. For more than ten years, Inspector Raman®, with its patented, free space platform, has evolved to meet expanding customer requirements. The innovative, redesigned portable Inspector series enables Raman material discrimination of a wider range of samples by eliminating unwanted sample and background fluorescence. This mobile platform transforms the user experience with simple and intuitive graphical user interface (GUI) on a high resolution display. Large material libraries and advanced pass/fail algorithms are supported with an embedded PC that can provide rapid-fire results. The Inspector 300 version is upgraded with elevated laser power and a low noise detector.

Longer wavelength laser excitation in Raman spectroscopy can be used to eliminate or mitigate the influence of competitive fluorescence that can overwhelm the Raman spectrum in lower excitation systems including 785 nm laser excitation. The Inspector 500 has demonstrated the effectiveness of longer wavelength excitation for explosives and pharmaceutical excipients.

Sacrificing Raman intensity is inherent in longer wavelength laser excitation, as 1/λ4, and is exacerbated with poor performance detectors at near infrared wavelengths. The Inspector 500 model overcomes this issue by utilizing binary materials and alloys of Group III-V compound semiconductors that have high quantum efficiency in the region of interest. This feature, coupled with SciAps' patented free space design, results in a very high efficiency system that provides quality Raman spectra on difficult samples, enabling the identification or qualification testing of samples that were once prohibited with 785 nm handheld systems.

The Inspector series supports advanced chemometric algorithm processing which is required for materials that are difficult to discriminate. Methods can be created with multivariate algorithms for pass/fail discrimination or simple correlation models can be created for searching material libraries.

Following SciAps's acquisition of DeltaNu, Analytik Managing Director, Ian Laidlaw, says "The integration of DeltaNu, former Analytik partner, allows SciAps to expand their "combined sensor" platform by offering a comprehensive range of Raman systems. It has also enabled SciAps to consolidate manufacturing into a single modern facility while increasing their IP portfolio with important patents in Raman technology."
