[0031] Working principle: The utility model provides an automatic hydrogen sulfide determination device. Before using the automatic hydrogen sulfide determination device, the communication public port 12 on the host body 15 needs to be connected to the PC to synchronize data, and the type and specification of the hydrogen sulfide detection tube in the installation device 21 are configured on the host body 15. At the same time, a plurality of hydrogen sulfide detection tubes are placed in the installation slot 19 of the installation device 21 in sequence. Before the test starts, the detection bag containing the sample to be tested (hereinafter referred to as the detection bag) is placed in front of the external camera 3 for scanning to obtain the barcode information on the detection bag, so as to select the sampling port of the sample to be tested, confirm the selected injection port 1, and then the driving motor on the host body 15 will move the installation device 21 along the channel 11 toward the inner detection chamber, so that the hydrogen sulfide detection tube placed in the installation device 21 passes through the cutting device 5 to cut off the two ends of the hydrogen sulfide detection tube, and then the fastening tube 27 on the fastening device 4 moves downward under the action of the driving member, and the fastening tube 27 passes through the feed through hole 17 and is downwardly sleeved on the upper and lower ends of the hydrogen sulfide detection tube to fix the hydrogen sulfide detection tube.

The hose of the bag to be detected is connected to the sample inlet 1 on the main body 15. After the inside of the sample inlet 1 is connected to the end of the three-way valve 22 on the quantitative tube, the three-way valve 22 on the quantitative tube will be opened, and the substance in the bag to be detected will squeeze the tube body 23. At this time, the tube body 23 will flow along with the bag to be detected. The three-way valve 22 will expand due to the entry of the sample inside, and then the one-way valve 24 at the other end will be closed. Due to the continuous input of gas, the tube body 23 is squeezed by the host body 15, allowing the gas to be tested to flow through the hydrogen sulfide detection tube through the sampling tube 25 on the fastening device 4. At this time, the hydrogen sulfide detection tube will change color, and the internal camera 6 inside the detection room will collect image information of the hydrogen sulfide detection tube, thereby analyzing the hydrogen sulfide content of the sample and transmitting the data to the LIMS system through the communication public port 12 of the host body 15.
