For example, if you started analyzing continuous samples at 2:30 pm on August 1, 2006, a folder will be created as “2006-08-01__14_30_SAM”, and the analysis data type of the stored continuous samples is measured in Excel file. -Month-Day Hour: Minutes: Seconds and above, including hardness and direction of travel (360 °), peak area, calculated concentration (pptv) and flow rate at the time of measurement (Water Flow, ml / min) .

As described above, the present invention having the configuration as described above enables location tracking according to the real-time analysis concentration through a GPS (Global Postioning System) module that can obtain location information on a gas chromatograph. The measured data is calibrated with standard gas to display the calibration concentration data and position information, and the integrated data can be displayed with the difference in the upper and the longitude coordinates. It consists of a one-time measurement mode using a syringe (Syringe), and a calibration mode for measuring standard gas, so that each mode can be automatically analyzed, so that the handling is easy and the execution is easy.

In the above description of the preferred embodiments of the present invention by way of example, the scope of the present invention is not limited only to these specific embodiments and those skilled in the art are appropriate within the scope described in the claims of the present invention. It will be possible to change.
