MULTI-DIMENSIONAL GAS CHROMATOGRAPH APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a multi-dimensional gas chromatograph apparatus capable of easily switching between a switching analysis and a single column analysis using a second detector. SOLUTION: The chromatograph apparatus includes: a first column 13 for separating components in a sample introduced from a sample introduction part 11; a first detector 17 for detecting the sample separated by the first column 13; a second detector 23 for detecting the sample separated by a second column 18; and a passage switching part 14 for switching the passage so as to send the sample passing through the first column 13 to either the first detector 17 or the second column 18. The chromatograph apparatus further includes a second sample introduction part 20 and a third column 21 for separating components in a sample introduced from the sample introduction part 20 and is configured so that the sample separated in the third column 21 is detected by the second detector 23.
