Answer the following about the year 1957 in analytical chemistry, for 10 points each.
[10h] The flame ionization detector overshadowed this scientist’s 1957 electron capture detector, which made the first observation of atmospheric CFCs. In 1955, this scientist used an early tabletop microwave to thaw rats.
ANSWER: James Lovelock [or James Ephraim Lovelock]
[10e] The newly-minted van Deemter (“DAYM-ter”) equation described how packing a column affects the ability of this process to proceed turbulently via eddies. This process’s namesake coefficient relates flux to the concentration gradient.
ANSWER: diffusion [or word forms of diffuses or diffusing; accept diffusion coefficient; accept eddy diffusion]
[10m] In gas chromatography, Marcel Golay provided an alternative means of finding the height equivalent to these entities. These entities quantify the efficiency of a separation process and correspond to real objects in distillation.
ANSWER: theoretical plates [or theoretical trays; accept height equivalent to a theoretical plate; accept equilibrium stage; prompt on plates or trays or HETP]
