GAS CHROMATOGRAPHY TECHNIQUES: APPLICATIONS IN THE AREA OF FUELS AND THEIR DERIVATIVES
A 1975 NASA technical report by A. Galtieri on gas chromatography methods applied to fuels and their derivatives, issued for researchers and laboratory analysts. The illustration is a line-drawn chromatogram: a flat baseline broken by tall narrow spikes and low rounded humps, each numbered 1 through 10, printed in black on white with visible reproduction speckle \u2014 usable as spiky graph silhouettes, data-trace motifs, or rhythmic vertical marks.
