GTI Glass Twin Impinger

It operates at a specific flow rate (usually 60 L/min) and uses a two-chamber system to separate particles based on their size.

The Glass Twin Impinger (GTI) is the Inpharmatec laboratory device used in the testing of inhalation products, particularly for determining the aerodynamic particle size distribution of aerosols emitted from inhalers. It operates at a specific flow rate (usually 60 L/min) and uses a two-chamber system to separate particles based on their size.

How it Works:

Flow Rate and Cut-off Diameter: The GTI Glass Twin Impinger functions at a flow rate of 60 L/min. It has a cut-off diameter of 6.4 μm, which means it separates particles larger and smaller than this size.
Upper and Lower Impingement Chambers: When the aerosol is introduced into the device, particles larger than 6.4 μm are collected in the upper impingement chamber. Particles smaller than 6.4 μm pass through to the lower impingement chamber.
Purpose: This separation allows researchers to quantify the respirable (small enough to reach the lungs) and non-respirable (too large to reach the lungs) fractions. This information is crucial for evaluating the efficiency and effectiveness of inhalation therapies, ensuring that the medication is delivered properly to the target site within the respiratory system.

Components:

The Glass Twin Impinger (GTI) consists of six primary components:

Base: Provides stability and support for the entire instrument during operation.

Jet Assembly: Directs the aerosol into the device.

Throat: Connects the jet assembly to the rest of the apparatus, guiding the aerosol flow.

Neck: Joins the throat to the impingement chambers.

Upper Impingement Chamber: Collects larger particles (those greater than 6.4 μm).

Lower Impingement Chamber: Collects smaller particles (those less than 6.4 μm).

Together, these components ensure the accurate separation and collection of particles based on size, allowing for precise measurement and analysis of aerosol characteristics in inhalation product testing.
