Gas Chromatography System And Method For Analyzing Sample Using Thereof}

The present invention is a gas chromatography system and a method of analyzing a target sample using the same. More specifically, the present invention includes a waste sample collection unit that collects the target sample that has passed through the pre-concentrator, so that the liquid sample flows into the pump when sampling the liquid sample. This relates to a gas chromatography system that prevents and automatically performs continuous operations from sampling to analysis in a single batch, and a method of analyzing target samples using the same.

A gas chromatography system is a type of component analysis equipment that analyzes the components and concentrations of each substance that makes up a gas sample or liquid sample. The gas chromatography system can basically be operated by a pump. When the pump operates at the end of the system, gas or liquid samples are injected, and sampling (concentration, desorption, separation, etc.) and analysis are performed.

Prior documents 1 to 5 disclose gas chromatography systems. When sampling and analyzing gas samples with such a gas chromatography system, no particular problems arise, but when sampling or analyzing liquid samples, there is a problem that the liquid sample may flow into the pump, resulting in pump failure. there is. Conventionally, in order to prevent this phenomenon, the operator first arranges each component of the gas chromatography system for sampling the liquid sample, then samples the liquid sample, and then rearranges each component of the gas chromatography system for analysis to sample the liquid sample. The analysis is performed using a manual method. In addition, while the gas chromatography system developed for liquid sample analysis is optimized for liquid sample analysis, it is not suitable for analyzing gas samples, so it is necessary to rearrange each component of the gas chromatography system for this purpose.

Meanwhile, the applications for gas chromatography systems are gradually expanding. Recently, it has also been used to monitor substances generated during the semiconductor manufacturing process, as shown in Patent Documents 6 and 7. However, during the semiconductor manufacturing process, not only gas but also liquid is generated, so a gas chromatography system is needed to analyze both gas and liquid samples. However, as mentioned above, the conventional gas chromatography system uses a manual method to analyze both. This can lead to longer analysis times, which can ultimately result in consumers having to pay expensive product prices.

In other words, there is an urgent need to develop technology for a gas chromatography system that can carry out sampling and analysis of gas and liquid samples using an automated method rather than a manual method and can prevent pump failure due to the inflow of liquid samples.

The gas chromatography system (1) is a component analysis equipment operated by a pump, and analyzes the components and concentrations of each substance constituting a gas sample or liquid sample.

However, in the conventional gas chromatography system (1), pump failure may occur due to the liquid sample flowing into the pump, so the operator must select the batch type for gas sample, the batch type for liquid sample sampling, and the batch type for liquid sample analysis. There was a problem in that the analysis took a long time because the analysis had to be performed after each component of the system was placed in one of the batch types.

In order to solve this problem, in the present invention, a waste sample collection unit 300 is placed in the gas chromatography system 1.

More specifically, the present invention is a gas chromatography system (1) and a method of analyzing a target sample using the same. The gas chromatography system (1) includes a sample injector (100), a pre-concentrator (200), and a microcolumn. 400, and a detector 500, and may be arranged in an arrangement in which a waste sample collection unit 300 is additionally provided on one end of the pre-concentrator 200. In this arrangement of the present invention, the target sample injected from the sample injector 100 sequentially passes through the pre-treatment concentrator 200 and the waste sample collection unit 300 through a pump connected to one end of the waste sample collection unit 300. It can be discharged to the outside, and when the target sample is a liquid sample, the liquid is accommodated inside the waste sample collection unit 300, while the waste gas formed by evaporation from the liquid sample can be discharged to the outside through a pump. Therefore, the main feature is that even if a liquid sample is sampled, it prevents the liquid from flowing into the pump and allows continuous performance from sampling to analysis even if it is done in a single batch.

That is, the gas chromatography system 1 of the present invention prevents the liquid sample from flowing into the pump by the waste sample collection unit 300, so that the gas chromatography system 1 can be configured in a single batch and automatically This allows continuous performance from sampling to analysis, further reducing analysis time.

Hereinafter, the gas chromatography system 1 according to an embodiment of the present invention and a method of analyzing a target sample using the same will be described in more detail.

Figure 1 schematically shows the overall configuration of a gas chromatography system 1 according to an embodiment of the present invention.

A gas chromatography system 1 according to an embodiment of the present invention includes a sample injector 100 that accommodates a target sample therein; A pre-concentrator 200 that receives the target sample from the sample injector 100, concentrates a portion of the introduced target sample, and desorbs a portion of the concentrated target sample to form a target gas sample; A receiving part 310 having a sealed receiving space therein, an inflow passage 320 through which another part of the target sample that has passed through the pre-concentrator 200 flows into the receiving part 310, and the receiving part.

The sample injector 100 is a configuration that allows an operator to supply a target sample to the gas chromatography system 1, and can accommodate the target sample therein.

The target sample may include one of a gas sample and a liquid sample.

The pre-concentrator 200 is a component that amplifies the concentration of the target sample introduced from the sample injector 100. After concentrating a part of the target sample introduced, a part of the concentrated target sample is desorbed. You can form a target gas sample by doing this.

The pre-concentrator 200 has a porous adsorption material with a plurality of pores disposed therein, so that a portion of the target sample can be adsorbed onto the surface of the adsorption material. It is preferable that the adsorption of the pre-concentrator 200 continues to occur until the introduction of the target sample from the sample injector 100 is stopped.

After the adsorption of the pre-concentrator 200 is completed, heat is applied to the inside of the pre-concentrator 200 by a heating member (not shown), so that a portion of the target sample adsorbed on the adsorption material may be desorbed. The part of the target sample formed by desorption corresponds to the target gas sample. The target gas sample corresponds to a sample that is actually the subject of analysis when the gas chromatography system 1 operates in analysis mode.

