When comparing lattice calculation to experimental data from heavy ion collision experiments, the higher order fluctuations of conserved charges are important observables. An efficient way to study these fluctuations is to determine them from simulations at imaginary chemical potential. In this talk we present results up to the eighth order derivative in muB, calculated on a 48^3x12 lattice with staggered fermions using different values of muB while muS=muQ=0.
