The experimental resin cements were prepared in two pastes in order to avoid chemically initiated polymerization and preionization
of acidic monomers.

and high gas pressure using laser output power measurement", J.
Following the preionization
resolution in the first dimension, the second-dimensional IM-MS employed a hybrid electrospray quadrupole ion mobility time-of-flight mass spectrometer and added an extra postionization separation for between-class OH-PBDE congeners on account of their relative mobility disparity during a very short period of 8.8 ms.
An electron cyclotron resonance heating (ECRH) system with eight gyrotrons has been operated for preionization
and plasma heating.
The increasingly popular technique of mass spectrometry is described, along with 5 types of preionization
; ESI (electrospray ionization) and MALDI (matrix-assisted laser desorption/ionization) are widely used, with TOF (time-of-flight) detection, and precision is attained to 6 figures.
