Abstract
An in-situ particle monitor in an exhaust controls a particle sampler so that when a predetermined particle threshold is detected, the particle sampler is caused to gather samples from the exhaust in real-time. Electrical control signals are monitored to correlate variations in the signals with particle excursions for both analysis and sample collection triggering.
