  • Infrared analysis of single and multilayer films in the production area

    There are many areas in production that can benefit from a rapid onsite measurement: determining which side is which on multilayer films to be laminated, checking rolls of film in the warehouse, measuring an individual layer within a film in the production area, raw material verification, and formulation discrimination are few examples. A new concept portable infrared spectrometer enables the ...

  • Measuring IR Light and Near-IR Light

    Infrared (IR) light emits a broad range of non-visible wavelengths in the electromagnetic spectrum. Applications for infrared, including near-infrared, are defined by the respective IR bands during output. For example, LIDAR (Light Detection and Ranging) equipment uses 1,000 nm and 1,550 nm IR bands while surveying an area. In the military sector, 850 nm, 1,060 nm and 1,500 nm (and up) are used ...

  • What is a Spectrometer?

    The characteristics of a white LED light differs greatly, when compared to a yellow CFL. Without any special tools, one can see that the LED emits a clear white color, while the CFL generates yellow light. Going one step further, using a spectrometer, one will be able to “dissect” the light sources and see that they are composed of other colors in the visible light spectrum, such as ...

  • Quantitative analysis of automotive exhaust gas by Fourier Transform Infrared spectroscopy

    For monitoring gaseous emissions from muffler, instruments presently used can only measure quantitatively a given pollutant. Fourier Transform Infrared (FTIR) spectroscopy can provide quantitative and online real time analysis. Calibration of our FTIR spectrometer with CO, CO2, NO, NO2 and N2O was done and the limits of quantification obtained were shown to be as low as 80 ppm. The variation ...

  • 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, ...

  • Get Comparable ASTM/EN Data for Biodiesel Blend Measurements While Saving Time and Money using Portable IR Analyzers

    Both EN 14078 and ASTM D7371 methods for measuring the percent biodiesel in diesel fuel use infrared analysis as the analytical method and are based around using an FTIR spectrometer which has the capability to do a multitude of analyses besides the biodiesel in diesel measurement. This is great for a laboratory where various biofuels measurements are required. However, if the only measurement ...

  • The importance of background in the Detection and Identification of Gas Plumes using Emissive Infrared Hyperspectral Sensing

    Abstract Using a Fourier transform infrared field spectrometer, spectral infrared radiance measurements were made of several generated gas plumes against both a uniform sky and terrestrial background. Background temperature, spectral complexity, and physical homogeneity each influenced the success of emissive infrared spectral sensing technology in detecting and identifying the presence of a ...

  • Microplastic Analysis Using the AIM-9000 Infrared Microscope

    Microplastics are minute pieces of plastic with diameters ranging from a few micrometers to a couple of millimeters. Microplastics have become a global environmental issue since they may adversely affect coastal and marine ecosystems and potentially harm the health of human beings. An FTIR spectrometer, in conjunction with an infrared microscope capable of easily analyzing minute samples, is ...

  • Hyperspectral thermal infrared line profiling for mapping surface mineralogy

    Abstract An airborne hyperspectral thermal infrared line profiling spectrometer (TIPS) has been developed by CSIRO and Fugro Airborne Surveys to measure and map surface mineralogies. TIPS is a spectrometer based on an FTIR instrument, recording radiance channel in about 100 channels in the 8 mm to 13 mm wavelength range from contiguous 10 meter pixels along the flightline, at a nominal ...

  • 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 ...

  • Analytical Devices for the Measurement of Water Vapor in the Natural Gas Process and Transmission Industry

    ABSTRACT The determination of water vapor (and water dew point) is crucial in the processing, custody transfer and transport of natural gas. High levels of water vapor in a natural gas stream can lead to a number of problems which include the formation of hydrates and the contribution to freezing and corrosion of plant and equipment. There are a number of ways of determining the water vapor ...
