The light weight of these products reduces user s shipping costs and conserves energy in transportation. These products are reusable, a key property from economic, ecological, and energy conservation standpoints. Most products are available in bulk densities of 4.0 to 4.8 kg/m (0.25 to 0.30 lb/fT). Average price is about 1.50 per pound from the manufacturer. 

Part (d) of Figure 2.85 illustrates a limit control configuration where the analyzer controller is overruled by temperature when it reaches its high limit. The reason for this limit is energy conservation, because no additional stripping of the light component can be accomplished, once... 

Equation (2.12) also defines the resonance (energy conservation) condition A material energy state Em) only absorbs or emits light, at infinite time, for which co = com or a) = —o) ,. Equation (2.11) suggests that it takes an infinite time to establish this resonance condition. However, in the case of pulsed light, no transitions can take place after the pulse is over, no matter how short. Hence the resonance condition must actually be established in the finite time by which the pulse is over. These issues, as well as others related to dynamics during a pulse, are discussed in the next section.
