Analysis of Fuels, Tyre Surfaces and Tyre Inflation Gases at the race-track with a Mobile Gas Chromatograph System "mobilab"
by Karl-Heinz Stegner and Eugen Klaus

2. Fuel Analysis

2.1 Fuel Sampling
A reference sample is taken from the specified fuel. At a suitable place the fuel from the racing vehicle is directly taken from the fuel system by a tube and put into a fuel-tight locking container. Three (3) samples are taken. One sample is examined on the spot, a second one is given to the organizer and the third sample stays with the racing team.
2.2 Test Method
The reference sample and the samples out of the racing vehicle are examined in the gas chromatograph. In the GC the fuel mixture is separated into its individual components and each component is shown in a chromatogram. The evaluation is made by comparing the reference sample to the samples from the racing vehicle like a finger print. Changes or contaminations of the fuel are shown in the different chromatograms.
