In the figure, 1 is a fermentation tank of a beer factory, and 2 is a fermentation liquid. Reference numeral 3 is an upper valve, and the sample liquid taken in through the upper valve 3 is sent to a sample conditioner 4 to be subjected to depressurization, reduction (heating) temperature, dust removal, flow rate adjustment, and the like. The sample liquid sent from the conditioner 4 is analyzed by the analyzer 5.
The gas contained in the sample is sent to and analyzed.
The used sample solution is returned to the fermentor via the pump 6 and the lower valve 7.

現することにある。In such an apparatus, since the sample liquid is transferred through a valve or a pipe, when the viscosity of the liquid is high, the line is blocked or the sample is depressurized or heated (heated). Therefore, there is a problem that the composition changes, and when a pump is used to return the sample liquid to the fermenter, the cost increases and maintenance work is required. The present invention has been made to solve the above-mentioned problems of the prior art, and is to realize a sampler that does not have a risk of blockage of valves and pipes or composition change and does not need to return a sample solution to a fermenter. .

FIG. 1 is a block diagram showing an embodiment of the present invention. In the figure, 1 is a fermentation tank of a beer factory, and 2 is a fermentation liquid. No. 10 is a member (polymer film) that allows gas or volatile components with a low molecular weight to permeate, but does not allow liquids with a high molecular weight to permeate.
The container 10 contains an inert metal (for example, stainless steel) 11 which is a weight for holding the contact area with the liquid at an arbitrary position. Reference numeral 12 denotes a seal member, and the container 10 has first and second tubes 13 whose outer periphery is sealed by the seal member.
One end of 14 is inserted.

One end of the pressure regulating valve 18 (not shown) cylinder of inert gas serving as a carrier gas (e.g. N 2, H e, A r gas, etc.) are connected. On the other hand, the second tube 14
The other end of is connected to a needle valve 21 that constitutes the flow rate controller 20, and is sent to the analyzer via a flow meter 22. Reference numeral 25 is a pressure gauge for measuring the liquid pressure at a predetermined depth including the pressure inside the fermentor.

るガス量によって決定する。In the above construction, the gas collection container 10 is a cloth-like polymer film, and when it is immersed in the fermentation liquid, the container is submerged in the liquid by the weight 11. However, when the carrier gas is delivered from the other end of the first tube 13 to the container 10, the container becomes stable when it is balanced with the weight 11. The pressure of the carrier gas needs to be sent at a higher pressure than the pressure of the pressure gauge 25, but the position of stabilizing the container is determined by the amount of gas that permeates the GORE-TEX.

ルの廃棄処理も容易である。As described above in detail with reference to the embodiments, according to the present invention, since a sample is taken in the process (in-line), a conventional sample conditioner is not required. Therefore, the cost is low and maintenance is reduced. Also, heavy components / tar / dust (particles)
It can also be applied to process liquids such as. Further, since the volume of the gas collection container can be reduced as necessary, it is also possible to make the actual amount of sample collected from the process small. Therefore, even in a small-scale (small-volume) process, disturbance due to sample withdrawal is less likely to occur, and the sample withdrawn can be easily discarded.
