Next Generation Handheld Raman Analyser Accommodates Wider Range of Samples
Analytik has announced the new generation of SciAps Inspector, one of the world’s most powerful Raman handheld materials identification systems. For more than ten years, Inspector Raman, with its patented, free space platform, has evolved to meet expanding customer requirements. The Inspector handheld analyser is an easy to use device, with point-and-shoot operation for countless quality control and verification applications. The device can be used anywhere — the field, the factory floor, a warehouse, loading dock or laboratory.
Advanced users can also create their own libraries of compounds and customise matching and correlation criteria. The 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 a 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 µm laser excitation. The Inspector 500 has demonstrated the effectiveness of longer wavelength excitation (1030 µm) for pharmaceutical excipients, for example, samples consisting of complex molecules or samples with a number of impurities.
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 utilising 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 µm handheld systems.
