Sympatec Spray Sizing Adapter: SPRAYER, for MDIs, DPIs and pump sprays

High resolution spray analysis with SPRAYER comprising bench, operational panel,
trajectory actuator (with software control of stroke, velocity and acceleration definition), extraction unit and cover.

Technical specifications and dimensions.

The SPRAYER is a versatile adapter of pump sprays or propellant gas sprays to the HELOS sensor for the measurement of particle and droplet size distributions.

As the results are usually depending on a variety of parameters, e.g. the force or the time behaviour driving the spraying process, the distance to the measuring volume, the orientation of the spraying direction with respect to the direction of the gravity of earth, etc., the spraying process has to be performed under controlled conditions:

The actuating piston can be controlled by software in terms of acceleration, velocity, stroke length by the electronic trajectory actuator. Alternatively the electronic force actuator can be used, if the piston has to be driven at a constant, definable force. The complete actuation process is controlled and monitored by software for subsequent evaluation.
The distance of spray outlet to the measuring volume can be varied under software control.
The direction of the spray can be varied by using ROTOR/M as an option.

The SPRAYER can be easily adapted to the different styles of the spray bottles. The direction of the piston is adjustable.

The measurement can be performed by the WINDOX software in three different modes:

Integration over the complete spraying process
Separation of the results in three phase: Start, middle, end, as requested by the FDA.
Time resolved measurements with definable resolution up to 2000 particles size distributions per second.

The SPRAYER can be applied to all members of the HELOS family. For the operation an extraction unit is required for sample collection and the generation of a laminar air flow in the measuring zone of the HELOS.

For inhalers or nebulizers please refer to INHALER.

Options

The SPRAYER is available in two versions: With Trajectory Actuator or with Force Actuator. The SPRAYER can be extended by the complementary actuator, as an option.
