GC-MS & GC

  • GC-MS (Gaz kromatografisi - Kütle Spektrometresi)
    Working Principle 
    Gas chromatography / mass spectroscopy (GC-MS) is a combination of two powerful analytical techniques. Gas chromatography separates the components in the mixture. Mass spectroscopy assists in the structural identification of each component. It has important advantages such as identification of very small amounts of samples, strong structural analysis and fast analysis time. 
    The GC-MS system allows the determination of the elements in the multi-component mixtures by the mass chromatographic method of the organic samples in the gas phase or which can be gasified. It is a high performance and high speed gas chromatography mass spectrometer system used for qualitative and quantitative studies in advanced (organic, inorganic and biological) molecular structure determinations with the help of obtained spectra. All kinds of substances containing volatile organic compounds with sensitivity of ppm (one in million) and ppb (one in billion) can be analyzed in our devices.
    Marka: Shimadzu
    Model: QP 2010 Ultra
    GC-MS (Gas chromatography–mass spectrometry), GC-MS as an analytical device consists of two units: 
    1)Gas chromatography (GC) 
    2)mass spectrometry (MS) The GC-MS is also connected to Purge-Trap (liquid sample autosampler) and Headspace (solid sample autosampler).
    Volatile organic compounds are analyzed in the instrument. After the ionization in GC, the elements of the sample to be analyzed are sent to mass spectroscopy where they are separated according to mass / charge (m / z) ratios and qualitative and quantitative measurements are made. GC-MS uses He gas as the driving gas. Different detectors and gases used in our GC device are as follows;
    FID (Flame Ionization Detector): H2 and dry air
    FTD = NPD (Nitrogen Phosphorus Detector): H2 and dry air
    ECD (Electron Capture Detector): N2
    FPD (Flame Photometric Detector): H2 and dry air
    Usage areas
    It contains volatile gas and organic compounds;
    * Chemistry (Alkoloids, terpenes, steroids for analysis and separation of gases and volatile substances)
    * Pharmaceuticals industry (contents and dosage amounts of drugs)
    * Forensic and drug analysis
    * Qualitative and quantitative analysis of petroleum products can be done. The method is also frequently used.
    * Environment (drinking water, sea water, waste water, solid wastes)
    * Food (pesticide analysis in fruit and vegetables)
    * Food Aflatoxin analysis can be done.
