... A property is a macroscopic characteristic of a system such as pressure, temperature, volume, and mass. At a given state each property has a definite value independent of how the system arrived at that state. The properties of air in state 1 shown in Figure 1.1 are: pressure at 1 atm, temperature at ...

Determination of the Vapor Pressure of Triacetone Triperoxide (TATP)
... Typical calibration curves (peak area versus µg TATP or TNT) are given in Figure 2 for TATP and Figure 3 for TNT. Linearity, as expressed by the square of the correlation coefficient, exceeded 0.99 for all calibration curves. The GC was used to determine the µg of TATP or TNT in fixed volumes (10 µL ...
