| Zusammenfassung: | The utility model relates to a capillary shunting device, in particular to a capillary shunting head of a gas chromatograph. The capillary shunting head comprises a gas inlet tube, a gas outlet tube and an injection port channel, wherein both the gas inlet tube and the gas outlet tube are in a hollow cylinder shape, the injection port channel is in a cylindrical channel shape, and both the gas inlet tube and the gas outlet tube are communicated and connected with the injection port channel. Most of samples and impurities can be directly discharged from the shunting head through the gas outlet tube when the injection port channel injects the samples, and the diaphragm cleaning capacity of the shunting head is improved, so that the capillary shunting head has the advantage that the cleaning capacity is improved. |
