Identify a broad range of unknown chemicals and explosives in the field using FTIR and Raman spectroscopy in a single instrument, including low concentration analysis. The rugged, compact Thermo Scientific™ Gemini™ analyzer meets the demanding requirements of elite military and public safety forces, helping operators execute their mission quickly, safely, and accurately.

The Gemini Analyzer is the first and only integrated Raman and FTIR handheld instrument in the world, providing complementary and confirmatory testing in a single, field-portable device.


Better, faster decision making

  • Lightweight and compact, ideal for chemical battalions, explosive ordnance disposal (EOD) technicians and other first responders burdened with heavy equipment.
  • Virtual mixture analysis and interactive problem solving on scene with HazMasterG3.
  • Includes 24/7 reachback support with access to Ph.D. spectroscopists for spectral analysis and operational inquiries.


Increased confidence in results

  • Leverages both Raman and FTIR technology to address a broader range of samples than either technique alone.  
  • Identifies unknown solids and liquids, from explosives and chemical warfare agents to industrial chemicals and precursors using a comprehensive onboard library. 
  • Builds on the field-proven performance of Thermo Scientific™ FirstDefender™ and Thermo Scientific™ TruDefender™ Analyzers.


Safer operation

  • Includes a motorized anvil which adjusts sample pressure based on user settings.
  • Features Raman and FTIR Scan Delay to allow users to leave the hazard zone before initiating a scan.


Easier to use, enhanced efficiency

  • Guides the operator through technology selection and sampling with Scan Assist.
  • Customizable Profiles allow the operator to set scan parameters based on the sample, scenario and their situational awareness
  • Minimizes user error and eliminates subjective user interpretation.
  • Requires minimal training for proficiency.

Frequently asked questions (FAQs)

What is Raman spectroscopy?

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.

Do you offer support for the Gemini Raman and FTIR Chemical Analyzer with LowDoseID?

With an active support plan, Gemini products include 24/7, 365 reachback support with access to Ph.D. spectroscopists for spectral analysis and operational inquiries. Go here (https://portables.thermoscientific.com/gemini-customer-support-login) to access the Gemini customer support login page, where you can locate your Gemini serial number and support code, find contact information, access safety data sheets, ISO 9001 certificates, and warranty information, view parts and accessories, and log in to the download center.

How accurate is the Gemini Raman and FTIR Chemical Analyzer with LowDoseID?

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.

How easy is it to operate the Gemini Raman and FTIR Chemical Analyzer with LowDoseID?

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.

How portable is the Gemini Raman and FTIR Chemical Analyzer with LowDoseID?

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.
