Figure Bl.26.5. Plot of InCP/PQ) versus 1/6 for argon on graphitized carbon black at 77 K (from the argon data in figure B 1,26.4) (Eggers D F Jr, Gregory N W, Halsey G D Jr and Rabinovitch B S 1964 Physical Chemistry (New York Wiley) eh 18).

Using 16.2 A2 as the N2 cross section, calculate Asp for the silica by the BET method. What value of o° is required to give the same BET area for the argon data ... 

Figure 7.1-12. Energy stored in a gas pressurised vessel as function of pressure and the energy equivalent in mass of TNT according to a volume of 1 fit3 and a gas with an adiabatic coefficient c = 1.66 (Argon). Argon data are based on the Redlich-Kwong - Equation of State. These curves should only be used as a guide. Variation of temperature within a vessel must be considered [19],...

Fig. 6.5. Examples of positron lifetime spectra for (a) argon and (b) xenon gases. The argon data are for a density of 6.3 amagat at 297 K. The channel width is 1.92 ns. In (a), (i) shows the raw data, (ii) shows the signal with background removed, (iii) shows the free-positron component and (iv) shows the fitted ortho-positronium component. In (b), the spectrum for xenon is for room temperature and 9.64 amagat and has a channel width of 0.109 ns. The inset shows the fast components as extracted and discussed by Wright et al. (1985).

For the detection, a tandem mass spectrometer Quattro Micro API ESCI (Waters Corp., Milford, MA) with a triple quadrupole was employed. The instrument was operated in electrospray in the positive ionization mode (ESI+) with the following optimized parameters capillary voltage, 0.5 kV source block temperature, 130 °C nebulization and desolvation gas (nitrogen) heated at 400 °C and delivered at 800 L/h, and as cone gas at 50 L/h collision cell pressure, 3 x 1(F6 bar (argon). Data was recorded in the multiple reaction monitoring (MRM) mode by selection of the two most intense precursor-to-product ion transitions for each analyte, except for the ISs, for which only one transition was monitored. The most intense transition for each analyte was used for quantitative purposes. Table 2 shows MRM transitions, cone voltages and collision energies used for the analysis of the antidepressants included in the LC-MS/MS method. 

The greatest problem is that of determining the absolute age of the Pliocene-Pleistocene boundary. The age of the Gilsa palaeomagnetic event is estimated as 1.6-1.8 million years B.P., whereas e.g. K-Argon data from the Perrierian Pliocene-... 

Chen and Kreglewski [11] developed a perturbation equation based on Boublik s [12] hard-convex-body equation as the reference fluid equation. The repulsive pressure is Alder et al. s double-series polynomial with modified coefficients fitted to experimental argon data. The Boublik-Alder-Chen-Kreglewski (BACK) eos is... 

For a substance like argon, with T set at 50° K and E only 3.0 kJ/mol, A7 a l9°K, which is essentially in agreement with the computer simulation results of Clarke. A laboratory glass transition centered at 50°K would have ATpsj2°K. Some of the argon data are reproduced in Fig. 7, which...
