The invention relates to a sampling apparatus and method. In the sampling method, a sample is led through a flowline (20) to a pump (5) and from there on to sampling means (12, 13). According to the invention, the pump (5) is formed of an actual pump (5) and magnetic valves (4, 6) located on either side of it, which are controlled in such a way that the pumping is pulse-like.
