Thermo Electron Corp.'s Nicolet Compound ID portable infrared analyzer is an easy-to-use instrument that provides fast, nondestructive classification of materials under extreme conditions. This allows first responders to identify hazardous materials on-scene. This device has been tested for use while wearing protective gear, including Level A suits and SCBA gear. The analyzer operates in a Hazmat restricted areea warm zones while its lightweight removable sampling module (SealR) lets the responder enter the hot zone. The unknown sample can then be contained within the Seal IR. Mutiple Seal IR modules can be used for simultaneous sampling when time is critical. A simple software interface guides the responder through the analysis of unknown materials.
