  • 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 ...

  • A novel spectrometer design for process and handheld infrared spectral measurements

    Introduction Infrared spectroscopy offers many unique advantages for measurements within an industrial environment. Historically, the technique has been used for a broad range of applications from the composition of gas and liquid mixtures to the analysis of trace components for gas purity analysis. In cases where a well-defined method of analysis is involved, such as the measurement of ...

  • Case study - Monitoring landfill gas

    Infrared absorption Infrared absorption is usually the preferred method for measuring methane and carbon dioxide. Most gases absorb radiation in the infrared region. The wavelength of radiation that is absorbed is determined by the natural vibration frequencies of the molecule. These natural frequencies will depend on several factors. Thus different gas molecules have different natural ...

  • Professional Pest Manager Magazine

    In the last issue of Professional Pest Manager (PPM), we talked with western Sydney based pest manager, Greg Morrison, about his use of the Green Eye Termite Monitoring and Baiting Station. For this issue, we tracked down Greg, who operates Antibug Pest Control and his senior technician, Robert Guiffre, checking out a job which both men reckoned had become a major headache. The good news was that ...
