ABSTRACT:
The components present in the sample with a mobile phase A in 1st section is separated. In 2nd section there is provided with an inserting line of a dilute solution for diluting the mobile phase A and a trapping column which forces the dilute solution to pass but catches the components by connecting said line to said column. In 3rd section, the components caught by the trapping column are introduced into mass spectrometer by using a mobile phase B. It is preferable to use respectively different mobile phases for the mobile phase A and the mobile phase B. It is good to install separating columns in 1st and 3rd sections. It is also desired to add the retaining apparatus of the components separated in 1st section.
