In a standardization method used alongside this technique, a series of n-alkanes is given an index equal to 100 times the number of carbons they have.
One quantity important in this technique is calculated in a linear fashion by the Van del Dool and Kratz equation. An inverse version of this technique is commonly used to measure the surface energy of solids. In a standardization method used alongside this technique, a series of n-alkanes is given an index equal to 100 times the number of carbons they have. In this technique, an inert carrier flows into a column oven attached to an autoinjector; the sample then passes into a (*) flame ionization detector. This technique, which uses a retention index named for Kovats, is commonly used before mass spectrometry of simple molecules in intro organic chemistry classes. For 10 points, name this form of chromatography in which the analyte is in a vapor phase.