Thereafter, the waste sample collection unit 300 transfers another part of the gas sample contained inside the receiving unit 310 by the first pump 710 disposed at the rear end to the first pump through the discharge path 330. It can be discharged to the (710) side.

On the other hand, in one embodiment of the present invention, when the target sample is a liquid sample, the waste sample collection unit 300 passes another part of the liquid sample discharged without being adsorbed while passing through the pre-concentrator 200 into the inlet ( It can be accommodated inside the receiving part 310 through 320). At this time, another part of the liquid sample stored inside the receiving unit 310 may evaporate to form a waste gas, which is disposed at the rear of the waste sample collection unit 300 by the first pump 710. ) can be discharged to the first pump 710 through the discharge passage 330. Even while the waste gas is being discharged, another part of the liquid sample is preferably accommodated inside the receiving part 310 of the waste sample collection part 300.

The desorbed target gas sample may be in the form of one or more analyte substances coated on the surface of the gas particles, and is preferably accommodated inside the pre-concentrator 200. However, depending on the internal environment, the desorbed target gas sample may move from the inside of the pre-concentrator 200 to the pipe on the microcolumn 400 side. If the gas chromatography system 1 operates in the analysis mode described later in this state, the analysis results may be affected, making it difficult to secure analysis reliability.

Considering this, in the present invention, when the gas chromatography system 1 operates in the second sampling mode, the target gas sample is desorbed and formed, and the second pump 720 is operated by the control unit 900. was operated to allow gas having positive pressure to pass through the detector 500 and be introduced into the microcolumn 400 through the third flow path. At this time, it is preferable that the gas having the positive pressure is not introduced into the pre-concentrator 200, but it may be introduced into the pre-concentrator 200.

Figure 7 schematically shows a state in which another part of the target sample flows into the waste sample collection unit 300 when it is a liquid sample according to an embodiment of the present invention.

As described above, the waste sample collection unit 300 includes an accommodating part 310 having a sealed accommodating space therein; an inflow passage 320 through which another part of the target sample that has passed the pre-concentrator 200 flows into the receiving portion 310; and a discharge path 330 through which waste gas formed by evaporating another part of the target sample in the receiving space of the receiving part 310 is discharged from the receiving part 310.

At this time, the other part of the target sample corresponds to the target sample discharged from the pre-treatment concentrator without being adsorbed to the adsorption material disposed inside the pre-treatment concentrator, as described above.

The inflow passage 320 is a configuration corresponding to one end of the second passage, and the sample injector 100, the first valve 610, the pre-treatment concentrator 200, and the second valve 620 are connected through the second passage. Another part of the target sample that has passed may be introduced into the internal receiving space of the receiving part 310. As shown in FIG. 7, when another part of the target sample is a liquid sample, the inflow passage 320 serves as a passage through which the liquid flows, and the liquid sample passing through the inflow passage 320 is received. It may be in the internal accommodation space of unit 310. At this time, a portion of the liquid sample may evaporate in the internal receiving space of the receiving portion 310 to form waste gas (not shown).

The discharge passage 330 is configured to correspond to one end of the first passage, and can discharge the waste gas (not shown) to the first pump 710 through the first passage. As shown in FIG. 7, when the target sample is a liquid sample, the discharge passage 330 serves as a passage through which waste gas (not shown) formed by evaporation from the liquid phase is discharged, and the discharge passage 330 The waste gas (not shown) may move toward the first pump 710 and be discharged to the outside.

In addition, the receiving part 310 has an upper stopper 311 disposed on the upper side as shown in FIG. 7, and the internal receiving space can be sealed by the upper stopper 311.

At this time, it is preferable that the space between the receiving portion 310 and the upper stopper 311 and between the through hole and the inflow path 320 and the discharge path 330 are sealed.

That is, with this structure, the waste sample collection unit 300 collects the liquid sample inside in a liquid state when another part of the target sample is a liquid sample, while the waste gas formed by evaporation from the liquid sample ( (not shown) can prevent the liquid sample from flowing directly into the first pump 710 by discharging it.

It is discharged without being concentrated. In this case, if the target sample is a liquid sample, a failure of the first pump 710 may occur during discharge from the pre-concentrator 200 to the first pump 710. For this reason, the conventional gas chromatography system 1 is operated in a way that the operator arranges the components in a batch form for liquid sample sampling, samples them, and then rearranges them in a batch form for liquid sample analysis for analysis.

The gas chromatography system 1 of the present invention is provided with a waste sample collection unit 300 having the structure described above, so that when the target sample is a liquid sample, another part of the target sample is transferred to the pre-concentrator 200. Even if it is discharged from the waste sample, it does not flow into the first pump 710 but can be accommodated in the receiving part 310 of the waste sample collection part 300, and another part of the target sample evaporates inside the receiving part 310. Only the waste gas formed can be discharged to the first pump 710, so sampling and analysis can be performed even in a single batch.

In other words, the present invention prevents the liquid sample from flowing into the pump by the waste sample collection unit 300, so that the gas chromatography system 1 can be formed in a single batch form and automatically performs continuous operation from sampling to analysis. This can have the effect of further reducing the analysis time.

On the other hand, although not shown in FIG. 7, when part of the target sample is a gas sample, the waste sample collection unit 300 temporarily collects the gas sample into the internal receiving space of the receiving unit 310 through the inflow passage 320. After that, it can be discharged to the first pump 710 through the discharge passage 330. That is, the waste sample collection unit 300 may correspond to an open pipe when part of the target sample is a gas sample.
