INTERFACE OF GAS CHROMATOGRAPH AND MASS-SPECTROMETRIC DETECTOR

摘要

FIELD: measurement equipment.SUBSTANCE: device comprises a tight tube-container 3 for a gas chromatographic capillary column 5, heated with the help of a thermostat 4 and connected to a source of ions 8. With the help of a tee 9 a pipeline 10 is connected to a tube-container 3 for transportation of calibration gas and reagent gas from a calibration module 11 and chemical ionisation via a tube-container 3 into a source of ions 8.EFFECT: possibility to deliver without losses a tested sample from a gas chromatographic capillary column directly into a source of ions, calibration gas and reagent gas from a calibration module and chemical ionisation at structural simplicity and reliability of a source of ions and mass spectrometer as a whole.1 dwg
