  • FTIR Spectroscopy

    Fourier Transform Infrared (FTIR) Spectroscopy bases its functionality on the principle that almost all molecules absorb infrared light. Only the monatomic (He, Ne, Ar, etc) and homopolar diatomic (H2, N2, O2, etc) molecules do not absorb infrared light. Molecules only absorb infrared light at those frequencies where the infrared light affects the dipolar moment of the molecule. In a molecule, ...

  • FTIR gas analysis improves container safety

    Introduction Entry to freight containers represents a significant hazard to staff responsible for inspection, stuffing or destuffing because of the large number of airborne chemicals that can be present. Research in Germany and the Netherlands found hazardous levels of gases and vapours in around 20% of all containers and this level of contamination is now accepted as commonplace. It ...

  • IRGAS XFlo: process gas FTIR system for flange mounted applications

    Introduction When doing process tool or exhaust abatement tool installations, it is desirable to monitor the exhaust gases as a means of controlling or setting up the tool 1, 2. FTIR, with its rapid analysis speed, high sensitivity, and ease of use, offers one means of monitoring such systems at the time of installation and during the working life of the tool. Often, these applications ...

  • FTIR gas analyzers support management of fire at UK waste facility

    The capability to convene a multi-agency Air Quality Cell (AQC) was established in England in 2009 following the Buncefield Oil Storage Depot incident. A review of this event identified the need to rapidly co-ordinate the acquisition, analysis and interpretation of air quality data in major incidents.  Arrangements have been made in England to bring together experts from the Environment ...

  • High-sensitivity, fast-response monitoring of PFC and abatement tool emissions by FTIR spectroscopy

    Semiconductor fab plants are faced with real-time monitoring and reduction of their PFC emissions to meet SEMI Environmental, Health and Safety (EHS) requirements. In some cases emissions are continuous, while in other cases they are intermittent or random. Also, in-situ real-time process control is becoming a critical element of yield enhacement. Solution: FTIR Spectroscopy In-Situ ...

  • Comparing TGA, FTIR and fixed filter infrared analyzers for measuring soot levels in in-service lubricants

    Measuring soot in diesel engine oil has become more important as soot levels get higher due to exhaust gas recirculation. As soot isone of the key indicators for the condition of the oil, diesel engine maintenance programs performing regular soot checks can realize cost savings by extending drain periods and reducing used oil disposal. TGA (Thermal Gravimetric Analysis) is the traditional method ...

  • Exoscan FTIR instrument system can easily be used in the lab or taken to the field for routine analysis.

    Infrared spectroscopy has long been recognized as a selective and sensitive technique for analysis and characterization of surfaces. From material identification to quantitative analysis, infrared analyses can establish if a surface is composed of the correct material, has the proper coating thickness, is free of contaminants, is properly cured, or has the correct properties for the next step in ...
