  • 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?

    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).

  • 2.
    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?

    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.

  • 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?

    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.
    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?

    Your answer:
    Correct answer:

    His father, Joseph James Thomson, ran an antiquarian bookshop founded by Thomson’s great-grandfather. [Wikipedia]

  • 5.
    Who first reported the fragmentation after the gamma hydrogen rearrangement to an unsaturated group via a sixmembered intermediate?

    Your answer:
    Correct answer:
    It was first reported by Australian A. J. C. Nicholson in 1954 (Trans. Faraday Soc. 50: 1067-1073). The reaction description was published five years later (Anal. Chem. 1959, 31: 82–87) by the American chemist Fred McLafferty, by whose name we now refer to the rearrangement (McLafferty rearrangement).

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

    Your answer:
    Correct answer:

    Chemical ionization was discovered in the laboratories of the Humble Oil and Refining Company in Baytown, TX. Munson and Field’s seminal paper on chemical ionization was published in 1966.  [https://doi.org/10.1021/ja00964a001]

    Who built the first mass spectrometer in Czechia?

    Your answer:
    Correct answer:

    The first mass spectrometer in the country was built in the Laboratory of Physical Chemistry of the Czechoslovak Academy of Sciences. Four young scientists, Vladimír Čermák, Vladimír Hanuš, Čestmír Jech and Josef Cabicar, took part in its construction. At the time of the post-war shortage, it was very difficult to find the necessary components; some parts originated from captured German military equipment. The mass spectrometer was of the Nier type with simple focusing and 60° magnetic field, pumped by a mercury diffusion pump. The device was completed after two years, in 1953. The construction of this instrument was an extraordinary achievement awarded a year later by the State Prize. [Z. Herman, Chem. Listy 104, 955, 2010]

    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?

    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.

  • 9.
    How many elements of the periodic table have only a single stable isotope?

    Your answer:
    Correct answer:
    These so-called monoisotopic elements are beryllium, fluorine, sodium, aluminum, phosphorus, scandium, vanadium, manganese, cobalt, arsenic, rubidium, yttrium, niobium, rhodium, indium, iodine, cesium, lanthanum, praseodymium, europium, terbium, holmium, thulium, lutecium, rhenium, and gold.

  • 10.
    What ionization technique was used for the first sequencing of peptides by mass spectrometry?

    Your answer:
    Correct answer:

    Mass spectrometry was used to sequence peptides for the first time in 1959 when K. Biemann described an innovative method based on the reduction of small peptides to polyamino alcohols with characteristic EI spectra. [https://doi.org/10.1021/ja01518a069]
