Gemini™ Chemical Identification Analyzers

In Raman spectroscopy, an unknown sample of material is illuminated with monochromatic (single wavelength or single frequency) laser light, which can be absorbed, transmitted, reflected, or scattered by the sample. Light scattered from the sample is due to either elastic collisions of the light with the sample's molecules (Rayleigh scatter) or inelastic collisions (Raman scatter). Whereas Rayleigh scattered light has the same frequency (wavelength) of the incident laser light, Raman scattered light returns from the sample at different frequencies corresponding to the vibrational frequencies of the bonds of the molecules in the sample.

The Gemini Raman and FTIR Chemical Analyzer with LowDoseID produces clear results, with no subjective interpretation. The instrument includes a comprehensive library of over 14,000 chemicals (both solids and liquids), and features best-in-class algorithms and automatic mixture analysis.

The intuitive interface of the Gemini Raman and FTIR Chemical Analyzer with LowDoseID ensures quick training for first-time users and continued proficiency for experienced operators. The Scan Assist feature helps new users select the most appropriate technology with a few simple questions.

In addition, there is a large tactile keypad, a resistive touch screen designed for use while wearing gloves, an integrated Raman probe, motorized FTIR anvil, and flexible power options, among other user friendly features that cater to both experts and non-experts in the field.

Weighing less than 2 kilograms, the Gemini Raman and FTIR Chemical Analyzer with LowDoseID is easily transported downrange or into the hazard zone, reducing the logistical burden of carrying two separate technologies and increasing efficiency with confirmatory identification capability when and where it is needed. By providing sophisticated technology in such a compact, lightweight device, one no longer needs to sacrifice capability for weight, giving an unparalleled advantage in the field.
