ABSTRACT:
A dual power-supply system is used to produce a sharp rise-time characteristic and a high steady-state temperature in a platinum ribbon pyrolysis probe. First, a small "boost" power supply generates a very short, high power pulse that is applied to the probe. Then, at its peak, the first power supply is effectively disabled and a second power supply is brought into play to maintain the power (and the temperature) in the probe at a high steady-state value approximating the peak value of the boost pulse.
