This system automatically prepares samples for analysis from the emitted dose from an inhaler. A burst from the Metered Dose Inhaler is sprayed into the Collection Chamber of this machine. The machine then adds a programmed volume of Internal Standard, and washes the spray from the inhaler with a specified solvent, mixes it, and collects it in duplicate in an HPLC vial, which is stored in a thermoelectrically cooled Sample Storage Rack.
Single dose sample prep every 10-14 minutes
Undetectable level of carry-overs
Sample injector counter
Stores samples directly in HPLC vials
To minimize solvent evaporation, HPLC vials stored in cooled sample rack
This System is controlled using an embedded control system running Win CE.
The System has a closed loop control to maintain vacuum induced flow.
