3 Terms and Definitions

The following terms and definitions apply to this document. 3.1 Helium ionization detector heliumionizationdector The use of β particles, or photons and other high-voltage discharge energy to the helium atom transitions from the ground state to the excited state, the various levels of the excited state of helium and other grains Sub helium transfer energy to other atoms and molecules and the ionized small devices. Within the device, as long as meet or exceed neon Ionization potential energy, which may be ionized neon. The detector is a high sensitivity, general-purpose gas chromatography detector. 3.2 Radioactive helium ionization heliumionizationwithradioactivesource Helium carrier gas by β particle bombardment gain energy to produce higher-energy excited state. When the sample enters the excited states of helium and its He particles transfer energy to the test component and ionizing atoms or molecules. 3.3 Discharge helium ionization heliumionizationwithdischarge Helium carrier gas under the action of high voltage power supply for generating the stable discharge current. When the sample enters, helium and other particles in the excited state energy Transferred to the test component and ionizing atoms or molecules. It usually includes HVDC helium helium discharge and pulse discharge types. 3.4 Helium photoionization heliumionizationwithphotoion Helium carrier gas by high-energy, high intensity photon flow effects within the detector light emitted to gain energy to an excited state. When the sample enters After the excited states of helium and photons transfer energy to the atoms or molecules and ionize the measured component.

4 Method summary

Using helium ionization detector is equipped with a gas chromatograph, high purity helium purified gas as a carrier gas through a variety of sample processing flow chromatography After using gas chromatography of the quantitative analysis of analytes. ......
