TPS-MFGDP-MS
The conditions of mass spectrometer were optimized as follows: capillary voltage, 18 V; capillary temperature, 320 ℃; tube lens, 20 V. All spectra were collected under automatic gain mode where per spectrum was set 3 microscans at 100 ms maximum ion injection time. The flow of He through the channel was controlled by a mass flow controller (D08-1F3L, Sevenstar, Beijing, China) at a rate of 1 mL min ?1.
