The method of generating this device is to load a sample on the cartridge and spray it all. Exams are also realized even in small samples with less generated loss.
This is an inhalation experimental device optimized for the high -distributed processing method (TAQUANN method) developed by the National Institute of Hygiene.
The injection cartridge shown in the figure on the right allows animals to inhale in the ideal distributed state.

What is the Taquann method?
This is a method that allows you to obtain highly distributed dried samples with a technology inspired by the "critical point drying" used to create a sample of a scanning electron microscope. The sample is suspended in the Tert-butyl (T-BU), the aggregate is filtered, the liquid is coagulated with liquid nitrogen, and the T-BU is sublimated to remove the T-BU in the vacuum. This method is suitable for nanomaterials that are difficult to dispers.
