Tenders are invited for Amc for triton plus thermal ionization mass spectrometer si.no.
Further, some attempts have been made to estimate in-cylinder air-to-fuel ratio from the current signal [20], since the thermal ionization peak amplitude shows a non-linear correlation with this parameter.
As a result, the diffusion and heat convection in the pressure range of 2-3 bar decrease, and the thermal ionization brought by the electron avalanche plays an important role.
Calcote and King considered only positive ions formed by thermal ionization in their equilibrium calculations.
This implies the existence of stronger thermal ionization and phonon-assisted nonradiative decay at the deep-trapped DA state with the relatively stronger Coulomb interaction [24].

The slope of the initial part of the plot characterizes the activation energy value [DELTA]E for thermal ionization of the trap, and the value 1n ([I.sub.tn]/[I.sub.0])--the probability of the tunnelling process from the excited state of the centre.
The CC's findings specify that the acquisition of GV Instruments would significantly affect the markets for gas IRMS and thermal ionization mass spectrometry (TIMS) instruments.
They analyzed lead concentrations using high-resolution inductively coupled plasma mass spectrometry to make preliminary isotopic measurements, followed by thermal ionization mass spectrometry measurements.
The use of this method is likely to become more widespread as a result of the development of the Negative Thermal Ionization Mass Spectrometry developed in the 1990s.
