Detailed Description
Specific examples of the present invention will be described in further detail below. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.
Fig. 1 to 4 are schematic structural diagrams of a sample connection device for a chromatograph according to the present invention. The utility model provides a sample links up device for chromatograph, includes dry connector 10, dry connector 10 one end be equipped with air inlet 11 and be used for with sample bag sealing connection, the dry connector 10 other end be equipped with gas outlet 12 and be used for with chromatograph sealing connection, be equipped with respectively in the dry connector 10 with air inlet 11 with dry tube 13, power 14 and with the treater 15 that the power 14 electricity is connected of gas outlet 12 intercommunication, be equipped with dry granule 131 in the dry tube 13 and be used for responding to dry granule 131 degree of dryness and with treater 15 wireless connection's dry inductor 16, dry tube 13 both ends opening is equipped with respectively and is used for preventing dry granule 131 in the outer net 132 that blocks of dry tube 13, be equipped with on the dry connector 10 lateral wall with treater 15 connect and with the display screen 17 that the power 14 electricity is connected, for displaying the dryness value of the dried particles 131.
When the device is used, one end of a gas outlet 12 of the drying connecting body 10 is firstly in sealing connection with an opening of a chromatograph, and then one end of a gas inlet 11 is in sealing connection with a sampling bag, wherein gas in the sampling bag enters a drying tube 13 in the drying connecting body 10 through the gas inlet 11, the gas reacts with the dry particles 131 to absorb moisture in the gas, the gas is discharged from the gas outlet 12 and enters the chromatograph, and the dried gas enters a 5A molecular sieve chromatographic column of the chromatograph to cause the chromatographic column, so that the analysis result is accurate; and the drying sensor 16 may sense the dryness of the dry particles 131 (for example, after the dry connector 10 is used for a period of time, the drying intensity of the dry particles 131 may decrease), and wirelessly transmit the sensed data to the processor 15, the processor 15 processes the data and transmits the data to the display 17, and the display 17 displays the percentage value of the dryness of the dry particles 131 for the user to view.
The dry connecting body 10 extends from the periphery of the air inlet 11 to form an air inlet pipe 111, and the dry connecting body 10 extends from the periphery of the air outlet 12 to form an air outlet pipe 121. So that the gas in the sampling bag can more easily enter the drying tube 13 of the dry connector 10 from the gas inlet tube 111 and be dried, and the dried gas enters the chromatograph through the gas outlet tube 121 for detection.
