Mass Spectrometry Quiz

Double-focusing mass spectrometer
Time-of-flight mass spectrometer
Quadrupole mass spectrometer

Your answer:

Viking 1 carried two mass spectrometers, both equipped with double-focusing analyzers and electron ionization sources. The first spectrometer with a Mattauch-Herzog geometry was designed by Alfred Nier; it was intended to analyze the upper atmosphere of Mars. The second one with a Nier- Johnson geometry was part of the GC/MS apparatus designed by Klaus Biemann. It was used to analyze the regolith and the atmosphere at the landing site.

1.
John Zeleny was an American physicist whose work laid the theoretical foundations of electrospray ionization. He was born in 1872 into a family of immigrants from Europe. Where did his family come from?

2.
Joseph John Thomson (1856 - 1940), Nobel laureate in physics, is credited with the invention of the mass spectrometer, the discovery of the electron and isotopes of stable elements. A lesser-known fact is his father's profession. What was it?

3.
What ionization technique was used for the first sequencing of peptides by mass spectrometry?

4.
What is the trajectory of a charged particle moving perpendicularly to a uniform magnetic field in a vacuum?

5.
The quadrupole mass filter has been known since the mid-1950s thanks to the work of Wolfgang Paul. The motion of ions in a quadrupole field can be described by solving second-order differential equations. When were these equations solved mathematically?

6.
Which mass spectrometer was carried by the American spacecraft Viking 1 sent to the planet Mars in 1975?

7.
Josef Mattauch is known for the development of Mattauch-Herzog double-focusing mass spectrometer and his work on isotopes and atomic weights. His career is connected with the Kaiser Wilhelm Institute for Chemistry in Berlin. Do you know where he was born?

8.
How long would be a paper needed for printing a profile mass spectrum measured in the m/z 0 1000 range at a resolution of 50,000 at m/z 500 if the peaks were to be 1 mm wide at their half maximum? Let us consider a constant width of all peaks.

9.
What is the trajectory of a charged particle moving parallel to a uniform electric field in a vacuum?

10.
Lunar craters are usually named after scientists and explorers. One of the craters on the Moon is named after a prominent scientist in the field of mass spectrometry. Who is named after?
