Mass Spectrometry Quiz

1.
What was the largest number of quadrupoles connected in series for tandem mass spectrometry in a commercial instrument?

2.
What is the trajectory of a charged particle moving perpendicularly to a uniform magnetic field in a vacuum?

3.
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?

4.
What is the electric charge of an ion with m/z = m?

5.
What is the trajectory of a charged particle moving parallel to a uniform electric field in a vacuum?

6.
Chemical ionization (CI) is a soft ionization technique used in mass spectrometry. Who discovered it?

7.
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?

8.
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?

9.
Mass spectrometers known as calutrons were used for the industrial separation of uranium isotopes during the Manhattan Project. A large amount of copper was needed to make their magnetic coils. How was the highly-valued metal obtained during the war?

10.
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?
