Figure 7. Reproduction of lap-top computer display of temperature vs. time 

 during sampling with SIS . Note hysteresis in manifold temperature 

 profile (short dashes) relative to that for the temperature sensor in the 

 nozzle (solid line) . The temperature range displayed is easily 

 selectable during sampling. Digital information is also displayed in 

 real time (not shown) .
