Abstract
The present invention relates to a pretreatment apparatus that performs concentration and separation of a sample, and in particular, in order to provide a sample pretreatment apparatus using a solid-phase extraction column, and a mass spectrometer using the same, which is particularly suitable for clinical analysis in which qualitative/quantitative analysis of a biological sample such as blood is performed, according to each operational step for a solid-phase extraction treatment, for example, a collection device serving as flow passages or containers for collection of waste liquid or extracted matter is installed on a bottom face of the solid-phase extraction column, and the extracted matter is separately collected without being mixed with waste liquid by switching the positions of the collection device.
