    Abstract: A compact apparatus for atomisation of fluid samples comprises a sonotrode (11), placed so that an ultrasonic wave emitted by the sonotrode is directed through a channel (25) in a separate channel device (21) and reflected by from the interface (26) in a high-low impedance transition zone (Tz), so that a standing wave is formed within the channel.

    Abstract: A digital processor of a nebulizer controller controls and monitors drive current (I) applied to an aperture plate. The drive current is detected as a series of discrete values at each of multiple measuring points, each having a particular drive frequency The processor in real time calculates a slope or rate of change of drive current with frequency and additionally determines a minimum value for drive current leading up to the peak value. The processor uses both the value of the minimum drive current during the scan and also the maximum slope value to achieve reliable prediction of end of dose, when the aperture plate becomes dry.

    Abstract: Various arrangements for determining an atomization element of a nebulizer is dry are presented. The vibratable element of the nebulizer may be energized with an electrical signal that sweeps from a first frequency to a second frequency. While energizing the vibratable element of the nebulizer with the electrical signal that sweeps from the first frequency to the second frequency, a sequence of impedance values of the vibratable element of the nebulizer may be measured. The sequence of impedance values of the vibratable element of the nebulizer may be analyzed to determine if the atomization element of the nebulizer is wet or dry.
