Surface acoustic wave (SAW) piezoelectric sensors typically used by researchers in analytical applications are based on SAW delay lines. We report here the development of a 200 MHz SAW instrument based on a SAW resonator instead of a conventional del

Sulphur dioxide emission rates were measured at Mount Etna, Italy during July 1987 while the volcano was undergoing relatively ‘quiet’ activity. The SO2 flux averaged 930 ± 587 (1σ) Mg/d, excluding 19 July when the flux was 3200 ± 1730 (1σ) M

The development of a particulate mass-sensing instrument based on a quartz-crystal microbalance and enhanced with the new surface acoustic-wave (SAW) technology is reported. Mass sensitivity comparisons of a 158-MHz SAW piezoelectric microbalance and

Very small carbonaceous particles, thought to be meteoritic, have been found in small quantities in the lower stratosphere during aircraft sampling flights. The sampling was accomplished using a quartz crystal microbalance (QCM) cascade impactor oper

Durante el periodo comprendido desde abril hasta diciembre de 1982 se hicieron mediciones y muestreos in situ de la nube de la erupción de El Chichón, a 18 - 21 km de altitud, para examinar las características físicas y químicas de las partícul

A simple technique for the recovery of oil from the water surface is by the use of rotating disks which are preferentially wet by the oil which is then collected from the disks with wipers. The principal also is utilized with rotating devices. The po

Cascade impactors can collect particles from gases for SEM/EDX analyses. However, additional work is required to verify system design and interface requirements between impactor and gas source. This paper describes an experiment using a 4-stage casca
