Chiral quark models with non-local covariant separable interactions at finite temperature and chemical potential are investigated. In particular we study the chiral phase transition for some definite non-local regulators. We find that in all cases the transition is of first order for low values of T, turning into a smooth crossover at a certain “end point”. Predictions for the position of this point are given.
