|
1.EI ion source
|
double filament, with 10-300eV ionization energy and 150 ºC-350 ºC of heating temperature. |
|
2.Sample injection interface
|
Non-cold point heat tracing technology is adopted for the MS/MS interface, and the interface temperature is 50-400 ºC, so as to ensure the efficient transmission of GC-MS/MS samples. |
|
3.Ion optical system
|
|
| 90° deflection is adopted to effectively filter the unionized neutral particles, so as to reduce the background noise and avoid the pollution to the detector. | |
| No redundant transmission pole is set in the ion transmission system, and the ions can directly enter Quadrupole to avoid ion loss during transmission. | |
|
