  • 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 ...

  • Evolved gas analysis - the study of materials using a Thermogravimetric Analyser (TGA) coupled to a Mass Spectrometer (MS)

    Thermogravimetric Analysis (TGA) of materials is commonly used to provide information on the weight loss as a sample is heated or held isothermally. Pharmaceutical materials often show weight losses associated with the loss of solvent/ water, desolvation or decomposition of the sample. This information is then used to assess the purity and stability of the material and its suitability for use. ...

  • Emissions analyser helps manage power station

    A multiparameter emissions monitor at Thetford power station is being used to demonstrate to the Environment Agency that the plant is performing within the conditions of its environmental permit. However, the data from the analyser, which was supplied by Milton Keynes based Quantitech, also performs a vitally important role in helping to manage the plant. “Individual gas readings are ...

  • Quantitative Determination of Volatile Organic Compounds in Drinking Water by EPA Method with Headspace Trap GC-MS

    Volatile Organic Compounds (VOCs) refer to a group of easily vapourised organic compounds. Under atmospheric pressure, these compounds boil below 250C. Studies have shown that prolonged exposure to the VOCs could increase the risk of various health problems, such as cancer. VOCs are commonly present in gasoline, dry cleaning solvents and degreasing agents. Due to improper storage, disposal or ...

  • Passive sampling for target and non‐target analyses of moderately polar and nonpolar substances in water

    The applicability of silicone rubber and low density polyethylene (LDPE) as passive sampling materials for target and non‐target analyses of moderately polar and non‐polar substances was assessed through a field deployment of samplers along a small polluted stream in Oslo (Norway). Silicone and LDPE samplers of identical surface area (but different volumes) were deployed at six sites in the ...
