โœฆ Synopsis

In order to investigate atomization phenomena in premixed flames at low pressure 1, a nebulizer of the total-consumption type had to be built into the low pressure set-up. It is very difficult to run reproducible flame experiments at low pressure with waste liquids accumulating in the vacuum chamber. Therefore a special pneumatic sprayer was developed giving a very high efficiency ( > 9 8 % ) at low pressures. Fortunately this sprayer turned out to have excellent performances, not only at the low pressures for which it was developed (20-100 torr), but also at atmospheric pressure.

This paper reports on the construction of this nebulizer and presents some data on its performance in a normal set-up for atomic absorption measurements at atmospheric pressure. The efficiency of the burner is compared with data from the literature and atomic absorption sensitivities are reported for a few metals.
