Argon parameters

To test the minimisation In the predominantly Ionic case, we used the argon parameters for the Lennard-Jones potentials In KCl. Convergence constants = 0.15 A", = rep 0-20 A and summation limit = 8 A were used. In the minimum, a = 6.052 Coul...

An important parameter when considering GC resolution of the sample components is the carrier gas linear velocity (flow rate, F), which can be determined by injecting 5-50 /A of argon or butane and measuring the time from injection to detection by the mass spectrometer. An optimum linear velocity using helium as a carrier gas is approximately 30 cm/sec and... 

At higher pressure (i.e., atmospheric), the reactant gas must be diluted with an non-reactive gas, such as hydrogen or argon, to prevent vapor-phase precipitation, while generally no dilution is necessary at low pressure. However, atmospheric-pressure reactors are usually simpler and cheaper, and, with proper control of the deposition parameters, satisfactory deposits may be obtained.
