For the successful design and operation of gas based particle detectors, one needs a good understanding of the drift properties of the deployed gas. This includes the drift velocity of electrons, their diffusion and the gas amplification in different electric and magnetic fields. This work presents simulations and precision measurements of the drift velocity vd in low electric fields (< 400 V/cm) for argon-based gas mixtures with up to two additives. The additives used are CH4, CO2, CF4, iC4H10 and H2.
