The present invention relates to a purifier for purifying the harmful gas and odor contained in the gas discharged from the gas analysis device, such as noxious gas and odor, more specifically, by filtering the harmful gas and odor exhausted after the analysis process is completed Touch screen displays the setting and input of the operating conditions of the system while visually displaying information on the operating status of the system, such as setting the operating conditions and operating conditions of the purifier to be discharged to the atmosphere. The present invention relates to a harmful gas and odor purifying apparatus and a method of operating the gas analyzer having a touch screen, which can be conveniently controlled by using.

Gas component analysis includes a thermal conductivity detector (TCD), gas chromatography (GC), or Orzat (Orsat) analysis. GC is a technique for separating two or more components into a single component. In other words, each component of the material to be separated into two kinds of phases is present in the stationary phase and the mobile phase. Separation will be made.

This is a method that separates gas with simple molecular structure and analyzes it in order of passing through gas through column filled with filling, and monitors and detects pesticides or organic compounds remaining in water soil.

GC to which the present invention is applied is a method for identifying and quantifying organic compounds according to gas chromatograph. Among the organophosphorus compounds, ipiene, parathion, methyldimethone, diazinone, pentoate, etc. By checking each component of the and measuring the height or area of the peak is to quantify the organophosphorus.

Typical configurations of such GCs include high pressure cylinders of carrier gas with pressure regulators and flow meters; Sample injector; column; A detector for detecting components separated through the column; An electrometer and a recorder for converting and recording the signal detected by the detector; And a constant temperature device capable of adjusting the temperature of each part of the sample injector, column and detector.

The recorder is a strip chart type automatic balance recorder having a span voltage of 1 (mV), a fan response time of less than 2 seconds, and a recording paper moving speed of 10 mm / min.

The conventional GC is connected to a recorder without a means for storing the measurement data therein, and can output only the measurement data after gas measurement, and requires an operator to record and manage the measurement data.

In addition, a vent hole through which the gas used for measurement is discharged is formed in the casing of the GC main body, and the gas used for the measurement is released into the atmosphere through the vent hole. Most of the emitted gas is flammable, toxic, and explosive. Of course, since it may contain components that may be harmful to the human body or cause air pollution, there is a problem that threatens the environmental pollution and the health of the user is required to properly discharge the filtered and purified treatment.
