Mass spectrometry is an analysis technic for detecting and identifying molecules of interest by measuring their average or mono-isotopic mass.
Different elements make up a spectrometer:
- An introduction system to receive the sample, which will differ according to its nature (in the case of gas chromatography for example)
- An ion source, also called an ionization chamber
- An analyser, which differentiates ions on their mass-to-charge ratio, based on the movement of ions, kinetic energy, and the magnetic field
- A detector, which identifies the ions leaving the analyser
The mass spectrum obtained represents mass-to-charge ratio of the ions detected. Depending on the preferred type of ionization (chemical, electronic, thermal, etc.), you will then be able to identify, structurally analyse and quantify the molecules present.
HTDS offers a wide range of mass spectrometry solutions such as GC-MS and GCMSMS, LC-MS and LCMSMS, QTof spectrometers, but also isotopic ratio mass spectrometers.

LCMSMS Triple Quadrupole
Triple quadrupole mass spectrometry allows precise quantification by confirming traces of analytes in complex samples. Whether they are pollutants, metabolites, pesticides or narcotics, this ultra-sensitive technique is made to detect the greatest number of analytes in various types of samples.
Isotope-ratio mass spectrometry
Isotopic ratio mass spectrometers have been acclaimed since the 2000s for obtaining precise isotopic reports in fields such as forensic medicine, environmental, pharmaceutical and food analyzes, or even doping screening in the sports. HTDS offers you a full range of IRMS to adapt to your most complex applications.
Gas chromatography - Mass spectrometry (GC-MS) is a method that combines both the efficiency of gas chromatography and amss spectrometry in order to accurately identify or measure the number of substances. The GC-MS method introduced in the 1950s has developed considerably and is now fully mastered. It is now under computer control and relatively simple to set up, the devices being now autonomous and compact. For quantitative analysis, it is very easy to obtain very precise and exact results thanks to the great dynamic response, the speed of analysis is also very fast.
LC-MS is now used for many applications and suffers a real essort because of its power, its very high sensitivity and selectivity and its coupling facilities with technique separative analysis. The LC-MS devices are also very efficient and reliable devices with a specific technology for each application. The applications are numerous and mainly towards the detection and overall potential identification of chemicals in the presence of other chemicals. LC-MS particular plays a fundamental role in environmental analysis, drug screening, chemical and pharmaceutical research, medicine...
Qtof is a mass spectrometry technique for detecting and identifying molecules of interest by measuring their monoisotopic mass. The Qtof technique makes it possible to precisely measure the monoisotopic mass of an ion and to deduce its gross formula. The Qtof spectrometers allow an analysis after ionization. This technique is used in practically all scientific fields: physics, astrophysics, chemistry in the gas phase, organic chemistry, dosages, biology, medicine ...
