Mass Spectrometry Quiz

1.
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?
- Berlin, Germany
- Ostrava, Czechia
- Klosterneuburg, Austria
Your answer:

Correct answer:

Josef Mattauch was born in 1895 in the city of Mährisch Ostrau, in what is now the Czech Republic, then part of the Austrian-Hungarian Empire.
2.
What was the largest number of quadrupoles connected in series for tandem mass spectrometry in a commercial instrument?
- 5
- 7
- 9
Your answer:

Correct answer:

A penta-quadrupole mass spectrometer contains three quadrupole filters and two rf-only quadrupole collision cells. It allows MS³ experiments. Extrel once offered such a spectrometer.
3.
The first on-line coupling of gas chromatography to a mass spectrometer was reported in 1959. What type of spectrometer was used for this purpose?
- Double-focusing mass spectrometer
- Time-of-flight mass spectrometer
- Quadrupole mass spectrometer
Your answer:

Correct answer:

The first GC/MS experiments were carried out by Fred McLafferty and Roland Gohlke at Dow Chemical with Bill Wiley and Ian McLaren at Bendix Research Laboratories. They used a Bendix timeof- flight mass spectrometer, which had been commercially introduced in 1956. The instrument was fast enough to keep up with the changing output of the GC column.
4.
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?
- 1868
- 1968
- 1989
Your answer:

Correct answer:

The solution of differential equations of this type came from the French mathematician Émile Léonard Mathieu (1835-1890), who studied the mechanical vibrations of the elliptical drumheads.
5.
Which mass spectrometer was carried by the American spacecraft Viking 1 sent to the planet Mars in 1975?
- Double-focusing mass spectrometer
- Time-of-flight mass spectrometer
- Quadrupole mass spectrometer
Your answer:

Correct 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.
6.
What is the trajectory of a charged particle moving parallel to a uniform electric field in a vacuum?
- The particle follows a curved path and continues to follow this path until it forms a complete circle
- Neither the trajectory nor the velocity of the particle changes
- The particle either accelerates or decelerates, depending on the field direction and the particle charge sign
Your answer:

Correct answer:

If a positive charge is moving in the same direction as the electric field vector the particle's velocity will increase. If it is moving in the opposite direction it will decelerate. If a negative charge is moving in the same direction as the electric field vector the particle will decelerate. If it is moving in the opposite direction it will accelerate.
7.
Until 2019, the kilogram unit was defined using an international prototype kept at the International Bureau of Weights and Measures in France. The International Prototype of the Kilogram was made of an alloy of platinum and one other metal. The metal was:
- Gold
- Iridium
- Rhenium
Your answer:

Correct answer:

The International Prototype of the Kilogram was a cylinder with a height and diameter of 39 mm made of an alloy of 90% platinum and 10% iridium.
8.
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?
- Slovakia
- Czechia
- Poland
Your answer:

Correct answer:

The parents of John Zelený, Antonín Zelený and Josefa Pitková, came from Křídla, a small village near Žďár nad Sázavou in Austria-Hungary (now the Czech Republic).
9.
What is the electric charge of an ion with m/z = m?
- 1 C
- 1.602 176 634 x 10^-19 C
- 1 eV
Your answer:

Correct answer:

The particle carries one elementary charge, the value of which is 1.602 176 634 × 10⁻¹⁹ C (exactly).
10.
List these compounds according to their increasing mass: hydrazine (H4N2), oxygen (O2), methanol (CH4O).
- Hydrazine, oxygen, methanol
- Methanol, hydrazine, oxygen
- Oxygen, methanol, hydrazine
Your answer:

Correct answer:

The monoisotopic masses of these compounds are 31.989829 Da (oxygen), 32.026215 Da (methanol), and 32.037448 Da (hydrazine).
