Mass spectrometry

Mass spectrometry is a device that produces ions from atoms, molecules, radicals, or mixtures thereof, and then separates and identifies these ions according to their mass/charge (m/e) ratios. 

A mass spectrometer consists of the following parts:

  •          The section where the sample is fed to the device
  •          Ionization part
  •          Mass selective quadrupole part
  •          Detector
  •          Software and computer


Areas of use of Mass Spectrometry

  •          Determination of structures of organic and biochemical molecules;
  •          Determination of molar masses of peptides, proteins and oligonucleotides;
  •          Identification of separated substances in thin layer and paper chromatography;
  •          Determination of amino acid sequence in polypeptide and protein samples;
  •          Identification of substances separated by chromatography and capillary electrophoresis;
  •          Determination of toxic substances and metabolites of these toxic substances in blood, urine and mouth water;
  •          Monitoring of gases in the patient's breath during the operation;
  •          Determining the ages of archaeological samples;
  •          Doping control in race horses and Olympic athletes;
  •          Analysis of aerosol forming particles;
  •          Determination of pesticide residues in food;
  •          Monitoring of volatile organic substances in water sources, etc

 

The main advantages of Mass Spectrometry:

  •          Having high sensitivity;
  •          The presence of versatile fields of application;
  •          Being able to give quick results;

 

Mass spectrometry (MS) is a powerful analytical technique that measures the mass-to-charge ratio (m/z) of ions. It offers unparalleled insights into the composition and structure of molecules. When combined with gas chromatography (GC-MS), it allows for the separation and identification of complex mixtures.

 

  • Structural Analysis in Chemistry: Elucidate the structure of complex molecules using mass spectrometry.
  • Biomolecular Characterization: Accurately determine molecular weights and sequences of proteins and peptides with mass spectrometers.
  • Environmental and Forensics: Detect trace contaminants and identify substances with precision using automated mass spectrometry techniques.

 

  • The Versatility of Mass Spectrometry: From pharmaceutical research to environmental monitoring, mass spectrometry offers wide-ranging applications.
  • Choosing the Right Mass Spectrometer: Explore factors like resolution, sensitivity, and ionization methods to find the ideal mass spectrometer or mass spectrometre for your needs.
