General Description
Thermo Scientific TruDefender FTi analyzer is a rugged, handheld FTIR system for rapid, in-the-field identification of unknown chemicals including explosives, narcotics, toxic industrial chemicals, precursors and more. The instrument brings the power of FTIR directly into the hazard zone, enabling the responder to analyze—and act—faster than ever before. The TruDefender® FTi device was built to meet the needs of first responders. It is ergonomically designed for easy use in Level A gear and rugged enough to withstand the rigors of field use.
Key Benefits: - Fast, accurate identification. Returns results in seconds. Onboard hazard database provides full safety and treatment information, further speeding appropriate response.
- Easy to use. Intuitive, menu-driven interface is consistent across instruments for fast training and proficiency.
- Built for field use. Certified to MIL-STD 810G for ruggedness including drop, shock, vibration and operation in extreme temperatures.
- Automatic mixture analysis. Enhances substance identification capability and eliminates the need for subtraction of spectra.
- Easy maintenance. Self-contained and requires no scheduled maintenance, calibration, warm up time or mirror alignment, and uses no consumables. -Embedded mobile phone technology allows users to send results directly from the hot zone via SMS text or email.
Technical Description
Fourier Transform Infrared (FTIR) Spectroscopy FTIR is an absorption spectroscopy technique where an infrared light is passed through the sample. Some wavelengths may be absorbed, while others merely pass through the sample unaffected. Specific molecular bonds absorb a specific amount of energy and these losses of energy correspond to the peaks returned in an analysis. FTIR absorptions are strong and provide outstanding and easily interpretable results for substances which contain polar covalent bonds. FTIR spectroscopy is best used as a primary analysis technique for identifying colored substances such as industrial dyes, pigments and oils, and fluorescent materials.
