Mass spectrometry is one of the analytical research methods included in spectroscopic methods. The method is based on calculating the ratio of mass to electric charge of a particular ion. The prepared samples of the test substance are analyzed in specially adapted devices called mass spectrometers. There are many variations of this technique that are used in various fields of science.

When was mass spectrometry born?
The history of mass spectrometry dates back to the end of the 19th century. It was then that the English physicist Joseph John Thomson began research on the conduction of electricity through gases. They led to Thomson's discovery of the electron, for which the physicist received the Nobel Prize in 1906.

Thomson is also credited with creating the prototype of modern mass spectrometers. Initially, the device, designed by an Englishman in 1911, was used only to affect ions with an electromagnetic field, which caused the studied ions to deflect the flight path. Depending on the mass-to-charge ratio of an ion, it was characterized by varying degrees of deviation. Currently, only some mass spectrometers use the idea of the Thomson device. Over the years, the technology has evolved in many directions, resulting in the creation of several different mass analyzers designed for completely different applications. However, they all have one thing in common — they allow you to measure the ratio of ion mass to charge.

Advantages of using mass spectrometry in analytical research
The use of mass spectrometry for analytical laboratory tests has many advantages. This method is extremely effective because it allows you to obtain not only very accurate, but also reproducible test results in a short time.
The greatest advantages of mass spectrometry are, of course, the accuracy of determining the molecular weight and chemical composition of a substance in a tested sample. More importantly, this technology allows for such measurements even in complex matrices where the test substance is just one of hundreds or even thousands of other substances. The development of ionization methods has made it possible to calculate the mass using mass spectrometers not only of gaseous substances, but also of liquid and solid substances, which significantly expands the possibilities of using this technique.

In what fields is mass spectrometry applicable?
Mass spectrometry is a modern analytical method used in many scientific fields. More than 100 years after Thomson's research, mass spectrometers are becoming an indispensable laboratory tool for physicists, chemists, biologists, and scientists conducting research in space.

Thanks to modern technologies and innovative solutions introduced by mass spectrometer manufacturers, these devices can be successfully used for:

Conducting qualitative and quantitative research on food analysis.
Perform accurate environmental analysis to detect trace amounts of dangerous compounds in test samples.
Conducting a forensic medical and laboratory examination of drugs.
Conducting research and diagnostic tests.
