| titleOfInvention | Sample introduction interface device for ionization source, mass spectrometry and liquid phase gas chromatograph-mass spectrometer |
| abstract | The invention provides a sample introduction interface device for an ionization source, a mass spectrometry and a liquid phase gas chromatograph-mass spectrometer. The sample introduction interface device for the ionization source includes a liquid phase capillary, a gas-liquid spraying pipe, a sheath gas pipeline, a sheath liquid pipeline and a heating component; the liquid phase capillary is provided with a liquid phase inlet; the gas-liquid spraying pipe can convert a liquid sample at the liquid phase outlet of the liquid phase capillary into mist spray and transmit the mist spray to an ionization zone between the outlet of an ion source and the ion sampling opening of the mass spectrometry; the gas-liquid spraying pipe sleeves the liquid phase capillary, so that the gas-liquid spraying pipe and the liquid phase capillary can form a gas-liquid channel; the gas-liquid spraying pipe is provided with a sheath gas inlet and a sheath liquid inlet; the sheath gas pipeline is used for transmitting sheath gas of preset pressure into the gas-liquid channel; the sheath gas pipeline is communicated with the sheath gas inlet; the sheath liquid pipeline is used for transmitting sheath liquid into the gas-liquid channel and is communicated with the sheath liquid inlet; and the heating component is used for heating the mist spray sprayed from the spraying opening of the gas-liquid spraying pipe and is located at one side of the spraying opening of the gas-liquid spraying pipe, wherein the one side of the spraying opening of the gas-liquid spraying pipe is adjacent to the ionization zone. With the sample introduction interface device for the ionization source, the mass spectrometry and the liquid phase gas chromatograph-mass spectrometer of the invention adopted, the influence of inorganic salt and weak-polar organic solvent on the ionization of the mass spectrometer can be decreased, and the application range of the liquid chromatographic-mass spectrometric method can be expanded. |
