Czech Museum of Mass Spectrometry

HOW TO WEIGH A MOLECULE?

Imagine that you want to weigh a water molecule. You cannot just place it on a weighing pan because it certainly would not work. You need a much more sophisticated device called a mass spectrometer.

The first such instrument was constructed by J. J. Thomson in 1912. Since then, mass spectrometry has developed into a fascinating field with many practical applications.

Newborn screeningg, doping tests of athletes, analysis of pollutants, testing of new drugs or space exploration are only a few examples of the application of mass spectrometry. Yet there are many more.

Czech Museum of MS: Mass Spectrometer

MASS SPECTROMETER

A mass spectrometer is a remarkable instrument that provides information about the mass and structure of molecules. In essence, it is a very accurate scale for electrically charged molecules. However, such a scale does not resemble the traditional ones known from kitchens and pharmacies. It is an ingenious device that uses electric and magnetic fields to manipulate, separate and detect charged molecules. Some instruments also make it possible to break charged molecules into pieces, which is useful for deducing the molecular structure.

OUR MISSION

The museum aims to collect and display artifacts in mass spectrometry, especially those associated with our geographical region. Students professionals and the general public can look a the key components of spectrometers and understand how mass spectrometers work. The technical solutions and stories behind the exhibits can inspire young scientists as wall as experienced designers of scientific instruments.

EXHIBITION

The exhibition shows instrument components tha are often hidden in inaccessible vacuum chambers of mass spectrometers. You can take a closer look at them, understand their function, and at the same time admire their technical perfection and beauty. Use your smartphone to learn more about the exhibit you are currently viewing. The posters on the walls will teach you about mass spectrometry and its history.
