Perform reliable and repeatable FT-IR analyses of evolved gases and fumes from combustion.
Toxic fire effluents are responsible for most fire fatalities and a growing proportion of fire-related injuries, largely due to the widespread use of synthetic polymers and advanced materials. Fire safety standards traditionally focus on ignition prevention and flame spread reduction by limiting the rate of heat release, often underestimating the critical aspect of fire toxicity.

How it works
REDshift automated system extracts fumes generated inside a combustion chamber (from third party) using a filtering box. Then a heated transfer line carries the collected gases into the Long Path Cell (LPC) for FT-IR analysis. Main parts are: • The dedicated filter box prevents ashes and heavy particles from entering the circuit. • Automated controller with touchscreen display manages LPC sampling temperature, flow and pressure. • Programmable sequences - sampling, spectra trigger, loop washing with purge gas and calibration with standard, recording operational parameters ensuring accurate and repeatable analysis. • A dedicated data acquisition module interfaced with the FT-IR software, records operational parameters and quantitative data from IR analysis. • Calibration certificate - calibration curves determination for the most common analyzed gases [HF, HCl, HCN, CO, CO2, NO, etc…], following ISO 6143
