Abstract: A sampling apparatus for sorptive sampling comprises a sample vessel, a sorbent sample probe and an actuator such as a robotic arm. The sample vessel is arranged for containing a liquid to be sampled. The sample probe has a probe section including a sorbent material configured to be inserted into the sample vessel. The probe section includes a sorbent material arranged to acquire analytes from the sample vessel. The actuator is configured to connect to and manipulate both the sample vessel and the sample probe independently. The sample probe is detachably connectable to the actuator such that the actuator is able to connect to and detach from the sample probe in use to selectively interchange the sample probe connected to the actuator with a further sample probe.
