PURPOSE:To enable the sampling and analyzing of an object to be inspected without adding dilution water even in the case of a limited amount of a sample, by injecting a hydrophobic liquid into an insufficient sample on the bottom of a container. CONSTITUTION:When a limited amount of a sample is left in a sample container 21, a control section 13 drives a hydrophobic liquid pump in a sampling device 8 to distribute a hydrophobic liquid in a storage tank 9 into the container 21. Being larger in the specific gravity than water, the hydrophobic liquid settles onto the bottom to form a lower layer while a sample forms an upper layer to obtain a clear division of layers. Then, with the sampling mode entered, the device 8 sucks and samples a specified amount of sample to be transferred to an analysis section. Thus, even a limited amount of sample can be analyzed without adding any dilution water. |
