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

1. Mobile Laboratory

At the request of the DMSB e.V, Stegner & Klaus Engineering have developed and produced a mobile laboratory for analysis and examination of fuels, particularly racing fuels, tyre inflation gases as well as rubber samples from tyre surfaces of racing tyres.

This mobile laboratory consists of the following equipment:

> Gas chromatograph (GC for the examination of the rubber and the fuel)
> Electronic injector (permits a direct examination of rubber in the GC)
> Automatic sampler (for an automatic injection of fuel into the GC)
> Hydrogen generator (for the production of the H2 to run the equipment)
> Hydrogen sensor (for the supervision of hydrogen leakages of the stove in the GC)
> Zero air generator (for production of pure air to run the equipment)
> Air compressor (for operation of the GC system)
> Printer (for documentation)
> Mobile computer (for the evaluation of the analysis)

With this laboratory an analysis and examination of fuels, racing tyre surfaces as well as of tyre inflation gases is possible while still at the circuit. The laboratory is designed for transportation with motor vehicles or by airfreight (under consideration of compliance with the dangerous goods regulations). The complete equipment is installed in four Flight-Cases (55 cm, 60 cm, 65 cm, B, H, T, weight approx. 230 kg), which can be unpacked into two columns to form the laboratory. With this equipment, the analysis described above can be performed in almost any location. (See picture)
