| description abstract | The design of an improved sampler for the automatic collection of air samples during atmospheric halogenated tracer experiments is described. In this approach, each sample is collected in a small volume (20 to 150 ml) syringe using a rack and pinion drive powered by a precision stepper motor. The sampling rate is controlled via a quartz crystal oscillator and clock to yield averaging periods from 2 to 120 minutes per syringe, and as many as twelve syringe samples can be collected sequentially. Start-up of the sampler is pre-selected using a digital clock and calendar. The sampler is battery-powered, portable and designed for rugged field use. Sample return rates as high as 97% have been achieved in a number of large tracer field programs. Typical results from several of these investigations are also presented. | |
