Abstract

Apparatus for sampling a liquid, said apparatus comprising:i) a sampling device capable of automatically taking a known volume of liquid from a source;ii) fixing means connected to said sampling device and removably attachable to a solid phase extraction (SPE) unit, the fixing means being arranged such that liquid taken from a sample by the sampling device is passed directly through the solid phase extraction unit;iii) a reading device able to read labels on an SPE unit attached to said fixing means;iv) a controller arranged to log codes based upon a signal from the reading device, and thereafter issue instructions to an operator and/or operate the sampling device to take an appropriate volume of liquid in response to a signal from said reading device.Methods of sampling using the apparatus are also claimed. These are useful in, for example analysis methods.
