Therefore, although the component separation by the column is in two stages, the data output from the detector is data of one system in time series order. Therefore, by plotting the data thus obtained in the order of generation, it is possible to create a chromatogram similar to normal GC, that is, a chromatogram having the horizontal axis as the time axis and the vertical axis as the signal intensity axis.

Therefore, according to this two-dimensional chromatogram, it is easy to understand the properties of each compound, and many compounds Even if it is contained, it is possible to easily grasp what kind of compound is contained.
- data obtained by analyzing a sample in a comprehensive two-dimensional GC is temporarily stored in a storage device such as a hard disk, and then the data is read out from the storage device at an appropriate time, and dedicated data as described above.
- a storage device such as a hard disk
- the process of collecting data from a comprehensive two-dimensional GC and storing the collected data in a storage device is not for a comprehensive two-dimensional GC, but using ordinary GC or GC / MS software. Done.
- the collected chromatogram data does not include data (parameter information) indicating the modulation time, which is one of the analysis conditions.

- functions other than the modulation time estimation unit 24 in the GC ⁇ GC data processing unit 23 can be realized using software described in Non-Patent Documents 1 and 2.
- the sample introduction unit 11 introduces a sample to be analyzed into a carrier gas sent to the primary column 12 at a substantially constant flow rate in response to an instruction from the analysis control unit 3.
- this sample contains a large number of compounds.
- Various compounds contained in the sample are separated while passing through the primary column 12 that has been temperature-controlled according to a predetermined temperature raising program, and are eluted with a time lag. At this time, not all the compounds are sufficiently separated, and the compounds whose retention times in the primary column 12 are close to each other are eluted (in a mixed state).
- the modulator 13 collects all the compounds eluted from the primary column 12 over a modulation time tm (usually several seconds to several tens of seconds), compresses them in time, and sends them to the secondary column 14 with a very narrow bandwidth. Repeat the operation. Therefore, the compound eluted from the primary column 12 is sent to the secondary column 14 without leakage.

- the designated data is read from the data storage unit 22.
- the modulation time estimation unit 24 creates a one-dimensional chromatogram as shown in FIG. 3A by arranging the read chromatogram data according to the passage of time. Next, the entire curve of the created one-dimensional chromatogram is shifted in the positive direction of the time axis (rightward in FIG. 3) by a predetermined shift time ⁇ (see FIG. 3B), and the shift time ⁇ is gradually increased. While changing (increasing the shift time), the original (that is, not shifted at all) one-dimensional chromatogram and the shifted one-dimensional chromatogram (hereinafter referred to as “time-shifted one-dimensional chromatogram”) Compare
- the gas eluted from the primary column 12 contains the same compound over a plurality of modulation time tm ranges. For this reason, in a one-dimensional chromatogram, a peak derived from a certain compound hardly appears only in one modulation time tm range, and in many cases, the same compound is present in a plurality of continuous modulation time tm ranges. A sharp peak of origin appears.

Therefore, when the shift time ⁇ matches the modulation time tm, the positions of the peaks derived from the same compound in the time shift one-dimensional chromatogram and the original one-dimensional chromatogram (see FIG. 3C). Therefore, the modulation time estimation unit 24 estimates the modulation time tm by obtaining the shift time ⁇ when the peak positions match in this way.
- the regularity of peaks derived from the same compound on the one-dimensional chromatogram can be evaluated by the following method.
- the evaluation function of equation (1) shows a very large value with a peak coincident when the shift time ⁇ is an integral multiple of the modulation time tm.
- the modulation time tm is set within a range of about 1 second to several tens of seconds, so that the evaluation range of the shift time ⁇ is preferably set to 0 second to at least about 20 seconds to about 1 minute.
- the evaluation range of the shift time ⁇ can be narrower than the above range. Note that the integration calculation in equation (1) can be replaced with the sum of sampling intervals.
- the evaluation value F ( ⁇ ) based on the equation (1) is calculated while changing the shift time ⁇ with a predetermined step width over the evaluation range of the shift time ⁇ as described above. Thereby, the relationship between the shift time ⁇ and the evaluation value F (t) is obtained.
- F ( ⁇ ) increases when the shift time ⁇ is 2 times, 3 times,..., The modulation time tm, so in the relationship between the shift time ⁇ and the evaluation value F (t),
- a predetermined number of shift times ⁇ i at which F ( ⁇ ) is maximized are selected in descending order of F ( ⁇ ).
- ⁇ 1 ⁇ 1 ⁇ 0, and if m ⁇ 1 exists in ⁇ 2 to ⁇ n, ⁇ 1 may be set as the modulation time tm. If the peak derived from one compound eluted from the primary column 12 extends over four continuous modulation time tm ranges (generally, the resolution in the primary column 12 is set to this level), m The value may be any integer from 2 to 4.
- ⁇ 2 ⁇ 2 ⁇ 0, and it is determined whether m ⁇ 2 exists in ⁇ 3 to ⁇ n. If m ⁇ 2 exists in ⁇ 3 to ⁇ n, ⁇ 2 is set as the modulation time tm. If m ⁇ 2 does not exist in ⁇ 3 to ⁇ n, m ⁇ i is obtained for a larger ⁇ i and the same process may be repeated.
- the two-dimensional chromatogram creation unit 25 arranges the chromatogram data two-dimensionally in accordance with the obtained modulation time tm, and a two-dimensional chromatogram as shown in FIG. Create As a result, even if the modulation time tm is not given from the outside, that is, operation input by the operation unit 5 or reading of control data from the analysis control unit 3, the modulation time tm automatically estimated. It is possible to create a two-dimensional chromatogram based on the above.
- the method for estimating the modulation time is not limited to the method described above as long as it is a method that can detect the regularity and periodicity of the appearance times of a plurality of peaks that can be assumed to be derived from the same compound on a one-dimensional chromatogram. .
- a general method capable of calculating the correlation coefficient can be used.
