PURPOSE:To make a chromatogram easy to see by printing a component name correctly at the peak position of the recorded chromatogram in a real time even when attenuation and a speed are varied even in the middle of analysis. CONSTITUTION:A CPU 5 reads an elapsed time (t) and a detected intensity signal X(t) during measurement and when the read signal X(t) has a peak value, the CPU stores the signal X(t) as a peak value H(I) and its elapsed time (t) as a peak detection time T(I) (I: detected peak number) in an area R(a). When the signal X(t) is not within a set attenuation value ATT(J), the attenuation is varied to such a value ATT(J) that the signal X(t) is smaller than a value ATT(J), and a value TT(J) and a variation time TA(J) are stored in an area R(b). Then, the signal X(t) is stored in a printer plotter 4. When the measuring operation is finished, identification is carried out by a table data fie for identification stored in the area R(b) according to the peak value H(I) and time T(I) stored in the area R(a). |
