Thermo Scientific™ Gemini™ Chemical Identification Analyzer
Description
Identify a broad range of unknown chemicals and explosives in the field quickly, safely, and confidently using FTIR and Raman spectroscopy in a single instrument, including low concentration analysis.
Accuracy and reliability with advanced algorithms
The Gemini™ analyzer combines both Raman and FTIR technologies in a single handheld instrument, enabling complementary testing on scene. Leveraging advanced algorithms and a comprehensive onboard library, it supports the accurate identification of unknown solids and liquids, including explosives, chemical warfare agents, and industrial chemicals. Features like onboard mixture analysis and 24/7 reachback support reinforce operator confidence.
Ease of use for field operations
Designed for operators who work under pressure, Scan Assist technology guides users through sampling and technology selection, while customizable profiles assist the user with minimizing user error. Features like the motorized anvil and Scan Delay enhance safety by allowing operators to maintain distance from potential hazards. With intuitive workflows and a compact form factor, the Gemini™ analyzer reduces the burden of heavy equipment while increasing operational efficiency.
Add-on
Hazmaster G3: Integrated HazMasterG3® decision support software helps operators interpret results and assess potential threats from identified chemicals, supporting actionable insights directly in the field.
LowDoseID: By utilizing the enhanced hardware and software of the Gemini™ analyzer, combined with SERS, the Gemini™ analyzer with LowDoseID enables low concentration analysis and results for key narcotics.

Frequently Asked Questions (FAQs)
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.
